This is a list of countries ranked by the quality of healthcare, as published by the Organisation for Economic Co-operation and Development (). [1] The ranking takes into account various health outcomes, including survival rates for seven types of cancer, as well as for strokes and heart attacks.
The Seven Countries Study suggested that the risk and rates of heart attack and stroke (CVR), both at the population level and at the individual level, correlated directly and independently to the level of total serum cholesterol, in seven sampled out countries. It demonstrated that the correlation between blood cholesterol level and coronary ...
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease ...
In 2021, the American Heart Association clarified that "heart attack" is often mistakenly used to describe cardiac arrest. While a heart attack refers to death of heart muscle tissue as a result of blood supply loss, cardiac arrest is caused when the heart's electrical system malfunctions. Furthermore, the American Heart Association explains ...
Myocardial infarction; Other names: Acute myocardial infarction (AMI), heart attack: A myocardial infarction occurs when an atherosclerotic plaque slowly builds up in the inner lining of a coronary artery and then suddenly ruptures, causing catastrophic thrombus formation, totally occluding the artery and preventing blood flow downstream to the heart muscle.
The Roseto effect is the phenomenon by which a close-knit community experiences a reduced rate of heart disease. The effect is named for Roseto, Pennsylvania.The Roseto effect was first noticed in 1961 when the local Roseto doctor encountered Stewart Wolf, then head of Medicine of the University of Oklahoma, and they discussed, over a couple of beers, the unusually low rate of myocardial ...
Also known as 'effort angina', this refers to the classic type of angina related to myocardial ischemia.A typical presentation of stable angina is that of chest discomfort and associated symptoms precipitated by some activity (running, walking, etc.) with minimal or non-existent symptoms at rest or after administration of sublingual nitroglycerin.

The initial heart rhythm is most often ventricular fibrillation. [55] The diagnosis is confirmed by finding no pulse. [53] While a cardiac arrest may be caused by heart attack or heart failure these are not the same. [52] Prevention includes not smoking, physical activity, and maintaining a healthy weight. [56]
