What Causes Heart Blockage?

The heart consists of four chambers: there are two at the top called the atria and two at the bottom known as the ventricles. The heart has its own pace maker called the sinoatrial (SA) node which is a small mass of specialized cells in the heart’s right atrium. The sinus node produces electrical pulses which make the heart beat. A distinct signal travels from the sinus node down to the ventricles passing through a specialized conducting tissue called the atrioventricular (AV) node. This process...

Valvular Heart Disease

Definition Valvular heart disease is a disease that affects at least one or more of the valves within the heart. The heart maintains four types of valves: the pulmonary and tricuspid valves on the left and the aortic and mitral valves on the right. The valves are located at the opening of each heart chamber and allows one directional movement of blood. When the valves malfunction it may cause the blood to flow incorrectly resulting in leakage from the valve(s) and poor circulation. Valvular disease...

What Causes Heart Failure?

heThe “inability of the heart to pump enough blood to sustain normal bodily functions” is known as Heart Failure. It occurs when the heart doesn’t have sufficient blood, when it is unable to pump enough blood to the rest of the body, or a combination of both. A person that has heart failure will still have a working heart; however, they must seek medical attention. Heart failure is a common condition that occurs over a period of time as the heart is weakened by other heart diseases and health...

Symptoms of Congestive Heart Failure

Marked by the incapacity of the heart to supply sufficient flow of blood to the body, congestive heart failure is a life-threatening medical condition caused by a weakened state of the heart. Some of the contributory factors include chronic heart problems like heart arrhythmias, congenital heart defects and myocarditis. Other possible causes include severe heart muscle damage or cardiomyopathy, high blood pressure and coronary artery disease. People can understand this severe health problem by...

Heart Stent Pain

Together with angioplasty, the use of stents or stenting is a common medical procedure performed on patients suffering from atherosclerosis, a disease marked by obstructed or narrowed blood vessels. Heart stent is classified into two major types, namely drug-eluting stent and bare-metal stent. Although it has been proven effective in many cases, its use has certain drawbacks and disadvantages, affecting mainly the upper, lower, left and right parts of the chest. To know more about heart stent pain,...

Ischaemic Heart Disease

Ischaemic heart disease is a condition in which the heart is not satisfactorily supplied with blood resulting in damage to the heart muscle. Ultimately, the heart muscle operates poorly over time. The disease is attributed to accumulation of plaque in the arteries which results in the narrowing of the vessels and the subsequent reduction in the supply of blood to the heart. It is considered the most common cause of death in the United States and other western countries. Read more

Symptoms of Coronary Blocked Arteries

A severe medical condition that has a great impact on the heart, patients suffering from coronary blocked arteries must be given utmost care right away. Coronary arteries and blood vessels are blocked due to build up of high levels of cholesterol and fats. When the blood flow is limited, vital nutrients and oxygen are unable to reach the various organs and tissues of the body. People can find out more about this medical condition by understanding the diagnosis, treatments and symptoms of coronary...

Cerebrovascular Disease

This is a group of brain dysfunctions relating to the disease of vascular tubes (blood vessels) supplying the brain. This disease is known primarily to affect elderly persons; however due the nature of the disease it can affect anyone if care is not taken to be healthy. Changes in the design of the blood vessels may make them narrow, stiff, deformed amongst other deformations, these changes in the blood vessels result in increased blood pressure in the brain since they vessels get narrower, which...
