Angina and a heart attack, also known as myocardial infarction, are both heart-related cardiovascular illnesses, but they differ greatly in terms of their underlying causes, signs, and symptoms, and severity.
Angina, sometimes referred to as angina pectoris, is a sort of discomfort or pain in the chest that develops when the heart muscle isn’t supplied with enough oxygen-rich blood. It frequently indicates a heart issue that is underlying, most frequently coronary artery disease (CAD).
CAD happens when plaque (a buildup of cholesterol, fat, and other chemicals) on the walls of the arteries supplying blood to the heart narrows or blocks them. When the heart’s need for oxygen-rich blood increases, as it does during physical activity or mental stress, this narrowing or obstruction may restrict blood flow to the heart.
Lack of oxygen caused by decreased blood flow to the heart muscle results in pain or discomfort in the chest region. Symptoms of angina include tightness, pressure, burning, or squeezing in the chest. The neck, jaw, shoulder, or back may also be affected, frequently the left arm. Angina attacks can range in severity and duration, and rest or nitroglycerin medication frequently helps to reduce the symptoms.
A heart attack, sometimes referred to as a myocardial infarction, is a medical emergency that happens when blood supply to a section of the heart muscle suddenly stops. This obstruction is typically brought on by a blood clot that develops in a coronary artery, which supplies the heart with oxygen-rich blood. Without adequate blood flow, the affected area of the heart muscle may start to deteriorate due to a lack of nutrients and oxygen.
The most common reason for a heart attack is atherosclerosis, which is the buildup of fatty deposits (plaque) on the walls of coronary arteries. Blood clot formation brought on by plaque rupture may result in obstruction.

Frequently Asked Questions (FAQS)
Q1. What brings on angina?
Coronary artery disease (CAD), in which plaque accumulation narrows the arteries and lowers blood flow to the heart, is the main cause of angina.
Q2. What is the sensation of angina?
Pressure, squeezing, burning, or tightness in the chest are common angina symptoms. The arms, neck, jaw, shoulder, or back may all experience radiating discomfort.
Q3. What is the sensation of angina?
Physical strain, emotional stress, exposure to chilly conditions, or hefty meals can all cause angina.
Q.4 Is angina a serious medical problem?
When angina is not a medical emergency in and of itself, severe or increasing angina, especially if it happens when you are at rest, could be a warning of unstable angina or a coming heart attack and has to be treated right once.
Q.5 What distinguishes stable from unstable angina?
Rest or medicine can treat stable angina, which happens predictably after physical activity. Unstable angina is more worse, can happen when you’re at rest, and frequently signals a coming heart attack.
Q.6 Do women have unique heart attack symptoms?
Yes, women can have distinct heart attack symptoms than males, and these symptoms frequently include back pain, nausea, and shortness of breath in addition to chest discomfort.
Q.7 When should I visit a doctor if I have chest pain?
Seek emergency medical assistance if your chest discomfort is severe, lasts for more than a few minutes, or is accompanied by other symptoms including shortness of breath, nausea, or cold chills.
