The History of Heart Disease is traced to many factors and Coronary Artery Diseases such as Atherosclerosis and Angina Pectoris. These two conditions specifically focus on these two conditions. It includes the definition of Coronary Arteries and its functions. These circumstances also include variety of signs and symptoms a person may exhibit during the course of the disease; the risk factors of having the condition; types of angina pectoris; and gerontologic concerns about these disorders.
The coronary arteries are the lifelines of every heart in a human body. These arteries supply blood which contains oxygen and nutrients. It consists of two main arteries which are termed as the left and right coronary arteries. The major arteries subdivide into supplementary or minor arteries that provide blood to the different structures of the heart. Without these arteries, the heart will die due to infarction or cell death. Disruptions on the heart’s functions will also occur when the presence of an occlusion is noted in one of these arteries. There would be an ischemia or blood deprivation in the heart muscles because of this occlusion.
Majority of the artery occlusion are associated with coronary atherosclerosis. Atherosclerosis is the unusual collection of fibrous membranes and lipid materials or fatty substances within the linings of arterial blood vessels. This collection of materials can create an occlusion that tapers down the size of the coronary arteries’ lumen. The decrease in size of the artery will result to the reduction of blood supply to the heart. Atherosclerosis can start from a simple atheroma then becomes a thrombus. This thrombus can dislodge from the artery wall and travels within the bloodstream to other parts of the body. Atherosclerosis can originate from the arteries of other parts of the body that may become an embolus which can get to the heart’s arteries.
The existence of an obstruction within the artery will give rise to certain manifestations. The Signs of Heart Disease can come about such as Angina Pectoris. This condition is regarded as a syndrome, an indication of an impeding heart attack. Angina Pectoris is characterized by chest pressure or pain. The quality of pain is described as crushing pain within the anterior portion of the chest. This syndrome may come along with other manifestations like lack of sensation in the arms and legs; arm, shoulder and leg pain; tachypnea and tachycardia.
These symptoms take place when the patient is experiencing emotional anxiety and physical force which can result to the increase in oxygen demand of the body. For diabetic patients, may have different form of symptoms due to incidence of complication of this disease on the patient, termed as neuropathy. They might only manifest numbness, diaphoresis, shortness of breath and chest pain may be absent for majority of patients with diabetes. Anxiety can take place in conjunction with angina because the patient will be preoccupied with the thought of an imminent myocardial infarction. The risk factors associated with the incidence of anginal pain. Persons with this syndrome are traced to experienced or undergone certain activities before the attack such as physical exertion, cold exposure, eating excessively and stressed out. The important factor of angina is that it is comforted by rest and nitroglycerin.
