[ { "from": "human", "value": "What are the symptoms of Catecholaminergic polymorphic ventricular tachycardia?" }, { "from": "gpt", "value": "The symptoms typically start with ventricular tachycardia (VT) during physical activity or emotional stress:\nFainting is commonly the first sign of the disease Light-headedness or dizziness Palpitations or unpleasant awareness of the heartbeat\nSometimes the ventricular tachycardia goes away, and symptoms stop. At times, ventricular tachycardia can turn into ventricular fibrillation (VF) in which the ventricles quiver and are unable to pump blood. This sudden loss of heart function leads to sudden cardiac arrest. A person stops breathing and becomes unresponsive. Unfortunately, sudden cardiac arrest is sometimes the first sign of CPVT. Sudden cardiac arrest can lead to sudden cardiac death." } ]

[ { "from": "human", "value": "What causes Catecholaminergic polymorphic ventricular tachycardia?" }, { "from": "gpt", "value": "CPVT is caused by a gene defect (abnormal gene). Genes are part of your DNA, the material passed down from parents to children, which can be passed down through families and inherited in different ways (from either one or both parents). In some cases, CPVT is autosomal dominant which means you need an abnormal gene from only one of your parents to have it. In other cases, CPVT is autosomal recessive which means you need an abnormal gene from both of your parents to get the disease. CPVT can result from mutations in genes such as RYR2 and CASQ2. RYR2 gene mutations cause about half of all cases, while mutations in the CASQ2 gene account for 1 percent to 2 percent of cases. The RYR2 and CASQ2 genes provide instructions for making proteins that help maintain a regular heartbeat. For the heart to beat normally, heart muscle cells called myocytes must tense (contract) and relax in a coordinated way. Both the RYR2 and CASQ2 proteins are involved in handling calcium within myocytes, which is critical for the regular contraction of these cells. Mutations in either the RYR2 and CASQ2 gene disrupt the handling of calcium within myocytes. During exercise or emotional stress, impaired calcium regulation in the heart can lead to ventricular tachycardia in people with CPVT. Stress and exercise can trigger episodes. Certain medicines, such as catecholamines, can also make it worse." } ]

This may cause a severe headache that a patient may describe as \"the worst headache of my life.\" Another phrase used to describe this is a sentinel headache. This means the headache could be a warning sign of a rupture days or weeks after the headache first happens.\nSymptoms may also occur if the aneurysm pushes on nearby structures in the brain or breaks open (ruptures) and causes bleeding into the brain.\nSymptoms depend on the location of the aneurysm, whether it breaks open, and what part of the brain it is pushing on, but may include:\nDouble vision Loss of vision Headaches Eye pain Neck pain Stiff neck\nA sudden, severe headache is one symptom of an aneurysm that has ruptured. Other symptoms of an aneurysm rupture may include:\nConfusion, lethargy, sleepiness, or stupor Eyelid drooping Headaches with nausea or vomiting Muscle weakness or difficulty moving any part of the body Numbness or decreased sensation in any part of the body Seizures Speech impairment Stiff neck (occasionally) Vision changes (double vision, loss of vision)\nNOTE: A ruptured aneurysm is a medical emergency.

An aneurysm may be present from birth (congenital) or it may develop later in life, such as after a blood vessel is injured.\nThere are many different types of aneurysms. A berry aneurysm can vary in size from a few millimeters to over a centimeter. Giant berry aneurysms can reach well over 2 centimeters. These are more common in adults. Multiple berry aneurysms are inherited more often than other types of aneurysms.\nOther types of cerebral aneurysm involve widening of an entire blood vessel, or they may appear as a \"ballooning out\" of part of a blood vessel. Such aneurysms can occur in any blood vessel that supplies the brain. Atherosclerosis, trauma, and infection, which can injure the blood vessel wall, can cause cerebral aneurysms." } ]

