Understanding Heart Attacks and Heart Failure

Heart attacks and heart failure have become two of the most concerning health issues today. Over the past few years, hospitals across India have seen a significant rise in patients reporting chest discomfort, breathlessness, or fatigue — symptoms that may indicate serious heart problems. This alarming trend is largely attributed to rapidly changing lifestyles, increased stress levels, and poor dietary habits in both urban and rural populations. Experts warn that neglecting early signs and failing to manage underlying risks like hypertension and diabetes are driving this public health crisis. It underscores the urgent need for greater awareness and proactive health management.

Dr. Sohan, Consulting Physician at Secure Hospitals, Mysuru, shares valuable insights about the growing prevalence of heart attacks (myocardial infarction), early detection, and preventive steps everyone should follow to protect their heart health.

Why Are Heart Attacks Increasing?

According to Dr. Sohan, there’s been a noticeable increase in patients visiting hospitals for ECG (Electrocardiogram) tests and heart-related complaints, especially in the last few months. Many people, even without any significant symptoms, are getting themselves checked — which is both a good and bad sign. It shows increased awareness, but also rising anxiety about heart health.

Heart attacks, once considered a disease of older adults, are now affecting younger populations too. “About a decade ago, most cases were seen in people above 30 or 40,” explains Dr. Sohan. “Today, we frequently treat patients in their 30s.”

This trend reflects changing lifestyles — stress, poor diet, lack of exercise, and unhealthy habits are all contributing factors to cardiovascular disease.

Common Symptoms of a Heart Attack

Recognizing symptoms early can save lives. The common warning signs of a heart attack or heart failure include:

• Severe pain or discomfort in the chest, often felt as heavy pressure or a tight squeeze.
• Trouble breathing, particularly when moving or lying still
• Unexplained fatigue or weakness
• Excessive Sweating
• Nausea, stomach discomfort, or dizziness

Sometimes, the signs can be subtle. “A person may just feel unwell, complain of indigestion, or have mild pain”. “These can still be early indicators of a myocardial infarction.”

Noticing any of these symptoms? Seek immediate medical help immediately. Acting within the “golden hour” — the first hour after symptom onset — dramatically improves survival rates.

How to Know If You’re Having a Heart Attack?

People often confuse heart attack symptoms with acidity, muscle pain, or anxiety. The safest
approach is to get evaluated by a cardiologist or in the emergency department.

Doctors may perform quick tests such as:

• Echocardiogram – to assess heart function
• Blood tests – to look for cardiac enzymes that indicate muscle damage
• Angiogram – to check for blockages in the coronary arteries

Timely diagnosis and treatment can prevent complications and even heart failure. When in doubt, always seek immediate medical help; your life depends on it.

Preventing Heart Attacks and Heart Failure

Dr. Sohan emphasizes that prevention begins long before symptoms appear. “Everyone above 30 should get a yearly health check-up, whether they have symptoms or not,” he says. In countries like the U.S. and across Europe, this practice has been routine for decades — and India is gradually catching up.

Key Preventive Measures:

• Regular Health Check-ups: Early screening helps detect high blood pressure, diabetes, or cholesterol issues — all risk factors for heart disease.
• Adopt a Healthy Lifestyle: A balanced diet rich in vegetables, fruits, whole grains, and lean proteins is essential. Avoid junk food, fried items, and processed meats. Dr. Sohan also advises limiting non- vegetarian foods high in saturated fat.
• Quit Smoking and Limit Alcohol: Smoking (including beedis and cigars) damages blood vessels, while excessive alcohol can strain the heart and liver. Wearing a protective mask in a polluted environment helps cut down on your body’s intake of harmful substances.
• Exercise Regularly: Being physically active makes your heart stronger and boosts blood flow. “Aim for at least 30–40 minutes of exercise, five days a week,” Walking, swimming, or cycling are excellent options.
• Get Enough Sleep and Manage Stress: Poor sleep and high stress are silent contributors to heart failure. Practicing relaxation techniques like yoga, meditation, or deep breathing can make a big difference.

Addressing the Myths: COVID Vaccines and Heart Issues

One of the most widely circulated misconceptions in recent years is that COVID-19 vaccines cause heart attacks. Dr. Sohan clarifies:

“While it’s true that more cases appeared after the pandemic, there is no scientific evidence linking vaccines like Covishield, Covaxin, or Sputnik to heart failure or heart attacks.”

Instead, it can be the virus itself that can cause long-term inflammation or alter heart receptors, leading to complications.

