Most people who take a drug test take a presumptive test, cheaper and faster than other methods of testing. However, it is less accurate and can render false results. The FDA recommends for confirmatory testing to be conducted and the placing of a warning label on the presumptive drug test: "This assay provides only a preliminary result.
The so-called "classical 3-point MACE" is defined as a composite of nonfatal stroke, nonfatal myocardial infarction, and cardiovascular death. [4] [5] Another study similarly defined MACE as a composite of nonfatal stroke, nonfatal acute coronary syndrome, and death from vascular causes. [6]
In particular, acute myocardial infarction in the distribution of the circumflex artery is likely to produce a nondiagnostic ECG. [10] The use of additional ECG leads like right-sided leads V3R and V4R and posterior leads V7, V8, and V9 may improve sensitivity for right ventricular and posterior myocardial infarction.

Acute coronary syndrome (ACS) is a syndrome due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. [1] The most common symptom is centrally located pressure-like chest pain, often radiating to the left shoulder [2] or angle of the jaw, and associated with nausea and sweating.
Coronary "microembolization" is being explored as a focal point for coronary thrombus formation and subsequent sudden death due to acute myocardial infarction. [6] High mobility group box-1 (HMGB-1) proteins as important mediators in thrombus formation. [7] Coronary sinus thrombosis as a severe complication after procedures. [8]
Anticoagulants in acute coronary syndrome are targeted against the coronary blood clot, as well as towards prevention of thrombotic complications, like formation of blood clots in the ventricles, stroke, pulmonary embolism or deep vein thrombosis. [49] Patients undergoing PCI also need an anticoagulant to prevent catheter thrombosis.
Coronary fatty streaks can begin to form in adolescence. [31] It is estimated that 82 percent of people who die of coronary heart disease are 65 and older. [32] Simultaneously, the risk of stroke doubles every decade after age 55. [33] Multiple explanations are proposed to explain why age increases the risk of cardiovascular/heart diseases.
In case of a vulnerable plaque, this results in a larger diameter of the Artery Lumen, which means that patient's life style is not affected, however, when the thin fibrous cap breaks, this causes a prompt activation of platelets which causes the occlusion of the artery, which causes a sudden heart attack if it occurs in the coronary artery.
