What is Myocardial infarction?
Myocardial infarction, or simply put, a heart attack occurs when the blood muscles supplying blood and oxygen to the heart begin to weaken and die due to a blood clot within one of the arteries carrying blood into the heart.
A blood clot in the arteries could occur at any time, and for a number of reasons; but when this occurs in the coronary artery supplying blood and oxygen to the heart, then there is a blockage of blood flow into the heart, and this portends danger of death to the individual concerned.
Any deprivation of oxygen and blood to the heart, such as that of a blood clot, can cause intense chest pains. If a condition like this is not medically addressed within a few hours, it could lead to death. What then are the causes of myocardial infarction and what are the symptoms to watch out for?
- Atherosclerosis: This condition is one of the top infarction causes heart disease cases. This generally occurs when there is hardening of the walls of the arteries and a resultant reduction in the lumen or channel size of the arteries in such way that blood cannot easily flow because the blood passage is narrowed down by cholesterol plaques. Explained another way, any collection of cholesterol could settle within the walls of the arteries where the blood flows through the ‘tubes’, and with this settlement of cholesterol, there could be a hardening of the walls of the arteries in such a way as to hamper the flow of blood and oxygen. This could cause pains and inflammations in parts of the body supplied by such arteries. That is, if it is the coronary arteries supplying blood to the heart that become hardened due to infarction causes, it could lead to myocardial infarction symptoms like chest pain and heart attacks.
- Angina pectoris: This is a condition where blood and oxygen is not being provided to the muscles of the heart in the required volumes; as such, this put an excessive load on the muscles and can cause failure. Since the heart beats and responds to increase in body activity, there will be infarction symptoms like angina or chest pain if the muscles of the heart cannot bear the exercises being carried out by the body.
- Other factors: Myocardial infarction causes are not only limited to the above. They could also be caused or induced by smoking, diabetes, nicotine intake, high cholesterol, high blood pressure among others; and these can cause myocardial infarction symptoms like difficulty in breathing among others.
- Acute chest pain: Symptoms like severe chest pains, occur first and are extremely painful. This could be angina or a plethora of other problems related to it.
- Un-healing wounds: Another symptom of an infarction is wounds that refuse to heal in a reasonable amount of time and pains in parts of the legs. Myocardial infarction causes blood not to flow to certain parts of the body affected by the arteries, and this could cause myocardial infarction symptoms like pain and weakness in the affected parts.
- Breathing difficulty: Infarction causes can lead to myocardial infarction symptoms like difficulty in breathing among others.
If you notice any chest pains, quickly consult your doctor for a proper diagnosis. It is always better to be safe than sorry.
