The strongest muscle in the body is the heart, beating about 70 times a minute 100, 000 times a day. The average heart beats about 2.5 billion times in a 70-year lifetime.
Your body’s functioning depends on the proper circulation of blood. The heart and blood vessels deliver oxygen and nutrients to the body’s cells. The heart’s continuous rhythmic contraction and relaxation helps circulate the blood.
The term “heart failure” is a progressive disorder where the heart is not pumping blood as it should, which results in damage to the cardiovascular system. Sometimes, the heart cannot pump enough blood through the body, does not pump blood with enough force, or cannot fill with enough blood.
“Heart failure” does not mean your heart is about to stop working or has stopped completely, rather, that the heart is not pumping correctly to adequately nourish the body. Heart failure is a serious medical condition that requires serious treatment.
Heart Failure
Heart failure occurs when the heart no longer functions as an adequate pump. Any condition causing progressive weakening and damage to the heart may cause heart failure.
Blood pressure is the force of the blood flowing through the arteries. High blood pressure, also known as hypertension, forces the heart to work harder than it should to pump blood throughout your body. This extra work by the heart muscle may result in the heart thickening and enlarging, to compensate for this added effort. Over an extended period, the heart may stiffen or weaken, and eventually lose its ability to pump effectively. High blood pressure, along with coronary artery disease (CAD), and diabetes are the three leading contributors to heart failure.
Coronary artery disease (CAD), also known as coronary heart disease (CHD) is a condition when the coronary arteries, which carry oxygen-rich blood to the heart muscle, gradually become coated, narrowed, and clogged by a fatty substance called plaque. This combination of fat, calcium, and cholesterol deposits restricts normal, healthy blood flow. This condition is likely to create blood clots, which may severely limit or completely stop the flow of blood. Narrowed arteries result in a lack of blood supply to the heart and may produce chest pain (angina), damage to the heart muscle (cardiomyopathy), a heart attack (myocardial infarction), or death. A previous heart attack may produce scar tissue in the heart muscle, creating more obstacles, which further interfere with healthy blood flow. Infections, alcohol abuse, a bad reaction to drugs, and diseases of the body also damage the heart. Genetic birth defects, injury to the heart at delivery, and a physical accident are additional reasons for heart damage.
Additional contributing factors to heart failure include congenital heart defects, structural defects in the heart, valves, and chambers, and arrhythmias – abnormal heart rhythms that may result in the heart beating too fast. Conversely, a slower heartbeat may not allow the heart to pump an adequate supply of blood to reach the body. Compensating for these insufficiencies, the heart may weaken over time, which may also lead to heart failure. Myocarditis, a viral infection that causes an inflammation of the heart muscle, may result in left-sided heart failure.