Dr. Sohan adds, “Please don’t rely on rumors — always consult a qualified physician or cardiologist before believing such claims.”

What to Do During a Suspected Heart Attack?

• Act Fast: Reach a hospital immediately — ideally within the first hour. This window offers the best chance to restore blood flow and minimize permanent heart damage. If an ambulance is not immediately available, have a friend or family member drive. Do not drive yourself!
• Don’t Travel Far: Go to the nearest primary care center or emergency room first. They can administer initial life-saving medications and injections to stabilize the patient before a transfer to a specialized cardiac unit is attempted.
• Stay Calm: Sit upright, avoid exertion, and call for help. Remaining calm and still helps reduce the heart’s workload and limits its demand for oxygen.
• Follow Medical Advice: Once at the hospital, doctors will diagnose the issue and may perform angioplasty (inserting a balloon and stent to open a blocked artery) or administer clot-busting drugs. Cooperate fully and provide a list of current medications and allergies to streamline this critical process.

With prompt care, 70–80% of heart attack patients can be saved.

Managing Chronic Conditions

People with hypertension, diabetes, kidney disease, or prior heart conditions should visit their doctor at least once every three months. These conditions often go hand-in-hand with heart failure.

“People frequently travel to new places and eagerly try different foods, but they avoid visiting their doctor — that’s not right,” says Dr. Sohan. Regular monitoring helps manage risk and prevent complications.

How to Avoid Heart Failure?

When the heart can’t circulate blood efficiently throughout the body, it results in heart failure. Preventing it involves:

• Keeping blood pressure and blood sugar under control
• Maintaining a healthy weight
• Taking medications as prescribed by your doctor
• Limiting salt intake
• Staying physically active
• Avoiding smoking and alcohol

Early detection is key. If you experience persistent fatigue, swelling in the legs, or breathlessness, get an echocardiogram to assess your heart’s pumping capacity.

The Takeaway: Health Is Wealth

As Dr. Sohan reminds us, “Health is very precious. Don’t neglect it.” See his full video explanation here

The message is simple — awareness, timely action, and lifestyle changes can prevent most heart-related emergencies.

“Take care of your life and help others take care of theirs,” he says.

“Get regular check-ups, stay active, and don’t ignore warning signs. The heart deserves your care.”

Is Walking a Full-Body Workout for Weight Loss?

Walking is one of the easiest, most convenient, and often overlooked forms of exercise. It doesn’t require a gym membership, expensive equipment, or special training. Yet, it can play a major role in maintaining fitness, improving cardiovascular health, and aiding weight management. But is walking truly a full-body workout for weight loss? Let’s explore how walking contributes to fitness, the best times to walk, and its impact on cholesterol and overall well- being.

Walking and Weight Loss: How Effective Is It?

You might be able to lose weight by walking, but the results depend on intensity, consistency, and diet. Walking is a low-impact aerobic activity that primarily engages your lower body muscles—legs, hips, and glutes—while also activating your core and arms, especially during brisk walking.

For weight loss, the key is to burn more calories than you consume. While walking alone can help, combining it with a balanced diet and other physical activities can significantly improve results. Studies suggest that 30 minutes of brisk walking can burn approximately 150 extra calories. The faster and longer you walk, the greater the calorie burn.

If you can’t manage 30 minutes in one go, don’t worry. Short, frequent walks throughout the day—such as a 10-minute stroll after each meal—can still add up and offer meaningful benefits. Walking doesn’t just support weight management; it also boosts mood, relieves stress, and supports long-term heart health.

Making Walking Enjoyable and Sustainable

One of the reasons people often give up on exercise routines is lack of enjoyment. Walking, however, can easily become an enjoyable and social activity. Walking with friends, family, or colleagues not only keeps you motivated but also turns your workout into a meaningful social engagement. You can chat, share updates, or even listen to music or podcasts while walking.

Moreover, walking exercise for beginners is ideal because it’s suitable for nearly everyone— overweight individuals, beginners, and older adults—since it’s gentle on the joints and carries a lower risk of injury compared to high-impact workouts like running or jumping. It’s an excellent way to stay active, especially for those who have mobility limitations or are new to fitness.

Another advantage is that walking requires minimal equipment. A comfortable pair of shoes and suitable clothing are often all you need. This makes it one of the most accessible and sustainable forms of physical activity for daily life.

How Much Should You Walk per Day?

If your goal is weight loss, the duration and intensity of your walks matter. To achieve your physical fitness goals, knowing the walking health benefits is key to staying consistent with your daily routine. For weight reduction, experts recommend extending your walking time beyond 30 minutes daily. You can gradually increase your duration as your fitness improves.

