Chronic heart failure is a complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood 49 systolic heart failure arises from a compromise in the contractility of the heart and is defined as a left ventricular ejection fraction of 45. Cardiovascular disease and hypertension—a recent study found that even modestly reduced sleep (six to seven hours per night) was associated with a greatly increased the risk of coronary artery calcification, a predictor of future myocardial infarction (heart attack) and death due to heart disease 6 there is also growing evidence of a.
The body is then able to use the oxygen in the blood to carry out its normal functions this blood will again return back to the heart through the veins and the cycle continues information on re-publishing of our images. Coronary heart disease (also known as coronary artery disease or ischemic heart disease) is a general term that describes conditions caused by an interrupted or diminished blood flow through the coronary arteries to the heart muscle. A cardiovascular examination will be performed to assess the heart function (eg for the presence of heart failure, valvular disease) and the presence of peripheral vascular disease the respiratory system will also be assessed to rule out lung diseases causing similar complaints ( chest pain , breathlessness .

It draws all its authority from its predictive and explanatory utility: against the background of assuming normal heart function, for example, we account for variation in actual hearts (a particular rhythm, say), by citing the textbook rhythmic pattern (which may be very unusual statistically) and identifying other patterns as arrhythmic.
