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.

Q.
Scared of Blockage? Why Your Heart Needs Angioplasty and Medically Approved Next Steps
A.
Angioplasty is a minimally invasive way to open blocked coronary arteries, restore blood flow, ease chest pain, and during a heart attack save heart muscle and lives, with serious complications uncommon in experienced hands; it treats the narrowed artery but not the underlying coronary disease. The medically approved next steps include urgent care for warning symptoms, prompt doctor evaluation and testing, an individualized decision between angioplasty and medications, and strict adherence to antiplatelet therapy plus lifestyle risk reduction; there are several factors to consider, so see the complete details below to understand timing, safety, and alternatives that could change your plan.

Q.
Nitro Not Working? Why Your Chest is Still Tight & Medical Next Steps
A.
If nitro does not ease chest tightness within minutes, it could mean the pain is not angina, a heart attack or unstable angina is developing, you have nitrate tolerance, or the dose, timing, or storage was off. Use the 5-minute rule up to 3 doses and call emergency services if pain persists or red flag symptoms appear; do not drive. There are several factors to consider, and important details about other causes, risk factors, and what doctors will do next are explained below.
