What is Myocardial Infarction (MI) / Unstable Angina?
These are often grouped together under the term "Acute Coronary Syndrome" (ACS) and are potentially life-threatening. This occurs when a blood vessel supplying the heart is blocked, usually by a blood clot. Risk factors include high cholesterol, high blood pressure, a sedentary lifestyle, diabetes, and a family history of cardiovascular diseases (e.g., stroke, heart disease).
Typical Symptoms of Myocardial Infarction (MI) / Unstable Angina
- Stomach or abdominal pain in a specific area
- Bluish or pale skin
- Breathing is harder when lying down, improves when sitting up
- Left-sided chest pain
- Kidney failure on dialysis
- Losing consciousness during a physical activity
- Jaw pain
- Cold hands and feet
Diagnostic Questions for Myocardial Infarction (MI) / Unstable Angina
Your doctor may ask these questions to check for this disease:
- Do you have stomach or abdominal pain in a specific area?
- Do you have any bluish or pale skin?
- Does your breathing improve when you sit up from lying down?
- Do you have pain on the left side of your chest?
- Are you currently on dialysis?
Treatment of Myocardial Infarction (MI) / Unstable Angina
This is a medical emergency and requires prompt medical attention in the hospital. Treatment aims to restore blood supply to the heart with medication to reduce blood clot size, prevent clot formation, and reduce the workload of the heart. Surgery or procedures are performed to open up the blocked artery supplying the heart or reroute blood around the blocked area.
