The main cause of death globally is still heart disease. Heart attacks may occur suddenly without any warning signs. However, in the film industry, intense chest pain would be portrayed for a heart attack. In actuality, many patients have slight symptoms that go unnoticed until the time of their heart attack days or even weeks prior to that.

Heart attacks do not always announce themselves with dramatic chest pain. Often, they manifest in subtle, easy-to-dismiss ways. Recognizing these overlooked warning signs and taking proactive steps toward cardiovascular health can save lives. If you or someone you know experiences any of these symptoms, seeking immediate medical care is crucial. Prioritizing heart health today can help prevent life-threatening complications in the future.

Warning Sings of A Heart Attack

1. Discomfort Pressure in the Chest

One of the earliest and most common warning signs of an impending heart attack is pressure, tightness, or fullness in the chest. This pain is not typically sharp and sudden, like most people associate with a heart attack, but it can be intermittent, coming in waves, and lasting for several minutes before fading away. According to the American Heart Association, this is one of the red flags when accompanied by exertion. If you have persistent chest pressure, you should call emergency services immediately.

2. Pain Radiating to Other Parts of the Body

The well-known symptom of chest pain can also manifest discomfort related to a heart attack as pain radiating to other parts of the body. It is not unusual for people experiencing this kind of heart attack to report feeling pain in the shoulders, arms, back, neck, and even jaw. The vagus nerve is one that connects the heart to the brain, abdomen, and neck. The pain may be referred to these regions. In case you experience a sudden, unexplained pain in these regions, especially when exercising, seek a doctor's opinion.

3. Dizziness and Lightheadedness

Feeling dizziness upon standing up quickly or missing a meal is common, but unexplained dizziness often with chest pain or shortness of breath is the first sign of heart attack. Sudden hypotension can seriously decrease the blood supply to the brain and cause dizziness. Dizziness that does not go away on its own should not be ignored.

4. Unexplained Fatigue

It often happens that excessive tiredness, particularly in a busy lifestyle, is considered trivial, but ongoing fatigue, mostly in women, is a predictor of heart failure. According to some studies, extreme fatigue often starts a month before a heart attack, primarily in women. This is simply because the heart cannot pump well enough, leaving insufficient oxygen available to muscles and organs. Consult a healthcare professional if you become increasingly tired over time, yet are getting all the rest in the world.

5. Nausea, Indigestion, or Stomach Pain

Digestive problems like nausea, vomiting, or indigestion are often mistaken for acid reflux or food poisoning. However, these symptoms can also indicate reduced blood flow to the digestive tract, a common precursor to heart attacks. If you experience gastrointestinal distress alongside other symptoms like dizziness or chest discomfort, it's important to seek medical advice immediately.

6. Cold Sweats and Excessive Perspiration

Without apparent reason, a heart attack might be signaled by sudden sweating without any exercise or hot weather conditions. The heart's inability to function properly creates the body's "fight or flight" reaction, which means excessive sweating will occur. Be aware of your body and never ignore a cold sweat, particularly if it coincides with other symptoms.

7. Heart palpitations or irregular heartbeat

A racing or irregular heartbeat can be a normal reaction to stress or caffeine consumption. However, regular or unprovoked heart palpitations may indicate that the heart is under duress. If the heart is not getting enough oxygen-rich blood, it can start to beat irregularly. If you experience palpitations along with dizziness, chest pain, or shortness of breath, you should see a doctor right away.

8. Shortness of Breath

If suddenly climbing stairs or performing other everyday activities becomes a problem, then there may be a heart issue. Shortness of breath usually occurs with heart conditions because the circulation is not adequate and less oxygen is provided to the lungs. This symptom can occur either with or without chest pain and is an important indicator of the presence of underlying heart disease. If you find yourself experiencing sudden unexplained breathlessness, then seek a healthcare provider as soon as possible.

When to Seek Medical Attention

Early detection of these symptoms and early intervention can help avoid a life-threatening heart attack. You should visit a doctor if you feel the following symptoms:

• Symptoms induced by exertion and relieved by rest
• The simultaneous onset of several warning signs, including weakness, dizziness, and nausea
• Personal or family history of heart disease, hypertension, diabetes, or smoking

Preventing Heart Attacks: Proactive Steps for Heart Health

Although heart attacks may come out of nowhere, lifestyle plays an important role in reducing a patient's risk; here are some heart-healthy habits to consider:

Take on a Heart-Healthy Diet: Focus on consuming whole foods, lean proteins, healthy fats, and fiber-rich fruits and vegetables. Try to limit processed foods, saturated fats, and added sugars.

Stay Active: Engage in at least 30 minutes of moderate physical activity most days of the week to strengthen your heart and improve blood circulation.

