How many cigarettes per day increase the risk of a heart attack? | Context: Tobacco smoking (including secondhand smoke) and short-term exposure to air pollution such as carbon monoxide, nitrogen dioxide, and sulfur dioxide (but not ozone) have been associated with MI. Other factors that increase the risk of MI and are associated with worse outcomes after an MI include lack of physical activity and psychosocial factors including low socioeconomic status, social isolation, and negative emotions. Shift work is also associated with a higher risk of MI. Acute and prolonged intake of high quantities of alcoholic drinks (3-4 or more) increase the risk of a heart attack..

Evidence for what product has proven to be unequivocally dangerous? | Context: The evidence for saturated fat is unclear. Some state there is evidence of benefit from reducing saturated fat, specifically a benefit from eating polyunsaturated fat instead of saturated fat. While others state there is little evidence that reducing dietary saturated fat or increasing polyunsaturated fat intake affects heart attack risk. Dietary cholesterol does not appear to have a significant effect on blood cholesterol and thus recommendations about its consumption may not be needed. Trans fats do appear to increase risk..

How many genetic variants are shown to decrease risk of an MI? | Context: Genome-wide association studies have found 27 genetic variants that are associated with an increased risk of myocardial infarction. Strongest association of MI has been found with the 9p21 genomic locus, which contains genes CDKN2A & 2B, although the single nucleotide polymorphisms that are implicated are within a non-coding region. The majority of these variants are in regions that have not been previously implicated in coronary artery disease. The following genes have an association with MI: PCSK9, SORT1, MIA3, WDR12, MRAS, PHACTR1, LPA, TCF21, MTHFDSL, ZC3HC1, CDKN2A, 2B, ABO, PDGF0, APOA5, MNF1ASM283, COL4A1, HHIPC1, SMAD3, ADAMTS7, RAS1, SMG6, SNF8, LDLR, SLC5A3, MRPS6, KCNE2..

How many subtypes does ST-elevated MI have? | Context: Acute myocardial infarction refers to two subtypes of acute coronary syndrome, namely non-ST-elevated and ST-elevated MIs, which are most frequently (but not always) a manifestation of coronary artery disease. The most common triggering event is the disruption of an atherosclerotic plaque in an epicardial coronary artery, which leads to a clotting cascade, sometimes resulting in total occlusion of the artery. Atherosclerosis is the gradual buildup of cholesterol and fibrous tissue in plaques in the wall of arteries (in this case, the coronary arteries), typically over decades. Bloodstream column irregularities visible on angiography reflect artery lumen narrowing as a result of decades of advancing atherosclerosis. Plaques can become unstable, rupture, and additionally promote the formation of a blood clot that occludes the artery; this can occur in minutes. When a severe enough plaque rupture occurs in the coronary arteries, it leads to MI (necrosis of downstream myocardium). It is estimated that one billion cardiac cells are lost in a typical MI..

What does necrosis trigger? | Context: If impaired blood flow to the heart lasts long enough, it triggers a process called the ischemic cascade; the heart cells in the territory of the occluded coronary artery die (chiefly through necrosis) and do not grow back. A collagen scar forms in their place. Recent studies indicate that another form of cell death, apoptosis, also plays a role in the process of tissue damage following an MI. As a result, the person's heart will be permanently damaged. This myocardial scarring also puts the person at risk for potentially life-threatening abnormal heart rhythms (arrhythmias), and may result in the formation of a ventricular aneurysm that can rupture with catastrophic consequences..

Normal heart tissue is slower than what? | Context: Injured heart tissue conducts electrical impulses more slowly than normal heart tissue. The difference in conduction velocity between injured and uninjured tissue can trigger re-entry or a feedback loop that is believed to be the cause of many lethal arrhythmias. The most serious of these arrhythmias is ventricular fibrillation (V-Fib/VF), an extremely fast and chaotic heart rhythm that is the leading cause of sudden cardiac death. Another life-threatening arrhythmia is ventricular tachycardia (V-tach/VT), which can cause sudden cardiac death. However, VT usually results in rapid heart rates that prevent the heart from pumping blood effectively. Cardiac output and blood pressure may fall to dangerous levels, which can lead to further coronary ischemia and extension of the infarct.. Answer: {'text': [], 'answer_start': []}. Question: |

The setting of plaque is called what? | Context: Myocardial infarction in the setting of plaque results from underlying atherosclerosis. Inflammation is known to be an important step in the process of atherosclerotic plaque formation. C-reactive protein (CRP) is a sensitive but nonspecific marker for inflammation. Elevated CRP blood levels, especially measured with high-sensitivity assays, can predict the risk of MI, as well as stroke and development of diabetes. Moreover, some drugs for MI might also reduce CRP levels. The use of high-sensitivity CRP assays as a means of screening the general population is advised against, but it may be used optionally at the physician's discretion in those who already present with other risk factors or known coronary artery disease. Whether CRP plays a direct role in atherosclerosis remains uncertain.. Answer: {'text': [], 'answer_start': []}. Question: |

What is used to examine blood flood in unstable patients? | Context: In stable patients whose symptoms have resolved by the time of evaluation, technetium (99mTc) sestamibi (i.e. a "MIBI scan") or thallium-201 chloride can be used in nuclear medicine to visualize areas of reduced blood flow in conjunction with physiological or pharmacological stress. Thallium may also be used to determine viability of tissue, distinguishing whether nonfunctional myocardium is actually dead or merely in a state of hibernation or of being stunned. Medical societies and professional guidelines recommend that the physician confirm a person is at high risk for myocardial infarction before conducting imaging tests to make a diagnosis. Patients who have a normal ECG and who are able to exercise, for example, do not merit routine imaging.

A patient does not need routine imaging when they have what kind of biomarker? | Context: In stable patients whose symptoms have resolved by the time of evaluation, technetium (99mTc) sestamibi (i.e. a "MIBI scan") or thallium-201 chloride can be used in nuclear medicine to visualize areas of reduced blood flow in conjunction with physiological or pharmacological stress. Thallium may also be used to determine viability of tissue, distinguishing whether nonfunctional myocardium is actually dead or merely in a state of hibernation or of being stunned. Medical societies and professional guidelines recommend that the physician confirm a person is at high risk for myocardial infarction before conducting imaging tests to make a diagnosis. Patients who have a normal ECG and who are able to exercise, for example, do not merit routine imaging. Imaging tests such as stress radionuclide myocardial perfusion imaging or stress echocardiography can confirm a diagnosis when a patient's history, physical exam, ECG, and cardiac biomarkers suggest the likelihood of a problem..

How many mg of fat is suggested for a healthy person's diet? | Context: There is some controversy surrounding the effect of dietary fat on the development of cardiovascular disease. People are often advised to keep a diet where less than 30% of the energy intake derives from fat, a diet that contains less than 7% of the energy intake in the form of saturated fat, and a diet that contains less than 300 mg/day of cholesterol. Replacing saturated with mono- polyunsaturated fat is also recommended, as the consumption of polyunsaturated fat instead of saturated fat may decrease coronary heart disease. Olive oil, rapeseed oil and related products are to be used instead of saturated fat.. Answer: {'text': [], 'answer_start': []}. Question: |

What enzymes in the body typically destroy blood clots? | Context: Thrombolysis involves the administration of medication that activates the enzymes that normally destroy blood clots. Thrombolysis agents include streptokinase, reteplase, alteplase, and tenecteplase.

What is a myocardial infarction is always considered to be? | Context: At common law, in general, a myocardial infarction is a disease, but may sometimes be an injury.
