History of Heart Disease

History of Heart Disease involves Coronary Artery Diseasesbecause these disorders are the primary cause of Heart disorders.


The heart is the pumping machine of the body that enables the blood to reach every part of the body. Every organ needs blood to replenish the oxygen supply in them and that won’t exclude the heart itself. The heart also has its own blood supply through the Coronary Arteries.

What are Coronary Arteries?

The Coronary Arteries are the passageways of the blood to the heart tissues. Akin to other organs and tissues in the body, the heart also needs oxygenated blood to function at its best and deoxygenated blood should as well carry away from the tissues. The Coronary Arteries compose of two major arteries; the left and right coronary arteries.

The system of the left coronary artery branches into the left anterior descending and circumflex arteries.  They supply blood to the left atrium and left ventricle. The system of the right coronary artery divides into the acute marginal and right posterior descending arteries which are responsible to supply blood to the right atrium, right ventricle, SA node or Sinoatrial node (regulates the rhythm rate of the heart consists of a cluster of cells), and AV node or Atrioventricular node.

Supplementary arteries divide off the left major coronary artery to provide the left portion of the heart tissues with oxygenated blood. It involves the Circumflex Artery or Cx, this artery originates from the left coronary artery and circumscribe the heart muscle which supplies blood to the tangential side and the backside of the heart. The LAD or Left Anterior Descending Artery originates from the left coronary artery and provides blood to the front potion of the heart’s left side.

The Coronary Arteries deliver oxygenated blood to the heart tissues; therefore, if there is any disorder concerning the coronary arteries then it would project serious complications due to the reduced blood flow of nutrients and oxygen to the heart. This History of Heart Disease can lead to a heart arrest and probably death.

What is Coronary Atherosclerosis?

The most common History of Heart Disease is Atherosclerosis. It is the anomalous accumulation of fatty or lipid materials and fibrous tissues in the lumen wall of the arterial blood vessels. This accumulation of substances can produce a blockage or narrows down the coronary arteries in a way; reducing the blood supply to the muscle portion of the heart, the myocardium.

Heart Disease Information that are based from researches identified that this condition is associated to the recurrent inflammatory response of the body to injuries to the artery wall and succeeding alterations in the biochemical and structural characteristics of the arterial walls.

Atherosclerosis is proven to begin with the deposition of fatty streaks of lipid substances in the arterial intimae wall. These lesions can typically begin during childhood, probably even in early years of life. However, not every single fatty streak can develop into advanced lesions. Environmental and genetic aspects are necessary for the progression of the said lesions.

An injury to the vascular endothelium occurs due to hypertension, smoking and other factors. This activates the inflammatory response that enables the macrophages to infiltrate the damaged vascular endothelium which later on ingests the lipids (turns into foam cells which can attract platelets to initiate its clotting mechanisms).

What Causes Heart Disease is the occurrence of this condition, when the vessel walls has its smooth muscle cells subsequently thrive and create a fibrous cap over a central part filled with lipid and inflammatory permeates. These set down of lipids is called atheromas. If the cap is lean and inflammation is continuing, the core may increase its size causing it to burst and form a thrombus. The thrombus will then occlude the blood flow causing the abrupt cardiac fatality or an acute Myocardial Infarction.

What are the Symptoms of Coronary Artery Disorder?

Coronary Artery Atherosclerosis produces manifestations and complications consistent with the degree and location of the arterial lumen narrowing, formation of thrombus, and occlusion of the blood supply to the myocardium. This hindrance to blood supply is typically progressive, resulting to insufficient blood flow that divests the heart muscles of oxygen necessary for its survival.

The History of Heart Disease can manifest common symptoms that are related to the disruptions in the heart’s arteries such as chest pressure or pain, rapid breathing, difficulty of breathing, drooping of muscles, numbness in the legs and arms, arm pain, leg pain, and shoulder pain. Serious manifestations may be a sign of a life threatening situation. In some instances, atherosclerosis can be detrimental and needs immediate care. This symptom involves blurring or double vision, altered level of consciousness (fainting or unresponsiveness), dysphagia (difficulty in swallowing), paralysis of the other parts of the body, tachycardia (rapid heart rate), and severe back ache. The most frequent symptom of myocardial ischemia is the acute onset of chest pain, termed as Angina Pectoris.
