As sudden cardiac arrests become common in young people, experts urge the need for these medical tests before starting gym
Particularly for individuals over 30, those with a family history of heart disease, or people who are just starting, or restarting, intensive physical activity like gym workouts, these tests can help to detect underlying heart conditions that may otherwise go unnoticed until they become life-threatening, said Dr Narander Singla, lead consultant, internal medicine, CK Birla Hospital, Delhi.
Here's a breakdown and explanation of five tests that should be done
1. ECG (Electrocardiogram)
An ECG records the electrical activity of the heart and helps detect arrhythmias (irregular heart rhythms), conduction blocks, or signs of prior silent heart attacks. 'While not definitive alone, it provides a good baseline for identifying abnormalities in heart rhythm or conduction that may become dangerous during strenuous activity,' said Dr Singla.
2. 2D Echo (Echocardiography)
This is a non-invasive ultrasound of the heart that allows doctors to visualise the heart's structure and function. 'It is especially helpful in identifying conditions like Hypertrophic Cardiomyopathy (HCM), a thickening of the heart muscle that often goes undiagnosed and can lead to sudden cardiac arrest during intense physical exertion. It also helps assess valve function, chamber sizes, and overall heart pumping ability,' said Dr Singla.
3. TMT (Treadmill Test or Stress Test)
A TMT evaluates how your heart performs under stress (exercise). It can help reveal issues like exercise-induced arrhythmias or restricted blood flow to the heart (which may not be evident at rest). 'This is especially useful for people who plan to do high-intensity workouts or weight training, as it simulates physical stress in a controlled setting,' said Dr Singla.
4. Cardiac biomarkers – Troponin & NT-proBNP
These blood tests detect subtle damage or stress to the heart muscle. 'High-sensitivity troponin is a marker for silent myocardial injury, while NT-proBNP indicates stress or stretching of the heart walls. Elevated levels, even without symptoms, can be an early warning sign of cardiovascular disease,' said Dr Singla.
5. Hs-CRP and ESR (Inflammatory Markers)
These markers can help detect systemic inflammation, which is a contributing factor in atherosclerosis (plaque buildup in arteries). High levels of high-sensitivity C-reactive protein (hs-CRP) are associated with an increased risk of heart attack and stroke, even in people with normal cholesterol.
6. Lipid Profile + HbA1c (Metabolic Health Tests)
A lipid profile evaluates cholesterol and triglyceride levels, which are directly linked to cardiovascular risk. Dr Singla explained that HbA1c gives a picture of your average blood sugar levels over the past 3 months and helps detect prediabetes or diabetes, conditions that increase heart disease risk significantly. Together, they help assess metabolic syndrome, which is often silent but increases cardiac risk, said Dr Singla.
Moreover, a vitamin D and B12 test helps to check if any deficiencies could affect energy, bone strength, and muscle function, said Dr Agarwal. 'These tests should be taken by the gym-goers without fail on a priority basis. Initiate any workout routine only after you get a go-ahead from the expert, after knowing the test results. Be attentive when it comes to your overall well-being,' said Dr Agarwal.
Intense physical stress can unmask these problems, especially in people who may not have exercised in years or have underlying risks. Dr Agarwal noted that these tests are 'not luxury options', they are preventive screenings that could literally save lives. 'They offer a chance to catch conditions like HCM, arrhythmias, ischemic heart disease, or silent heart strain before a fatal event occurs,' said Dr Agarwal.

As sudden cardiac arrests become common in young people, experts urge the need for these medical tests before starting gym
Sudden cardiac arrest in seemingly fit individuals often results from undiagnosed heart conditions. Hence, before starting any gym or workout routine, experts recommend that certain tests be done to understand the health status. Doing so will also help you to understand if the body is ready for physical exertion, said Dr Manjusha Agarwal, senior consultant, internal medicine, Gleneagles Hospital, Parel, Mumbai. Particularly for individuals over 30, those with a family history of heart disease, or people who are just starting, or restarting, intensive physical activity like gym workouts, these tests can help to detect underlying heart conditions that may otherwise go unnoticed until they become life-threatening, said Dr Narander Singla, lead consultant, internal medicine, CK Birla Hospital, Delhi.

