Heart failure, also called congestive heart failure, is a condition in which the heart can no longer pump enough blood to the rest of the body.

"Heart failure" is a broad term—often used inter-changeably with "congestive heart failure" (CHF)—to describe the heart's inability to consistently pump enough blood to the body's organs and tissues. Heart failure occurs either from a structural o...

Heart failure is a condition in which the heart has lost the ability to pump enough blood to the body's tissues. With too little blood being delivered, the organs and other tissues do not receive enough oxygen and nutrients to function properly.

Hypertension is the term used to describe high blood pressure. Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as two numbers. For example, 120 over 80 (written as 120/80 mmHg. The top number is your systoli...

Blood pressure is the force with which blood pushes against the artery walls as it travels through the body. Like air in a balloon, blood fills arteries to a certain capacity—and just as too much air pressure can cause damage to a balloon, too muc...

In populations, blood pressures fit a normal distribution, but the attendant risks of heart disease and stroke increase curvilinearly with increasing levels of blood pressure, without any obvious breakpoint ( Fig. 63-1 ). Thus, the separation of normal from high blood pressure is arbitrary, and the definition of hypertension has been a moving target.

Also known as high blood pressure, a condition in which too much force is exerted by the blood as it travels through the body's arteries. There are two types of hypertension: primary and secondary. Primary, or essential, hypertension is caused by ...

Hypertension is an independent risk factor for coronary artery disease (CAD) and stroke, leading causes of morbidity and mortality in North America. Concern has been raised that there is inadequate outpatient detection, evaluation, and treatment of hypertension, and that this is resulting in increased hospital admissions with complications of untreated hypertension: heart failure, and end-stage renal disease .

The National High Blood Pressure Education Program (NHBPEP) was established in 1972 by the National Institute of Health to translate research results on the health hazards of high blood pressure into clinical and public health practice. Before 190...

Coronary heart disease (CHD) is a narrowing of the small blood vessels that supply blood and oxygen to the heart. CHD is also called coronary artery disease. See also: Angina; Heart attack; Unstable angina.

Coronary artery disease is a narrowing or blockage of the arteries and vessels that provide oxygen and nutrients to the heart. It is caused by atherosclerosis , an accumulation of fatty materials on the inner linings of arteries. The resulting blo...

Coronary artery disease is a stenosis (narrowing) or blockage of the arteries and vessels that provide oxygenated blood to the heart . It is caused by atherosclerosis (hardening of the arteries), an accumulation of fatty plaque on the inner lining...

The heart, a powerful muscle that beats over 50,000 times in one day, is fed the blood and energy it needs through small tubes called coronary arteries (see Figure 1). Coronary artery disease (CAD) is the most common cause of death and disability ...

The aorta is the main artery leaving the heart. When blood leaves the heart, it flows from the lower chamber (the left ventricle), through the aortic valve, into the aorta. In aortic stenosis, the aortic valve does not open fully. This restricts b...

Mitral stenosis is a heart valve disorder that involves the mitral valve. This valve separates the upper and lower chambers on the left side of the heart. Stenosis refers to a condition in which the valve does not open fully, restricting blood flow.

The term stenosis means an abnormal narrowing of an opening. Mitral valve stenosis refers to a condition in the heart in which one of the valve openings has become narrow and restricts the flow of blood from the upper left chamber (left atrium) to...