Some causes are mildly inconvenient, while other causes are serious, even life-threatening. Any organ or tissue in your chest can be the source of pain, including your heart, lungs, esophagus, muscles, ribs, tendons, or nerves.\nHeart problems that can cause chest pain:\nAngina is a type of heart-related chest pain. This pain occurs because your heart is not getting enough blood and oxygen. The most common symptom is chest pain that occurs behind the breast bone or slightly to the left of it. It may feel like tightness, heavy pressure, squeezing, or crushing pain. The pain may spread to the arm, shoulder, jaw, or back. Heart attack pain can be similar to the pain of unstable angina, but more severe. Aortic dissection causes sudden, severe pain in the chest and upper back. Inflammation or infection in the tissue around the heart (pericarditis) causes pain in the center part of the chest.\nLung problems that can cause chest pain:\nPneumonia, which causes chest pain that usually feels sharp, and often gets worse when you take a deep breath or cough A blood clot in the lung (pulmonary embolism), collapse of a small area of the lung (pneumothorax), or inflammation of the lining around the lung (pleurisy) can cause chest pain that usually feels sharp, and often gets worse when you take a deep breath or cough Asthma, which generally also causes shortness of breath, wheezing, or coughing\nOther causes of chest pain:\nStrain or inflammation of the muscles and tendons between the ribs Inflammation where the ribs join the breast bone or sternum (costochondritis) Shingles (sharp, tingling pain on one side that stretches from the chest to the back) Anxiety and rapid breathing\nChest pain can also be related to the following digestive system problems:\nHeartburn or gastroesophageal reflux (GERD) Stomach ulcer (burning pain occurs if your stomach is empty and feels better when you eat food) Gallbladder (pain often gets worse after a meal, especially a fatty meal)\nIn children, most chest pain is not caused by the heart." } ]

These are called right-sided heart failure or left-sided heart failure. More often, both sides of the heart are involved.\nHeart failure is present when:\nYour heart muscle cannot pump (eject) the blood out of the heart very well. This is called systolic heart failure.\nYour heart muscles are stiff and do not fill up with blood easily. This is called diastolic heart failure.\nBoth of these problems mean the heart is no longer able to pump enough oxygen-rich blood out to the rest of your body, especially when you exercise or are active.\nAs the heart's pumping action is lost, blood may back up in other areas of the body. Fluid builds up in the lungs, liver, gastrointestinal tract, and the arms and legs. This is called congestive heart failure.\nThe most common cause of heart failure is coronary artery disease (CAD), a narrowing of the small blood vessels that supply blood and oxygen to the heart.\nHeart failure can also occur when an infection weakens the heart muscle. This condition is called cardiomyopathy.\nOther heart problems that may cause heart failure are:\nCongenital heart disease Heart attack Heart valve disease Some types of abnormal heart rhythms (arrhythmias)\nOther diseases that can cause or contribute to heart failure:\nEmphysema Overactive thyroid Severe anemia Underactive thyroid" } ]

For example, patients with class IV heart failure have the poorest prognosis, while patients with class I have the best.\nHeart function: The ejection fraction of left ventricle (LVEF) is an important indicator of the prognosis. The more severely damaged your heart muscle is, the worse your ejection fraction and worse prognosis will be, regardless of your symptoms.\nThe causes of heart failure: Heart failure associated with alcohol use or pregnancy may spontaneously recover itself over time. Heart failure can be caused by treatable conditions such as hyperthyroidism or hypothyroidism, anemia, or vitamin deficiency. The prognosis of these conditions are generally excellent. Heart failure as a result of a valve condition may also be reversible if the valve problem is recognized early and fixed before permanent damage happens. People with heart failure caused by severe hypertension may see considerable improvement of their symptoms when they control their hypertension. But the majority of patients have heart failure as a result of coronary artery disease (CAD) have a worse prognosis and a higher death rate than people who have heart failure that is not a result of CAD.\nHow long you've had heart failure: There is no specific length of time after which your heart function is unlikely to improve. General speaking, the longer you have had heart failure, the poorer prognosis may be even with appropriate treatment.\nCompensatory factors: \"compensatory factors\" are various adjustments to correct the effects of heart failure on other organs. When heart failure occurs, various hormone levels including renin, aldosterone, norepinephrine, atrial natriuretic peptide, and prostaglandin, may increase. Increases in these hormonal factors and other compensatory factors often make heart failure worse over time." } ]