Smoking. Smoking is probably the single largest risk factor for heart disease. If you are a smoker, quitting can easily be the single best thing you can do to improve your heart health.

Deal with Stress: Chronic stress leads to heart disease. Relaxed people through various relaxation techniques including yoga, meditation, and even deep breathing, have lesser stresses.

Regular health checks Monitor blood pressure, cholesterol levels, and blood sugar on a regular basis. The risk factors' early detection can help avoid serious complications.

If you believe having a healthy body mass index (BMI) means you have a low risk of heart disease, you may be wrong. A new study suggests that abdominal fat may predict cardiovascular disease risk better than BMI alone.

The study, published in the Journal of the American College of Cardiology (JACC), found that failing to account for waist circumference (WC) or waist-to-hip ratio (WHR) may lead to misclassification of cardiovascular disease risk.

“Indeed, it appears that WC and WHR reclassify risk defined by traditional BMI thresholds,” said Michael J. Blaha, director of clinical research at the Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease.

“We saw individuals with clinically determined normal weight who had elevated central adiposity and high WHR, associating them with higher risk across most outcomes,” Blaha added.

Why BMI Alone May Not Predict Heart Risk

BMI is calculated by dividing weight in kilograms by height in meters squared and is commonly used to diagnose overweight and obesity. However, BMI does not show where body fat is distributed.

• Visceral fat surrounds the internal organs in the abdominal area and is associated with chronic conditions such as heart disease and diabetes.
• Subcutaneous fat is located directly under the skin and is not as strongly associated with these conditions.

What Did the Study Find?

The study examined whether adding WC and WHR to BMI could better predict future cardiovascular risk. Researchers looked at more than 260,000 people over an average of 20 years. They found that central adiposity could identify cardiovascular risk that BMI alone may miss.

Among people classified as having normal weight by BMI:

• 5% had high waist circumference
• 18% had high waist-to-hip ratio

• 39% had high waist circumference
• 40% had high waist-to-hip ratio

• 9% had low waist circumference
• 45% had low waist-to-hip ratio

People with normal weight or overweight who had clinically defined high WC or WHR had a 15%–50% greater risk for most heart problems.

People with obesity and low WC did not have a significantly different risk of outcomes compared with those who had normal weight and low WC, except for all-cause mortality, for which their risk was significantly lower.

“Our findings emphasize the critical role of identifying elevated central adiposity, even in individuals with a normal BMI or with a BMI in the overweight range. Relying solely on BMI may result in misclassification of cardiovascular risk across a wide range of cardiovascular outcomes,” said Zeina A. Dardari, lead author of the study.

“We encourage clinicians to consider central adiposity distribution across the entire BMI spectrum when evaluating cardiovascular risk in primary prevention settings,” she added.

What Were the Study's Limitations?

The researchers did not have information on several factors that can influence cardiovascular disease risk, including:

• Physical activity
• Diet
• Genetic risk for obesity

The study also included only one assessment of waist circumference and waist-to-hip ratio. This limited the researchers' ability to understand how changes in abdominal fat accumulation over time may influence cardiovascular disease risk.

Organ donation is one of the most profound ways in which we can give the gift of life to another person. To raise awareness about organ donation, it is important address common myths and encourage more people to consider pledging their organs.

India has a large number of patients waiting for organ transplants, including transplants of the liver, kidney, heart, pancreas, intestine and other organs and tissues.

Despite the significant need, organ donation rates remain low, with lack of awareness and several misconceptions continuing to be major barriers. One organ donor can potentially save multiple lives. However, for this to happen, it is important that people understand the process and make an informed decision about organ donation during their lifetime.

Busting Common Myths About Organ Donation

1. “My religion does not permit me to donate my organs.”

2. “Organs can only be donated after the heart stops beating.”

For most organs, donation after brain death is possible when the brain has permanently stopped functioning, but the heart is still beating, which generally occurs in an intensive care setting. Corneas can also be donated after death within a limited time period. This is why pledging your organs during your lifetime and discussing your decision with your family is important.

3. “Organ donation will disfigure or mutilate the body.”

Organ retrieval is performed by trained medical specialists in an operating theatre. The surgical incision is carefully closed after the procedure, and the body is not mutilated.

4. “I can buy a kidney or liver for my family member.”

5. “If I donate a kidney, I will become weak or handicapped.”

A healthy person who is found suitable for living kidney donation through the required medical evaluation can generally continue their normal life after donation. The remaining kidney is capable of maintaining normal kidney function.

6. “A kidney donor has to take lifelong medicines.”

Kidney donation does not mean that a healthy donor has to take lifelong medication simply because they have donated a kidney. Some pain medication may be required during the initial recovery period, while the remaining healthy kidney continues to perform its function.

