Cholesterol report alone cannot predict heart attack risk, says cardiologist
New Delhi: For many people, cholesterol levels become the first thing they check while assessing heart health. A high cholesterol report often creates immediate concern, while a normal reading can bring a false sense of security. However, heart attack risk depends on several factors and cannot be judged through cholesterol alone, says Dr Amar Singhal, Director, Cardiology, Sri Balaji Action Medical Institute, Delhi.
The doctor explains that conditions such as diabetes, high blood pressure, smoking, obesity, stress and family history also influence cardiovascular health. According to him, understanding the complete risk profile is important for timely prevention. Regular screening, healthy lifestyle choices and medical guidance play a key role in reducing the chances of serious heart complications.
Cholesterol and heart attack risk
Dr Amar Singhal explains that cholesterol remains an important marker, especially high LDL or “bad cholesterol”, which can contribute to plaque buildup in arteries. However, it is only one part of the overall picture.
“Heart disease is more complex, and focusing only on cholesterol may cause people to miss other important warning signs,” he said.
A person with normal cholesterol levels may still face a higher risk if other factors such as uncontrolled diabetes, high blood pressure, smoking, obesity, poor sleep, inflammation, unhealthy eating habits or lack of physical activity are present.
Why heart attacks happen despite normal cholesterol
Heart attacks often occur when plaque inside an artery ruptures and a clot forms, blocking blood flow. Dr Singhal stated this process is not always reflected only through cholesterol numbers.
This is why doctors assess overall cardiovascular risk instead of depending on a single test result. A detailed evaluation helps identify concerns that may otherwise go unnoticed.
Signs that need attention
Symptoms such as chest pain, breathlessness, heaviness in the chest, pain spreading to the arm or jaw, unexplained sweating, dizziness or extreme fatigue should not be ignored, even when cholesterol levels appear normal.
Complete heart care approach
A proper heart health checkup may include blood pressure monitoring, blood sugar tests, lipid profile, weight assessment, ECG when advised, and discussion around lifestyle habits and family history.
For some people, doctors may recommend additional tests depending on symptoms and individual risk factors.
Dr Singhal emphasised that prevention requires a wider approach. Cholesterol control remains important, but timely screening, risk assessment, lifestyle correction and medical advice together help protect heart health.
Heart health cannot be measured through one report alone. Looking at multiple risk factors helps detect problems early and supports better prevention.