[ { "from": "human", "value": "What to expect during coronary artery bypass grafting?" }, { "from": "gpt", "value": "Coronary artery bypass grafting (CABG) requires a team of experts. A cardiothoracic surgeon does the surgery with support from an anesthesiologist, perfusionist (heart-lung bypass machine specialist), other surgeons, and nurses. There are several types of CABG. They range from traditional surgery in which the chest is opened to reach the heart, to nontraditional surgery in which small incisions (cuts) are made to bypass the blocked or narrowed artery.\nThis type of surgery usually lasts 3 to 5 hours, depending on the number of arteries being bypassed. Numerous steps take place during traditional CABG. You'll be under general anesthesia for the surgery. The term \"anesthesia\" refers to a loss of feeling and awareness. General anesthesia temporarily puts you to sleep. During the surgery, the anesthesiologist checks your heartbeat, blood pressure, oxygen levels, and breathing. A breathing tube is placed in your lungs through your throat. The tube is connected to a ventilator (a machine that helps you breathe). An incision is made down the center of your chest. The chest bone is then cut and your ribcage is opened so that the surgeon can get to your heart. Medicines are used to stop your heart, which allows the surgeon to operate on it while it's not beating. You're also given medicines to protect your heart function during the time that it's not beating. A heart-lung bypass machine keeps oxygen-rich blood moving throughout your body during the surgery. An artery or vein is taken from your body—for example, from your chest or leg—and prepared to be used as a graft for the bypass. In surgery with several bypasses, both artery and vein grafts are commonly used.\nArtery grafts. These grafts are much less likely than vein grafts to become blocked over time. The left internal mammary artery most often is used for an artery graft. It's located inside the chest, close to the heart. Arteries from the arm or other places in the body are sometimes used as well.\nVein grafts. Although veins are commonly used as grafts, they're more likely than artery grafts to develop plaque and become blocked over time. The saphenous vein—a long vein running along the inner side of the leg—is typically used.\nAfter the grafting is done, blood flow to your heart is restored. Usually, the heart starts beating again on its own. In some cases, mild electric shocks are used to restart the heart. You're then disconnected from the heart-lung bypass machine. Tubes are inserted into your chest to drain fluid. The surgeon uses wires to close your chest bone (much like how a broken bone is repaired). The wires stay in your body permanently. After your chest bone heals, it will be as strong as it was before the surgery. Stitches or staples are used to close the skin incision. The breathing tube is removed when you're able to breathe without it.\nNontraditional CABG includes off-pump CABG and minimally invasive CABG.\nOff-pump coronary artery bypass grafting: This type of surgery can be used to bypass any of the coronary (heart) arteries. Off-pump CABG also is called beating heart bypass grafting because the heart isn't stopped and a heart-lung bypass machine isn't used. Instead, the part of the heart where grafting is being done is steadied with a mechanical device.\nMinimally invasive direct coronary artery bypass grafting: There are several types of minimally invasive direct coronary artery bypass (MIDCAB) grafting. These types of surgery differ from traditional bypass surgery. They only require small incisions rather than opening the chest bone to get to the heart. These procedures sometimes use a heart-lung bypass machine.\nThis procedure is done through small incisions (ports) made in your chest. Artery or vein grafts are used. A heart-lung bypass machine is used during this procedure.\nThis type of procedure allows for even smaller, keyhole-sized incisions. A small video camera is inserted in one incision to show the heart, while the surgeon uses remote-controlled surgical instruments to do the surgery. A heart-lung bypass machine is sometimes used during this procedure." } ]

[ { "from": "human", "value": "What are the risks of coronary artery bypass grafting?" }, { "from": "gpt", "value": "Although complications from coronary artery bypass grafting (CABG) are uncommon, the risks include:\nWound infection and bleeding.\nReactions to anesthesia.\nFever.\nPain.\nStroke, heart attack, or even death.\nSome patients develop a fever associated with chest pain, irritability, and decreased appetite. This is due to inflammation involving the lung and heart sac. This complication sometimes is seen 1 to 6 weeks after surgeries that involve cutting through the pericardium (the outer covering of the heart). This reaction usually is mild. However, some patients may develop fluid buildup around the heart that requires treatment. Memory loss and other changes, such as problems concentrating or thinking clearly, may occur in some people. These changes are more likely to occur in people who are older, who have high blood pressure or lung disease, or who drink excessive amounts of alcohol. These side effects often improve several months after surgery. Use of a heart-lung bypass machine increases the risk of blood clots forming in your blood vessels. Clots can travel to the brain or other parts of the body and block the flow of blood, which may cause a stroke or other problems. Recent technical improvements in heart-lung bypass machines are helping reduce the risk of blood clots forming. In general, the risk of complications is higher if CABG is done in an emergency situation (for example, during a heart attack), if you're older than 70, or if you have a history of smoking. Your risk also is higher if you have other diseases or conditions, such as diabetes, kidney disease, lung disease, or peripheral arterial disease." } ]

