Recent cases of sudden cardiac arrests among individuals with normal health check-ups have prompted cardiologists to warn that standard tests do not guarantee heart safety. Dr. Navida Batra, an interventional cardiologist at Metro Hospital in New Delhi, explains that while blood tests, lipid profiles, and glucose levels are important, they do not capture the full spectrum of cardiovascular risks. Heart attacks can occur due to factors like unstable plaques in the arteries, which may not be detected in routine tests. Lifestyle factors such as high blood pressure, smoking, and obesity, along with genetic predispositions, also play significant roles in heart health. Advanced diagnostic markers like lipoprotein(a) and imaging tools can provide deeper insights into potential risks. Cardiologists are increasingly seeing younger patients with heart attacks despite normal test results, indicating the limitations of relying solely on traditional screenings. Symptoms such as chest pain and unusual fatigue should not be overlooked, as early medical intervention can be crucial. Maintaining a heart-healthy lifestyle and regular check-ups are essential for proactive heart health management.
