Frequently Asked Questions

Based on the variation in the ECG during a heart attack, doctors recognize two types of heart attacks. ST-elevation Myocardial Infarction (STEMI) Non-ST-elevation Myocardial infarction (NSTEMI). STEMI and NSTEMI differ not only in the variation in the ECG but also in their severity. In general, STEMI is more likely to be immediately fatal or disabling than NSTEMI. Consequently, STEMI requires more urgent treatment than NSTEMI in most instances. However, this is just a thumb rule: Some NSTEMIs can be equally ominous and may require emergency treatment just like STEMI.

First, seek help. Make any person in proximity aware of your situation. The most important step to ensure a safe outcome in a heart attack is to see that you reach a hospital with appropriate facilities as soon as possible. It is a good practice to be aware of the hospitals around you and the facilities they provide. When someone has chest pain or other symptoms suggestive of a heart attack, the immediate first aid should be to take 350 mg of the soluble form of Aspirin (common trade names Disprin or Aspisol in India). Ideally, the tablet should be chewed because the medicine is absorbed from the mucosal membrane of the oral cavity and starts to act immediately. If the patient cannot chew the tablet for some reason, the tablet can be dispersed in a small quantity of water and taken orally. If I see someone who is having a heart attack, what can I do to ensure he survives till help arrives? Call the nearest hospital with cardiac facilities as soon as you recognise that someone around you might be having an ongoing attack. Shift the person to a comfortable position and reassure them. If possible, give them an Aspirin tablet to chew. While waiting for help to arrive, monitor their breathing and pulse. If they lose consciousness, initiate Cardiopulmonary resuscitation (CPR).

Various risk factors increase the chances of a person having a heart attack. Smoking, High Blood pressure, Diabetes. physical inactivity, high cholesterol levels, obesity, and poor diet are important risk factors. These can be potentially controlled to reduce heart attack risk. Therefore, these are termed Modifiable Risk factors. Older age, male sex, family history, Post-menopausal state in women are factors that can increase heart attack risk but cannot be altered. These are called non-modifiable risk factors. South Asians appear to have a very high risk of having heart attacks at a younger age, compared to Caucasians and Asians such as Japanese.

It is a procedure to detect blockages in the blood vessels of the heart. A thin hollow tube or catheter is inserted via the artery of the forearm or the thigh. Through this catheter, a special contrast dye is injected into the coronary arteries and X-ray images are obtained to visualize the blood flow in the coronary arteries.

Coronary angioplasty is a procedure performed to widen narrow or blocked sections of the coronary vessels thereby restoring the blood flow. A thin balloon is inserted into the coronary artery and inflated at the site of the block to widen the narrowed artery. This makes a way for the opening of the blockages. A stent is generally then placed to prevent future blockages.

Coronary Artery Bypass Grafting (CABG) is a procedure where a surgeon makes new routes (bypass) around blocked or narrowed coronary arteries with one or more grafts allowing increased blood flow to the vessel past the blockage. These grafts are typically healthy blood vessels from the chest, arm, or leg of the patient.

There are various types of disorders related to the heart. Congenital heart disease is a defect of the heart which are present since birth. Arrhythmias are abnormal heart rhythm or irregular heartbeat affecting the electrical conduction. Coronary artery disease is caused by the narrowing of the coronary arteries leading to the decreased blood supply to the heart. This can potentially lead to angina, heart attacks, weakening of the heart muscle, or sudden death. Cardiomyopathy refers to diseases affecting the heart muscle. Some types of cardiomyopathy are genetic, while others occur because of an infection or reasons that are less well understood. Heart failure happens when the heart is not properly pumping blood throughout the body. In this condition often the heart's pumping capacity is reduced. Valvular heart disease affects how the valves function to regulate blood flow in and out of the heart chambers. Hypertension is a condition in which the blood vessels have persistently increased pressure, putting them under increased stress. It is often known as high or raised blood pressure. Pericardial diseases affect the outer layer (pericardium) of the heart. It can be affected by a variety of conditions that include inflammation (pericarditis), stiffness (constrictive pericarditis), and fluid accumulation (pericardial effusion).

In some patients, the blood supply to a part of the heart muscle stops suddenly. This happens most often due to the formation of a clot inside one of the three coronary arteries supplying blood to the heart muscle. When this happens, the heart muscle that receives blood from the respective coronary artery gets damaged. This is termed as a heart attack. It is advised to quickly visit the Best Cardiology Hospital in Bangalore nearby to get treated by a cardiologist.

Family history plays an important role in the causation of heart attacks. The risk of a heart attack in a person more than doubles if a first-degree relative (parents, siblings, or children) has had a heart attack in the past. While there are exceptions, heart attacks are generally seen in older adults. The typical age for a man to have a heart attack is 55 years and above and for a woman it is 65 years and above. When heart attacks are seen in men younger than 55 years and women younger than 65 years it is termed as Premature Heart Attack or Premature Coronary artery disease. In India, during the last two decades, more and more adults who are younger have been noted to have heart attacks. Studies have shown that between 15-22% of all heart attacks are seen in adults younger than 40 years of age.

Of course not. Symptoms of heart attack can vary from case to case. The commonest symptom of a heart attack is chest pain. This is seen in about 70% of all heart attack patients. The remainder can present with breathlessness, arm or back pain, cold sweats, loss of consciousness, or palpitations. Some patients may have no symptoms at all and are said to have a Silent Heart attack. If you experience any of these symptoms, then immediately consult the Best Cardiologist in Bangalore.
