A heart attack is a type of Cardiovascular disease (CVD), which is one of the leading causes of death in many countries across the globe.

According to the World Health Oraganization (WHO), "an estimated 17.9 million people died from CVDs in 2016, representing 31% of all global deaths. Of these deaths, 85% were due to heart attack and stroke."

Reporting on the same topic in India, WHOglobal health data states, "In 2016, India reported 63% of total deaths due to NCDs, of which 27% were attributed to CVDs. CVDs also account for 45% of deaths in the 40-69 year age group."

Now that we know the facts and data, it is crucial to take proactive steps to educate ourselves about heart disease prevention and adopt a lifestyle to promote a healthy and long life.

Offering valuable guidance on this front, Madhuri Dixit's husband, Dr. Shriram Nene, who is a cardiologist, shares practical tips and tricks to tackle a heart attack during Ranveer Allahbadia's podcast, The Ranveer Show.

In a recent Instagram post, Allahbadia, who shared a snippet of the podcast, wrote, "Dr. Nene explains the 3 major artery blockages that lead to a heart attack: Understanding the causes behind heart attacks is crucial for prevention."

He continued in the video, asking Dr. Nene, "When someone gets a heart attack, effectively what happens?"

The cardiologist answers, "What happens is that there may be a blockage in one of the 3 main arteries or in the left main artery, which doesn't allow blood to flow to the part of the muscle and all the tissues involved. When that happens, that muscle or that area, basically, will stop working. That's when you have the chest pain radiating to your arm, the shortness of breath, the sweaty nose, the palpitations."

Dr. Nene added that, "Surprisingly, 20% of patients never have symptoms. And in the case where people have no symptoms at all, they collapse. They can have a cardiac arrest, or they can faint, or they can just not feel good. So, you have no blood flow to the brain, right? So, you have a syncopal episode, or your heart is not pumping at all with a very fast heart rhythm. And none of that blood is going to the rest of the body,"