Your heart rate, blood pressure, and oxygen levels will be checked regularly during this time. An intravenous line (IV) will likely be inserted into a vein in your arm. Through the IV line, you may get medicines to control blood circulation and blood pressure. You also will likely have a tube in your bladder to drain urine and a tube to drain fluid from your chest. You may receive oxygen therapy (oxygen given through nasal prongs or a mask) and a temporary pacemaker while in the ICU. A pacemaker is a small device that's placed in the chest or abdomen to help control abnormal heart rhythms. Your doctor may recommend that you wear compression stockings on your legs as well. These stockings are tight at the ankle and become looser as they go up the leg. This creates gentle pressure up the leg. The pressure keeps blood from pooling and clotting. While in the ICU, you'll also have bandages on your chest incision (cut) and on the areas where an artery or vein was removed for grafting. After you leave the ICU, you'll be moved to a less intensive care area of the hospital for 3 to 5 days before going home.\nYour doctor will give you specific instructions for recovering at home, especially concerning:\nHow to care for your healing incisions.\nHow to recognize signs of infection or other complications.\nWhen to call the doctor right away.\nWhen to make followup appointments.\nYou also may get instructions on how to deal with common side effects from surgery. Side effects often go away within 4 to 6 weeks after surgery, but may include:\nDiscomfort or itching from healing incisions.\nSwelling of the area where an artery or vein was removed for grafting.\nMuscle pain or tightness in the shoulders and upper back.\nFatigue (tiredness), mood swings, or depression.\nProblems sleeping or loss of appetite.\nConstipation.\nChest pain around the site of the chest bone incision (more frequent with traditional CABG).\nFull recovery from traditional CABG may take 6 to 12 weeks or more. Less recovery time is needed for nontraditional CABG. Your doctor will tell you when you can start physical activity again. It varies from person to person, but there are some typical timeframes. Most people can resume sexual activity within about 4 weeks and driving after 3 to 8 weeks. Returning to work after 6 weeks is common unless your job involves specific and demanding physical activity. Some people may need to find less physically demanding types of work or work a reduced schedule at first.\nCare after surgery may include periodic checkups with doctors. During these visits, tests may be done to see how your heart is working. Tests may include EKG (electrocardiogram), stress testing, echocardiography, and cardiac CT. CABG is not a cure for coronary heart disease (CHD). You and your doctor may develop a treatment plan that includes lifestyle changes to help you stay healthy and reduce the chance of CHD getting worse. Lifestyle changes may include making changes to your diet, quitting smoking, doing physical activity regularly, and lowering and managing stress. Your doctor also may refer you to cardiac rehabilitation (rehab). Cardiac rehab is a medically supervised program that helps improve the health and well-being of people who have heart problems. Rehab programs include exercise training, education on heart healthy living, and counseling to reduce stress and help you return to an active life. Doctors supervise these programs, which may be offered in hospitals and other community facilities. Talk to your doctor about whether cardiac rehab might benefit you. Taking medicines as prescribed also is an important part of care after surgery. Your doctor may prescribe medicines to manage pain during recovery; lower cholesterol and blood pressure; reduce the risk of blood clots forming; manage diabetes; or treat depression." } ]

