Myocardial infarction (MI), is the technical term for heart attack. It is a result of temporary or reduced supply of blood to the heart muscle causing cell damage from lack of oxygen. This is due to the blockage of coronary artery.
About 1/5 of myocardial infarctions are silent that patients are unaware that MI has already occurred. Although they feel no pain, silent MI can still damage the heart. Typically, patients with myocardial infarction will feel sudden chest pain radiating to the left arm and neck or chest discomfort accompanied by shortness of breath, lightheadedness, nausea, sweating, and fainting. Not everyone has the same symptoms, but 60% of patients experience symptoms days or weeks prior to myocardial infarction. Some symptoms may even disappear and reappear.
Myocardial infarction occurrence
Approximately, 1.5 million cases of myocardial infarction occur in the United States every year, and almost 500,000 die American Heart Association. It is the leading cause of emergency medical treatment and death among men and women age 35 to 65. However, a number of research found that older women will likely die of MI than men. While studies in Europe and the UK have focused on women, protection little has been done to delineate why women have increased risk once myocardial infarction is manifest.
Some of the risk factors are male or female who have gone through menopause, family with history of heart attack, smoking, excessive alcohol consumption, high cholesterol and triglycerides, high-fat diet, diabetes mellitus, elevated blood pressure, cardiovascular disease, obesity, kidney disease, stress. Age incidence varies between countries.
Myocardial infarction aftermath is always severe and 2/3 of patients never recover fully. Approximately, half of the patients with MI died within one year, but fatalities differ between populations. Within a year, 44% of women and 27% of men die and within six years, 31% of women and 23% of men will have another myocardial infarction. People who survive a MI have four to six times higher chance of sudden death greater than others.
Lifestyle change can reduce your risk of developing coronary heart disease that can cause MI. If you’ve had a myocardial infarction, follow your doctor’s order to prevent another attack.
Keep a healthy lifestyle that includes regular aerobic exercise, eating low-fat diet, moderate drinking, no smoking or illegal drugs and stress management to maintain your blood pressure.
Clinical Study for Predicting Near-Term Myocardial Infarction
A clinical study on non-invasive health and diagnostic tests to predict the near-term myocardial infarction will be published online this week and in the July 23, 2013 printed edition of the Journal of the American College of Cardiology.
The clinical study demonstrated the effectiveness of the test in identifying both the low and high-risk patients so that cardiologists can devise rational strategies for individualized therapy and diagnostic testing.