The silent heart condition putting young adults at risk: What is Hypertrophic Cardiomyopathy, and what are the overlooked symptoms
On the surface, it all looks nice and shiny; energetic and unstoppable, even. However, a threat seems to be lurking around the corner and creeping up silently in the lives of young adults. What is it? It's called hypertrophic cardiomyopathy (HCM) . Often symptom-free and misunderstood, this genetic heart condition thickens the heart muscle, especially in the left ventricle, making it harder to pump blood and increasing the risk of dangerous heart rhythms and sudden cardiac death. And mistake not for its 'silent' nature, it can strike without warning. Characterized by thickened heart muscle, HCM reduces the heart's pumping efficiency and often hides behind vague symptoms like shortness of breath, fatigue, or fainting. Because many affected individuals are asymptomatic or misinterpret symptoms as stress or poor fitness, this condition often goes unnoticed until a serious event, such as sudden cardiac arrest. What Is Hypertrophic Cardiomyopathy? HCM is a genetic heart condition in which the heart muscle becomes abnormally thick, often impacting the wall between the pumping chambers, known as the septum. This thickening can narrow the pathway for blood to leave the heart (obstructive HCM) or simply make the heart stiffer and less able to fill and pump efficiently (non-obstructive HCM). by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Remember Him? Sit Down Before You See What He Looks Like Now 33 Bridges Undo This increased muscle mass can also disturb the heart's electrical system, raising the risk of dangerous arrhythmias and, tragically, sudden cardiac death, even in otherwise healthy young people. While many people with HCM live normal lives, the condition is the leading cause of sudden cardiac death (SCD) among young athletes and active adults under 35. Why it's called the 'silent' heart condition Many individuals with HCM never experience noticeable symptoms ; some estimates suggest up to 50% may remain symptom-free or only mildly symptomatic. Others may dismiss faintness, chest tightness, or breathlessness as normal fatigue or stress. HCM is alarmingly common among young adults and athletes; studies show it's the leading cause of sudden cardiac death in young athletes, accounting for nearly one in four such cases. Why young adults are especially at risk Young people with undiagnosed HCM may seem perfectly healthy, but they experience hidden danger. Older research suggested mortality rates up to around 6% per year in children with HCM, often due to SCD. However, recent advancements in treatments such as implantable defibrillators (ICDs), targeted medications, and surgical options have improved outcomes dramatically. A study tracking nearly 500 patients aged 7 to 29 found a lower annual HCM-related death rate of about 0.5%, thanks to early intervention and modern treatment strategies. Furthermore, family history is a key clue. HCM is inherited in an autosomal dominant pattern, meaning a child has a 50% chance of inheriting it from an affected parent. Even elite athletes with no symptoms can suffer sudden cardiac arrest, as happened to high school wrestler J.J. at age 18 and an NBA player, Jared Butler, who learned of his diagnosis during a routine physical at 18 – cases that have drawn much attention to the 'silent' killer. Overlooked and subtle symptoms Many individuals with HCM don't experience obvious symptoms or may ignore them: Shortness of breath during exertion or even at rest Chest pain or angina-like discomfort during activity Heart palpitations, dizziness, or fainting episodes Fatigue, swelling in the legs or abdomen, and unusual lightheadedness These signs are often dismissed as stress, poor fitness, or non-serious ailments; delay in diagnosis is common. In some cases, sudden death is the first obvious indication of HCM. Screening and early detection: Why it matters Because HCM is often inherited in an autosomal dominant pattern, family history matters. Screening methods include listening for heart murmurs, plus diagnostic tools like ECG, echocardiograms, MRI, and genetic testing. Early treatment can slow or prevent disease progression. A clinical trial found that young adults treated early with valsartan (a blood pressure medication) showed reduced physical progression of HCM vs. placebo. Treatments of HCM While HCM can't be cured, it can be effectively managed. Management of HCM is likely to include: Medications like beta-blockers, calcium channel blockers, disopyramide, and the newer FDA-approved drug mavacamten. Implantable cardioverter-defibrillators (ICDs) for those at high risk of SCD. In severe cases, surgical interventions, like septal myectomy or alcohol septal ablation, can relieve obstruction. Shared decision-making with your medical team to tailor treatment based on your age, goals, and risk factors. Lifestyle changes, including