Dr Jeremy London outlines crucial steps to take if alone during a heart attack, highlighting that awareness and preparedness are vital in emergencies.

Heart attacks are one of the leading causes of death globally and in India, representing about 20 percent of global heart attack deaths. According to the World Heart Federation, India had 3,165,172 deaths from cardiovascular disease (CVD) in 2024.

What to do if you are home alone and have a heart attack?

Therefore, if you have a history of heart disease, it is important to educate yourself and prepare your family members in case of an emergency. But what happens if you have a heart attack when you are home alone?

1. Call 911

The foremost thing, according to Dr London, is to call 911 or any emergency service number in your country. Dial 112 or 108 immediately in India for a medical emergency, such as a heart attack.

2. Unlock or open your door

The next thing, Dr Jeremy stressed that if it is nighttime, it is important that you turn on the lights on your porch or outside your house so that emergency medical services can identify your house. He also advised opening or at least unlocking the front door so emergency medical services can access your house. “Because if you are incapacitated, they have no way to get in,” he underlined.

3. Sit down or lie down

Next, once the doors are unlocked, Dr Jeremy advised patients to lie down or sit on the couch, whichever's comfortable, wherever they're breathing easiest. “Lying down and elevating your feet typically gives people the most relief, but put yourself in a stationary position so if you do pass out, you don't fall and add a head injury to an already bad situation,” he explained.

4. Notify a friend or family member

He also recommended calling family or friends to let them know what's happening, so someone knows emergency medical services are coming and that you're going to the hospital.

Lastly, in addition to calling emergency services, ensuring your home is visible, resting comfortably, and alerting family or friends, Dr Jeremy also advised chewing a single non–enteric-coated aspirin (162–325 mg) while waiting for help. He stated that unless there is a known aspirin allergy, active bleeding, or a clinician has told the patient not to take it, one can safely consume the medicine.