Consistency is the secret. Even if you can’t dedicate a full 30-minute block, breaking your walks into shorter sessions—for example, three 10-minute walks spread throughout the day—still provides meaningful results.

Additionally, incorporating more walking into your daily routine helps increase overall physical activity without extra effort. Some simple ways include:

• Using stairs instead of elevators whenever possible.
• Walking part of the way home from the office instead of driving the entire route.
• Choosing to walk to nearby stores or markets instead of using a two-wheeler or car.
• Scheduling short walking breaks during work hours or after meals.

These small adjustments contribute to a more active lifestyle and help maintain a steady calorie burn throughout the day.

Recommended Walking Duration by Age

18-30 years: 30-60 minutes/day – Young adults should aim for brisk walking to manage weight, reduce stress, and support heart health. Desk workers should take regular walking breaks.

31-50 years: 30-45 minutes/day – Adults benefit from walking to maintain muscle tone, control weight, and prevent chronic illnesses. Incorporate walking into commuting, lunch breaks, or stair use.

51-65 years: 30-40 minutes/day – Middle-aged individuals should walk to support bones, joints, and metabolism. Using poles, slight inclines, and warm-up/cool-down routines improves safety and results.

66-75 years: 20-30 minutes/day – Moderate walking helps older adults stay active, maintain balance, and boost mood and cognition. Splitting sessions or walking in groups adds motivation.

Seniors: 15-20 minutes/day – Short daily walks maintain joint flexibility, muscle strength, and balance while keeping activity safe.

Best Time to Walk

Many people wonder whether the timing of a walk affects calorie burn or fat loss. In reality, the number of calories burned depends on your pace, duration, and body weight, not on the time of day. However, choosing a time that fits your lifestyle and allows consistency is most important.

A study suggests that exercising between 7 a.m. and 9 a.m. may be more effective for weight management and regulating your body’s internal clock. Morning walks can also energize you for the day, improve mental clarity, and enhance focus.

However, not everyone is an early riser. For those who find morning routines difficult, evening walks can be a great alternative. Evening strolls help relieve stress after a long day, improve digestion, and prepare your body for better sleep.

Ultimately, the best time to walk is the time that you can stick to consistently—whether that’s early morning, during lunch breaks, or after dinner. The real benefit comes from regularity, not timing.

Can Walking Lower Cholesterol?

Walking doesn’t just help with weight control—it also supports heart health and cholesterol balance. Regular walking can increase levels of HDL cholesterol (the “good” cholesterol), while lowering LDL cholesterol (the “bad” cholesterol) and total cholesterol levels.

According to research published in the British Journal of Sports Medicine:

• Walking the same distance faster improves HDL-C (good cholesterol) more effectively.
• Walking at a slower pace leads to a greater decrease in LDL-C and total cholesterol, independent of body weight changes.

This means both brisk and moderate-paced walking have unique cardiovascular benefits. Regular walking, even without significant weight loss, helps keep cholesterol levels in check and supports long-term heart health.

Combining walking with a balanced diet rich in fruits, vegetables, whole grains, and healthy fats further enhances these benefits. It’s an easy, medication-free way to manage cholesterol naturally and protect your heart.

Why Walking Deserves a Place in Your Routine

Walking might seem simple, but its cumulative effects on physical and mental health are profound. It not only aids weight management but also reduces the risk of chronic diseases like diabetes, high blood pressure, and heart disease. It helps improve sleep quality, reduce stress, and elevate mood through the release of endorphins.

Most importantly, walking is sustainable for life. You can start small, progress gradually, and continue enjoying its benefits at any age or fitness level.

Important Takeaways:

• Start with short, manageable sessions and increase your duration as you build stamina.
• Stay consistent—daily movement matters more than intensity alone.
• Mix walking with other activities like light stretching, yoga, or cycling for overall fitness.
• Keep it enjoyable—walk with others, explore new routes, or listen to music.
• Focus on lifestyle integration rather than treating walking as a temporary fitness plan.

Final Thoughts

So, is walking a full-body workout for weight loss? While it may not engage every muscle group like strength training, it’s a highly effective, low-impact exercise that supports full-body health, calorie burning, and fat reduction—especially when paired with a healthy diet.

Whether you walk in the fresh morning air or unwind with an evening stroll, remember that every step counts. Over time, these steps contribute to improved fitness, better mood, balanced cholesterol levels, and sustainable weight management.

Make walking a part of your daily routine—and walk your way to better health.
