Q. What is myocardial infarction, and how does it occur?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Myocardial infarction, commonly known as a heart attack, is a serious medical condition that occurs when there's a sudden interruption of blood supply to a part of the heart muscle. This interruption usually happens because one of the coronary arteries, responsible for supplying blood to the heart, becomes blocked.
The main culprit behind this blockage is the accumulation of fatty deposits called plaque within the coronary arteries. When this plaque ruptures or a blood clot forms within it, it can obstruct the artery, cutting off the oxygen and nutrients that the heart muscle needs to function properly.
Here's how it happens step by step:
1. Plaque Buildup: Over time, factors such as high cholesterol, high blood pressure, smoking, and diabetes can lead to the buildup of plaque on the inner walls of the coronary arteries. This process is called atherosclerosis.
2. Plaque Rupture: Sometimes, the plaque can become unstable, leading to its rupture. This rupture can expose the inner core of the plaque, which contains substances that promote blood clot formation.
3. Blood Clot Formation: When the plaque ruptures, it triggers the body's clotting response. A blood clot, also known as a thrombus, starts forming at the site of the plaque rupture.
4. Artery Blockage: As the blood clot grows, it can completely block the coronary artery. This blockage prevents oxygen-rich blood from reaching the heart muscle downstream.
5. Heart Muscle Damage: Without oxygen, the heart muscle begins to suffer damage. The longer the blood supply is blocked, the more extensive the damage can be. This is why prompt medical intervention is critical during a heart attack.
The symptoms of myocardial infarction can vary from person to person but often include chest pain or discomfort, shortness of breath, nausea, lightheadedness, and pain radiating to the arm, jaw, or back.
Q. Hello Doctor, from past 3 weeks I have too much dandruff problem and it cause hair loss will you suggest any best solution for this?

Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
