A myocardial infarction is a heart attack. This is when the flow of blood to the heart is essentially blocked.
Cause of disorder
The cause of a heart attack is a build up of fat, cholesterol, or other substances in the body to create a plaque. This plaque blocks the left anterior descending coronary artery that leads to the heart, thus preventing the flow of blood to the heart. When the heart does not receive enough blood damaging/destroying the muscles in the heart that make it pump.
The symptoms of this disorder vary from person to person and could range from mild symptoms to extremely severe. Fatigue. Cold sweats. Light-headedness or dizziness. Tightness, pressure, pain, aching, or squeezing in various areas of the body. Nausea, heartburn, indigestion, or abdominal pain. Shortness of breath.
There are several diagnostic tests that can be performed to diagnose this disorder.
-Electrocardiography (ECG): this test shows that a heart attack may be in progress or that one has already happened. This records the electrical activity of your heart via electrodes. An injured heart won't conduct the electrical impulses accurately.
-Blood Tests: there are certain heart enzymes that leak into the blood if you heart has been damaged by a heart attack.
-Chest X-Ray: this allows a doctor to view your heart and its arteries and the lungs to look for fluid.
-Exercise Stress Test: this is conducted days/weeks after a heart attack. This measures how your heart and blood vessels respond to exertion.
-Other tests include: Echocardiogram, Coronary Catheterization, CT, and MRI.
Men: 600 per 100,000
Women: 200 per 100,00
-Medications: help to reduce another heart attack and help a heart to function better.
-Lifestyle Factors: maintaining a healthy weight, eating healthy, managing stress, exercising, and maintaining health conditions that could lead to a heart attack.
-Age -Lack of Physical Activity -Tobacco Use
-History of Preeclampsia Stress
-High Blood Pressure -Illegal Drug Use -High Cholesterol
-Diabetes -Family History of Heart Attack -Obesity
-History of an Autoimmune Condition
-Medications: Aspirin, Thrombolytics, Antiplatelet Agents, Blood-Thinning Medications, Pain Relievers, Nitroglycerin, Beta Blockers, and ACE Inhibitors.
-Coronary Angioplasty and Stenting: this is the insertion of a catheter that's passed through an artery (in your leg or groin) to the blocked artery in your heart. This locates and opens blockages with the use of a balloon. And a metal mesh stent is used to open the artery long term.
-Coronary Artery Bypass Surgery: this involves sewing veins or arteries in place beyond a blocked/narrowed coronary artery, allowing blood flow to the heart.
