You could spot a heart attack days before it strikes: Delhi-based doctor reveals one overlooked symptom that might save your life

Most people imagine heart attacks as sudden, intense events that strike without warning — crushing chest pain, cold sweats, and breathless panic. But according to Dr. Obaidur Rahman, a physician currently resident at Delhi's Ram Manohar Lohia Hospital the warning signs can appear days before the attack. The problem is, as he cautions, “92% of people ignore them.”

A Silent Signal Before the Storm

Dr. Rahman’s post, which has garnered wide attention for its urgency, focuses on a condition called orthopnea — a subtle but potentially life-saving indicator that the heart might be in distress.

Orthopnea occurs when a person finds it difficult to breathe while lying flat. “When the heart weakens, blood backs up into the lungs,” Dr. Rahman explained in his Instagram video. “The moment you lie flat, gravity stops helping you breathe and you wake up suffocating, restless, drenched in sweat.”


Many, he said, mistake this breathlessness for acidity, stress, or anxiety, when in fact, it’s the body’s cry for help.

How It Works: When Gravity Turns Against You

Under normal conditions, lying down doesn’t affect breathing. But for someone with underlying heart issues, the shift in gravity redistributes blood from the legs to the chest. This increases pressure in the lungs, making it harder to breathe.

Dr. Rahman emphasized that this warning should never be ignored: “If you’ve ever had to sleep propped up on pillows just to breathe better, get yourself checked.”

He illustrated the point with a story — a seemingly healthy 29-year-old who brushed off mild breathlessness for a few nights. Three days later, he collapsed at work due to a massive heart attack. “By the time help arrived,” Rahman wrote, “it was too late.”

Modern Lifestyles Are Fueling the Risk

The doctor also linked rising cases of early heart trouble to modern work culture. “It’s happening to a generation raised on late nights, deadlines, skipped meals, energy drinks, and zero recovery,” he warned. “Your heart doesn’t care about your ambition. It only cares about your oxygen.”

Health experts have echoed similar concerns — the combination of high stress, poor sleep, and processed diets is pushing younger people toward cardiac complications once considered rare before middle age.

Listening to the Body Before It’s Too Late

Dr. Rahman’s message, underscores that prevention often lies in attention. Orthopnea, fatigue, or sudden breathlessness may not sound dramatic, but they can serve as crucial early alarms.

Medical professionals advise that anyone experiencing these symptoms should seek prompt evaluation, especially if combined with chest discomfort, anxiety, or unexplained sweating.

As Dr. Rahman concluded, “That’s not stress. That’s your body begging you to listen.” Ignoring such signs, he warned, could mean overlooking the only window to prevent a life-threatening event.
