Tobacco and Heart Disease: Tackling Bengal’s Smoking Culture

For many people, tobacco use—whether through smoking or chewing—may feel like a small habit or a coping mechanism in daily life. But behind that moment of relief lies a serious, ongoing threat to your heart.

Tobacco and heart disease are closely linked. Every puff of a cigarette or chew of tobacco introduces harmful chemicals into the body that directly damage the heart, blood vessels, and circulation. Over time, this silent damage increases your risk of a heart attack, stroke, or even sudden cardiac death.

Why is tobacco so harmful to your heart?

Tobacco smoke contains over 7,000 harmful chemicals, including three particularly dangerous ones:

• Nicotine: An addictive stimulant that increases blood pressure, tightens arteries, and makes your heart work harder.
• Carbon Monoxide: A toxic gas that reduces the oxygen your blood can carry, forcing your heart to pump faster and strain harder.
• Tar: A sticky substance that damages lung tissue, reduces oxygen flow, and contains dozens of cancer-causing chemicals.

Together, these substances directly increase your risk of heart disease, stroke, and peripheral artery disease—some of the leading causes of death worldwide.

How do smoking and chewing tobacco damage the heart?

Here’s what happens inside your body when you use tobacco:

1. Damaged Blood Vessels: Chemicals in tobacco injure the inner lining of your arteries, promoting plaque buildup (atherosclerosis), which narrows blood flow and increases the risk of heart attacks and strokes.
2. Increased Blood Pressure and Heart Rate: Nicotine causes your heart to beat faster and harder. Over time, this constant stress can lead to hypertension and weaken the heart muscle.
3. Lower Oxygen Supply:  Carbon monoxide from smoke replaces oxygen in your blood. This reduces the oxygen available to your heart, brain, and muscles, leading to fatigue and increased risk of cardiovascular events.
4. Higher Risk of Blood Clots:  Tobacco use makes your blood thicker and stickier, increasing the chance of clot formation. Clots can block blood flow to your heart or brain, causing life-threatening conditions like heart attacks or strokes.
5. Chewing Tobacco Is Not Safer :  Smokeless tobacco products such as gutka, khaini, and pan with zarda also raise blood pressure, damage blood vessels, and increase the risk of stroke and heart disease—contrary to common belief.

What are the common heart problems caused by tobacco use?

Tobacco use has been strongly linked to several major types of heart disease, including:

Smoking and heart disease

Early Symptoms of Heart Disease from Smoking

Heart disease often develops silently, but watch for these early warning signs—especially if you smoke or use tobacco:

• Shortness of breath, even with light activity
• Chest pain or pressure (angina)
• Fatigue or weakness without clear cause
• Irregular heartbeat or palpitations
• Swelling in legs or ankles
• Dizziness or fainting

If you notice any of these symptoms of heart disease, speak to your cardiologist promptly. Early diagnosis saves lives.

How does quitting tobacco improve heart health?

The good news? It’s never too late to quit. The benefits begin almost immediately:

These changes aren’t just numbers—they’re added years of better health, stronger heart function, and reduced medical complications.

How can you protect your heart if you’re a smoker?

If you use tobacco and want to protect your heart, here are a few simple steps:

1. Quit Tobacco: This is the most important step. Use quit programs, nicotine patches or gum, and talk to your doctor about support or medication.
2. Get Regular Checkups: Check your blood pressure, cholesterol, and blood sugar regularly to catch heart issues early.
3. Eat Heart-Healthy Foods: Choose fruits, vegetables, whole grains, nuts, and lean proteins. Cut back on salt, sugar, and processed foods.
4. Stay Active: Aim for 30 minutes of exercise most days—like walking, swimming, or cycling.
5. Manage Stress: Try deep breathing, meditation, or yoga to reduce stress and support heart health.
6. Drink Less Alcohol: Too much alcohol raises blood pressure. Drink in moderation or avoid it altogether.

Take the First Step Toward a Healthier Heart

If you use tobacco, the most powerful thing you can do to protect your heart is to quit. Quitting isn’t easy, but it is possible—with the right support.

Here’s how to start:

• Talk to your doctor or pharmacist about quitting tools like nicotine patches, gums, or prescription medications.
• Join a Quit Program—Support groups or behavioural counselling can increase your chances of success.
• Practice Healthy Habits—Exercise, eat a heart-healthy diet, and manage stress to support your heart as you quit.

Final Thoughts: Your Heart Deserves Better

Tobacco and heart disease go hand in hand—but you have the power to break the connection. Every cigarette skipped, every tobacco packet thrown away, and every quit attempt brings your heart closer to healing.

As doctors, we’ve seen firsthand the toll that smoking and chewing tobacco takes on the heart—and the incredible transformation that happens when patients quit. Whether you’re just thinking about stopping or ready to make the change, the most important thing is to begin.