avoiding vigorous competitive sports, can reduce risk and improve quality of life. Thanks to modern therapies, most individuals have a normal life expectancy and manage well with proper monitoring and support. Living with HCM: What you should do Be alert to subtle symptoms: don't brush off fainting, fatigue, or shortness of breath. Know your family's heart history: First-degree relatives should get screened. Get early and accurate testing if at risk: ECG, echo, MRI, and genetics can offer clarity. Work closely with your care team: Use shared decision-making to choose the best management path. Stay informed on new treatments: Medications like mavacamten and minimally invasive procedures offer promising options. The parting thought Hypertrophic cardiomyopathy is a silent, and often deadly, heart condition that hides behind normal activity, especially in the young and fit. But with awareness, screening, and early action, lives can be protected. If you or a loved one experiences unexplained breathlessness, fainting, chest pain, or palpitations, or has a family history of heart disease, talk to a doctor. A simple test could be the difference between tragedy and prevention. Catching HCM early can make it manageable, not deadly. How To Identify Heart Attack

Starting gym? Cardiologist recommends five tests to reduce the risk of heart attack in young adults
In recent years, gyms have become more than just places to build muscle; they've become potential hotspots for sudden cardiac events. With heart attacks during workouts making headlines more frequently, doctors are urging fitness enthusiasts to take precautionary health screenings seriously, especially before beginning or intensifying a workout routine. Why Heart Attacks Happen During Exercise Heavy and strenuous workouts can cause a sharp spike in blood pressure if not approached gradually and correctly. Increased blood pressure during a tough gym session is natural, but if someone already has a weak heart or blocked arteries, this spike can be dangerous. Undiagnosed conditions like coronary artery disease, arrhythmias, or hypertrophic cardiomyopathy often go unnoticed until triggered by physical exertion. Lifestyle habits such as smoking, poor diet, or unmanaged diabetes compound the risk, even in younger individuals What the doctor says Dr. Obaidur Rahman, an Orthopedic and Sports Surgeon (MS, RML), recently shared a tragic case that underscores the importance of preventive screening. One morning, a man collapsed on a treadmill after a regular cardio session. By the time he reached the emergency room, his heart had already stopped twice. Despite all efforts, he couldn't be revived. Postmortem findings revealed he had Hypertrophic Cardiomyopathy (HCM), a condition where the heart muscle becomes abnormally thick, making it harder for the heart to pump blood. It's a silent condition that can be easily detected through a simple scan, and if caught early, lives can be saved. 5 essential tests for gym-goers If you're over 30, have a family history of heart disease, or are beginning a new fitness regime, these tests are not optional; they are critical. ECG (Electrocardiogram) A basic but powerful test, the ECG records the heart's electrical signals. It can detect abnormalities like arrhythmias and help predict the risk of sudden heart failure. It's painless, quick, and a good baseline test for anyone starting workouts. 2D Echo (Echocardiography) This ultrasound scan provides live images of the heart, assessing its structure and function. It helps spot conditions like HCM, valve disorders, and other heart defects that might otherwise go unnoticed. TMT (Treadmill Test or Stress Test) This test evaluates how your heart performs under physical stress. You'll be asked to walk or run on a treadmill while your heart activity is monitored. It's especially useful in revealing blocked arteries or poor blood flow that only shows up during exertion. Troponin and NT-proBNP These blood tests check for early signs of cardiac strain or injury. Elevated levels could indicate silent heart damage or stress that may not yet be showing symptoms. hs-CRP and ESR(Erythrocyte Sedimentation Rate) Inflammation plays a key role in cardiovascular disease. While ESR measures general inflammation, hs-CRP is more specific to heart-related inflammation. High readings could signal higher risk for heart issues in the future. Lipid Profile + HbA1c These tests check cholesterol and long-term blood sugar levels. Elevated cholesterol and uncontrolled diabetes are two major contributors to heart disease and stroke. Early detection allows for dietary and medical intervention. 'These tests are not a luxury.' Many people assume these are 'extra' or advanced screenings meant only for the elderly or elite athletes. But as Dr. Rahman stresses, 'These are life-saving tests. Especially if you're over 30, push yourself hard in the gym, or have a family history—please, get checked first.'
