Heart Attack: Causes and Symptoms
Medically known as myocardial infarction or acute myocardial infarction, heart attack has become one of the most common medical anomalies happening in the human body in recent times. In easy terms, a heart attack occurs when a certain part of the heart gets deprived of proper blood supply, due to blockages that occur in the blood supplying arteries. As a result of not getting enough of the blood that provides oxygen to the cardiac muscles, the muscles get severely damaged or even dies, leading to abnormal functioning of the cardiac muscles.
The consequences are severely impactful. Improper oxygenation of the cardiac muscles leads to the cardiac cells not being supplied with enough of oxygen. As a result, the cells cannot function to their fullest strength, and the cardiac muscles become weaker. This leads to scant pumping of blood to the rest of the body by the heart, and this leads to a plethora of symptoms, the most common being the chest ache on the left side that gradually move towards the neck, shoulders, arms, and back regions. Usually, the pain stretches on for over fifteen minutes, the real intensity and duration of the pain depending on the nature of the blockages in the coronary arteries. Other symptoms that often accompany chest pains include vomiting, nausea, dizziness, shortness of breath and sweating.
There are various causes from which heart attacks may be induced. Leading the list is the irregular lifestyle and living habits of the present generation. Irregular styles of eating, coupled with a growing population of drinkers and smokers, and a flourishing habit of frequent fine dining and late night parties have led to a growing intake of cholesterols and certain harmful fats into our dietary system. With food connoisseurs pulling out all stops in the kitchen to bring out more exotic dishes, fine dining often becomes too much of a good thing if people opt for its glory on a regular basis. Hard-cooked food leads to deposit of extra fat and cholesterol in the arteries. As these are non-soluble fats, they cannot be broken down easily by our metabolism system, and with gradual passage of time, they get deposited as a solid mass of impermeable molecules. A blockage can be confidently detected by medical ways only when the blood flow faces significant difficulty in passage through the arteries. Cardiologists may use physical exercise stress reports, or in more severe cases a more procedural angiography, to detect the heart anomaly and find out the extent of blockage in the cardiac arteries. Electrocardiograms (ECGs) have also been put to regular use to monitor and detect the cardiac conditions.
Other causal factors for a heart attack include hyper-tension, diabetes, high blood pressure, and severe physical exertion. A high blood pressure, when coupled with excessive psychological stress, leads to a lot of stress on the walls of the cardiac muscles, as a result of which there is extensive damage done to the cardiac muscles. It is for this reason that aged people (especially men) are more prone to suffering an ischemic heart disease at any moment of heated argument. A heart attack, however, can be avoided by following a few simple steps: a regular diet, controlled or no smoking and drinking, and a relative peace of mind.