7. “I will have severe dietary restrictions after donating a kidney.”

According to the source material, kidney donors do not generally need specific dietary restrictions solely because they have donated a kidney, as the remaining kidney continues to maintain normal kidney function.

8. “I will not be able to have children after donating a kidney.”

Both men and women who donate a kidney can have children. For women, the source recommends waiting one year after donation before becoming pregnant to allow the body to recover completely.

9. “I am over 60, so I am too old to donate.”

Age alone does not determine whether someone can donate. The health of the donor and the condition of the organs are important considerations, and suitability is determined through medical evaluation.

What Can We Do To Encourage Organ Donation?

• Consider pledging your organs during your lifetime and communicate your decision clearly to your family.

• Talk to your family, friends and colleagues about organ donation and help dispel common myths.

• Encourage community organisations to participate in creating awareness around organ donation.

• Do not assume that you are medically unfit to donate. A team of medical experts evaluates the donor and determines suitability.

• Organ donation is a completely voluntary decision. No individual should be pressured into donating an organ.

• Patients waiting for an organ transplant should approach a licensed transplant hospital and complete the necessary registration formalities, including through the NOTTO system.

Organ donation is ultimately about giving someone another chance at life. We should not take our organs with us; they can be used to save lives and give hope to those waiting for a transplant.

Anemia remains one of the least talked about threats to a safe pregnancy in India. The National Family Health Survey-5 data shows that 52.2% of pregnant women in India were anemic. This translates to at least one in two expectant mothers entering pregnancy with insufficient hemoglobin to meet her own and her baby’s needs.

Pregnant women with iron-deficiency anemia may feel unusually tired, weak or short of breath. Some women may suffer from dizziness, headaches, palpitations or reduced ability to concentrate. However, symptoms can be subtle and this is why routine antenatal screening is important even if the woman feels well.

Left unaddressed, it raises the risk of preterm birth, low birth weight, postpartum haemorrhage, and maternal fatigue severe enough to affect daily functioning and recovery after delivery.

Severe anaemia can also reduce a woman's ability to tolerate blood loss during delivery, making even an otherwise uncomplicated birth potentially more challenging.

Why pregnancy makes it worse? Well, blood volume expands by nearly 50% during pregnancy, and the growing fetus draws heavily on maternal iron stores, especially in the second and third trimesters. Most Indian women begin pregnancy with iron stores already depleted by poor dietary intake, frequent pregnancies, or heavy menstrual blood loss. So, the added demand tips many into overt anaemia.

Do's:

1. Start Antenatal Care early. You should get a baseline haemoglobin test at your first antenatal visit, and repeat this each trimester or more if needed.

2. Iron and folic acid tablets must be taken in accordance with the prescription given. It is best to start with them before conceiving or as soon as possible in the pregnancy process, preferably in discussion. The dietary consumption may not always be sufficient to cater to the increased demands during pregnancy.

3. Pair iron-rich foods with vitamin C. A squeeze of lemon with dal or leafy greens meaningfully improves absorption. Indian gooseberry (amla), guava, oranges and tomatoes improve absorption of non-heme iron from plant based foods.

4. Include iron-dense foods regularly like leafy greens, jaggery, dates, legumes, eggs. If non-vegetarian, eat lean meat or fish, meat or poultry.

5. Treat underlying causes. Get heavy periods, worm infestations or unexplained fatigue evaluated before conception if possible.

6. Ask about your ferritin level, not just haemoglobin, since ferritin reveals depleted iron stores earlier.

Anaemia is not always caused by iron deficiency. B12 or folic acid deficiency, problems with haemoglobin production, infections, and many other medical conditions can also be contributing factors.

Don'ts:

1. Do not stop iron supplements simply because you feel better. Treatment usually needs to continue for the recommended period to replenish iron stores.

2. Don't take iron tablets with tea, coffee or milk. These block absorption. Space them at least an hour apart.

3. Do not skip supplements because of nausea or constipation. Ask your doctor for alternate formulations instead of foregoing the supplements.

4. Don't assume fatigue is ‘normal pregnancy tiredness’ without a haemoglobin check. Persistent breathlessness, dizziness or a racing heart need evaluation.

5. Don't self-medicate with over-the-counter iron doses. Both too little and too much iron can cause harm.

6. Don't ignore mild anaemia on the assumption that it will ‘sort itself out’. It typically worsens as pregnancy progresses and has to be actively treated.

Anemia in women is mostly preventable and treatable early. Regular antenatal check ups, proper supplementation, balanced diet and timely treatment can go a long way in reducing its impact on the mother and baby. The key message is simple, really. Screen early, do not wait for symptoms, treat appropriately and maintain adequate iron stores throughout pregnancy.
