Heart disease and stroke are mainly consequences of atherosclerosis and high blood pressure (hypertension). Heart disease is sometimes included in the broader category of atherosclerotic and hypertensive diseases. Risk factors for heart disease and stroke have been well established for many years. Distinct from age, family history, and possible genetic determinants are modifiable risk factors that cause heart attacks and strokes, including high blood cholesterol, high blood pressure, smoking, and diabetes. Behaviors that contribute to development of risk factors for heart disease, partly by causing obesity, include adverse dietary patterns and physical inactivity.

Social and environmental conditions that may determine such behavioral patterns, in turn, include education and income, cultural influences, family and personal habits, and opportunities to make favorable choices.For example, dietary patterns result from the influences of food production policies, marketing practices, product availability, cost, convenience, knowledge, choices that affect health, and preferences that are often based on early-life habits. Because many aspects of behavior are clearly beyond the control of the individual, the scope of heart disease and Stroke and stroke prevention, from the public health perspective, extends far beyond the individual or the patient. Thus, a comprehensive public health strategy for heart disease prevention must address the broader determinants of risk and disease burden as they affect both the population as a whole and particular groups of special concern, including those determinants that make healthier choices more likely for defeating heart disease.

coronary heart disease

Coronary artery disease (CAD) occurs when the arteries that supply blood to the heart muscle (coronary arteries) become hardened and narrowed. The arteries harden and become narrow due to the buildup of plaque on the inner walls or lining of the arteries (atherosclerosis). Blood flow to the heart is reduced as plaque narrows the coronary arteries. This decreases the oxygen supply to the heart muscle.

CAD is the most common type of heart disease. It is the leading cause of death in the U.S. in both men and women.

When blood flow and oxygen supply to the heart are reduced or cut off, you can develop:
  • Angina. Angina is chest pain or discomfort that occurs when your heart is not getting enough blood.

  • Heart attack. A heart attack happens when a blood clot suddenly cuts off most or all blood supply to part of the heart. Cells in the heart muscle that do not receive enough oxygen-carrying blood begin to die. This can cause permanent damage to the heart muscle.
Over time, CAD can weaken your heart muscle and contribute to:
  • Heart failure. In heart failure, the heart is not able to pump blood to the rest of the body effectively. Heart failure does not mean that your heart has stopped or is about to stop working. But it does mean that your heart is failing to pump blood the way that it should.

  • Arrhythmias. Arrhythmias are changes in the normal rhythm of the heartbeats. Some can be quite serious

Heart Attack Symtoms

The National Heart Attack Alert Program notes these major signs of a heart attack: Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts for more than a few minutes, or goes away and comes back. The discomfort can feel like uncomfortable pressure, squeezing, fullness, or pain.

  • Congenital Heart Disease - A Conundrum

    Heart is the most significant organ of the body. It controls and regulates the entire body. An individual can survive the loss of other organs of body but not of a heart. The moment heart ceases pumping blood to the body, it results in a heart stroke and there are chances that the person may die.

    But people are often negligent in taking care of this undeniably crucial organ of their body. This is made evident by the studies that reveal the escalating deaths due to cardiac arrests every year. It is not just the elderly who are gripped by cardiac seizures ...

  • The Truth About Red Wine and Heart Disease

    Red Wine, Heart Disease, Hungry Sharks and Knights in Shining Armor

    What is so special about wine? What is it that makes it potentially more protective against coronary heart disease, and perhaps other diseases, that other forms of alcohol?

    In recent years, scientists have concluded without doubt that many human diseases such as heart disease, cancer and the aging process is caused or stimulated by a ravenous group of chemicals called free radicals, that act like hungry sharks. These highly charged little villains prowl the body and attack healthy ...