[ { "from": "human", "value": "What Procedure to Choose?" }, { "from": "gpt", "value": "Although many indications are the same for performing either PCI or CABG, these two procedures have inherently different mechanisms. While PCI mitigates an obstruction, it can not prevent plaque progression or rupture in other involved segments of the artery. On the contrary, CABG is able to prevent future ischemic insults caused by plaque progression or rupture in other involved segments of the artery. Most studies report the same outcome with PCI and CABG, but there are some reports that favor CABG over PCI: The SYNTAX trial with 705 patients demonstrated a significantly higher rate of major adverse cardiovascular events and mortality rate among those who received PCI than the CABG cohort. Two Studies reported that CABG is more effective in prevention of late spontaneous MI when compared to PCI. ACA 2021 revascularization guideline recommends to consider the following factors to decide whether to chose PCI or CABG: SYNTAX Score SYNTAX score derived from a clinical trial with the same name which predicts the grade of the anatomic complexity and can be used as a decision-making tool. This score is a guide for selection of a revascularization procedure in patients with multivessel coronary artery disease. All cause mortality rate among patients with a coronary artery disease -associated SYNTAX score equal or greater than 33 were significantly lower when undergone CABG than PCI For patients with SYNTAX score lower than 33, no differences have been report in mortality rate of CABG and PCI Compliance to medications Preferences of patient Individual factors, such as anatomic complexity, which is discussed in the following table: \n\n\nPCI would help patients with STEMI and ischemic symptoms for less than 12 hours. Rescue PCI is recommended for STEMI patients who failed re-perfusion after fibrinolytic therapy to improve the survival. PCI has been related to improved survival rate when done in STEMI patients who are stable and presented 12 to 24 hours after symptom onset. Regardless of time from MI, PCI can increase survival in STEMI patients who developed complications such as ongoing ischemia, acute sever heart failure, or life-threatening cardiac arrhythmia. Performing the PCI is not beneficial in stable and asymptomatic STEMI patients who have a totally occluded infarct artery >24 hours after symptom onset with no evidence for sever ischemia. The role of PCI in asymptomatic STEMI patients who are presenting after 12 to 24 hours after symptom onset is not well studied. However, based on a small trial named BRAVE-2 a reduction in left ventricular infarct size has been reported among asymptomatic STEMI patients who were treated with an invasive strategy of coronary stent within 12 to 48 hours after symptom onset, compared to conservative therapies. Both PCI and CABG are indicated in patients with STEMI, cardiogenic shock, and hemodynamic instability. CABG is recommended for patients with STEMI who have mechanical complications such as ventricular septal rupture, mitral regurgitation because of papillary muscle infarction or rupture, or free wall rupture. Emergent or urgent CABG is recommended in STEMI patients whose PCI is not feasible with a large area of myocardial involvement. On the other hand, emergent or urgent CABG should be avoided in these patients in the absence of ischemia or large myocardial involvement. Furthermore, CABG is usually avoided if patients' distal targets are poor. The following algorithm demonstrates the proper revascularization in STEMI patients. \n\n\nThe sole condition that fibrinolytic therapies are superior to PCI is when the duration from hospital presentation to PCI is anticipated to be more than 120 minutes. An early revascularization strategy could increase the survival rate in patients with STEMI complicated by cardiogenic shock.\nFractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are commonly used to assess the lesion significant. Fractional flow reserve (FFR) compares the maximal blood flow distal to the lesion to the normal maximal blood flow. On the other hand iFR compares the instantaneous wave-free ratio of the coronary pressure distal to the lesion during the diastole with the aortic pressure. Reported in numbers of trials which used FFR, FFR -guided PCI was successful in lowering the revascularization rate, procedure-related chest pain in patients with stable coronary artery disease and functionally significant stenosis. In one of these trials patients with abnormal FFR significantly benefited from PCI over medical therapy with lower rate of ischemia -driven revascularization and shorter procedural time. FFR -guided revascularization with CABG was more off-pump with fewer anastomosis and simpler procedure compared to CABG with angiogram -guided revascularization in one of the clinical trials. Although other studies reported similar outcomes in both. iFR measure does not require the administration of adenosine has been also studied in clinical trials. Results supported that this measure is not inferior to FFR and also showed less adverse outcome related to the procedure. Lower rate of long-term major adverse cardiac events has been reported when PCI was deferred with FFR greater than 0.80 or iFR that is >0.89. One of the trials named DEFER (Deferral of Percutaneous Intervention) reported that the rate of adverse outcome cardiac outcomes is similar in both group of patients whose PCI has been deferred either with a FFR greater than 0.75 or intermediate angiographic measures." } ]

[ { "from": "human", "value": "How a coronary risk profile performed?" }, { "from": "gpt", "value": "Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood. Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.\nIn infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.\nThe blood is sent to a laboratory, where the following are measured:\nLow density lipoprotein (LDL or \"bad\" cholesterol) High density lipoprotein (HDL or \"good\" cholesterol) Total cholesterol Triglycerides Very low density lipoprotein (VLDL cholesterol, though this is often calculated from the triglyceride level) Other blood tests, such as C-reactive protein (CRP), may be added to the profile in some laboratories." } ]
