What Exactly Happens in a Heart Attack?
Your heart is like the engine of your body and is always working to keep things running smoothly. A heart attack occurs when the blood flow that keeps the heart’s rhythm going gets blocked, usually by fatty build-up (plaque) in the arteries. Without oxygen, part of the heart muscle starts to suffocate.
Every year, over 17 million people die from heart-related diseases, and heart attacks are a major cause. In India, someone has a heart attack roughly every 33 seconds.
It is also helpful to understand the distinction between a heart attack and a stroke. And just to clear up confusion:
- Heart attack = blockage in the blood flow to the heart.
- Stroke = blockage (or bleed) in the blood flow to the brain.
Practical Steps to Prepare for a Heart Attack
Knowledge is power and especially when it comes to your health. By understanding the risks, recognising the warning signs, and focusing on prevention, you give yourself the best chance of protecting your heart health.
Understand the Risks
You might think you’re clear because you hit the gym and generally eat well, but some risk factors are out of your control. Heart problems don’t pop up overnight like a surprise test. They build over time. Some things raise your odds:
- Family history & genetics: If your parents or grandparents had heart disease, you’ve got to be extra alert.
- Age: Risk increases after 45 for men and 55 for women.
- High cholesterol, diabetes & high blood pressure: These conditions quietly damage arteries over time.
- Inflammation & oxidative stress: Fancy words for the body dealing with stress, smoking, junk food, or pollution, all of which crank up risk.
Know the Signs of a Heart Attack
Contrary to movie scenes, heart attacks aren’t always dramatic. Symptoms can be subtle and easily mistaken with indigestion or fatigue, and even vary between men and women.:
- Chest discomfort or pressure (often described as “an elephant sitting on your chest”)
- Pain spreading to arms, jaw, neck, or back
- Trouble breathing
- Cold sweat, nausea, or dizziness
Mini-narrative: Imagine you are scrolling Instagram at midnight when suddenly your chest feels heavy like someone dropped a dumbbell on it. That’s not “just stress,” but it’s a signal you should never ignore.
Focus on Prevention
Preparation isn’t just knowing CPR or emergency numbers. Everyday habits, from the food on your plate to the way you handle stress, can create the foundation for long-term heart health.
Tips to Boost Your Heart Health
Now that we’ve covered the risks and signs, let’s talk about what you can do daily to keep your heart in top shape. These lifestyle tweaks aren’t just good for your heart, but they’ll boost your energy, sleep, and overall confidence in your health.
Avoid Smoking
Smoking is like giving your heart a one-way ticket to trouble. It damages the lining of your arteries and makes your blood stickier, making it easier for clots to form. But the good news?
Quitting cigarettes is like deleting malware from your system. Within a year of quitting, your risk of heart disease can drop by 50% and your heart will literally thank you.
Engage in Physical Activity
No need to go from zero to marathon runner. Just moving your body is the goal. Activities like brisk walking, cycling, swimming, or even dancing can get your heart pumping. When you exercise, you train your heart to work more efficiently, like a well-oiled machine. It also helps manage weight, lower blood pressure, and reduce stress.
Mini-narrative: You’ve been sitting on Zoom calls all day. Stand up, put on your favourite track, and dance like no one’s watching (except maybe your cat). Your heart will love it.
Eat a Healthy Diet
You’ve heard it before, but what does it really mean? Food is fuel, not filler. Shifting focus to nutrition, foods like avocados, berries, leafy greens, and whole grains deliver protection against cholesterol buildup. These choices, more than restrictive dieting, nurture heart health with lasting effects.
Maintain a Healthy Weight
Weight matters, but it’s not just about the number on the scale. Body Mass Index or BMI is a useful guide to aim for a range between 18.5 and 24.9. But also pay attention to belly fat (visceral fat), which can increase heart disease risk even if your BMI is normal.
Quick tip: Your waist should be less than half your height. So if you’re 170 cm tall, aim for a waist under 85 cm.
Get Adequate Sleep
Sleep isn’t a luxury; it’s a necessity, and your heart needs downtime, too. Getting less than six hours a night is like running your body on low battery mode. It raises blood pressure and stress hormones, leaving your heart overworked and irritable.
Manage Stress
Besides sleep, managing stress has a scientifically proven impact on heart health. And let’s be honest, everyone’s life is filled with stress these days, whether it is a bad date, a tough day at work, or even traffic that refuses to move. But chronic stress can be dangerous and, quite literally, life-threatening.
Some simple ways to manage it include:
- Using mindfulness apps (even a 5-minute guided breathing session can help)
- Practising yoga or stretching after work
- Switching from doomscrolling to reading or music
- Trying meditation or focused breathing exercises
- Journaling as a way to release thoughts
- Laughing at memes (yes, laughter really does lower stress hormones)
Get Regular Health Screenings
Routine check-ups aren’t just boring; they are a way to keep track of your overall health. Connect to your doctor about how often you should check your blood pressure, cholesterol, blood sugar, and kidney health, especially if heart disease runs in the family.
- Cholesterol: Every 4 to 6 years, or more often if you are at risk.
- Blood sugar (A1C): Especially important if diabetes runs in the family.
- Kidney function: High bp and diabetes can affect kidney health, which in turn impacts your heart.
Conclusion: Heart Healthy Lifestyle is Key to Prevention
Preventing heart attacks isn’t about living in fear but about making smart choices. Simple steps like staying active, eating well, getting enough sleep, and managing stress can lower your risk. These habits give you more energy, confidence at checkups, and peace of mind that your heart is in good shape.
