Heart Attack Symptoms: 3 silent heart attack warnings you are probably overlooking |

Heart disease remains one of the leading causes of death globally still, many do not realise is that it often begins quietly with small clues that our body gives off, long before a major event. In his latest Instagram post, cardiovascular research scientist Dr James DiNicolantonio explained, “Recognising these subtle, early signs can make a significant difference in preventing severe cardiovascular events.” Here are the three early red-flags he emphasises and how you can respond to them –

Dr DiNicolantonio noteed that erectile dysfunction (ED) may serve as an early warning for cardiovascular trouble and cautioned, “About half of people with heart disease experience erectile dysfunction and it can precede heart disease by up to five years.” Since blood-flow issues in smaller arteries (such as penile arteries) often mirror what can be happening in coronary arteries, ED may reveal hidden cardiovascular risk. If you are experiencing ED, especially with no obvious lifestyle cause, discussing it with a clinician is wise.

One often dismisses it as “getting out of shape” or “just tired” but Dr DiNicolantonio flags dyspnoea or shortness of breath with light exertion as another key sign and warned, “If climbing a few stairs or doing light exercise leaves you unusually winded, it’s a signal that your heart may be struggling.” Pay attention, whether you are parents juggling school runs or professionals managing long days or anyone who notices breathlessness on simple tasks. It may mean your heart is less efficient at pumping blood or your lungs are getting overburdened.

Feeling Breathless or Swollen? These Unexpected Symptoms May Reveal Heart Trouble

Fluid retention in the lower limbs is easy to dismiss as new shoes are too tight or blame it on the long-haul flight but this symptom may hide something more serious. The expert revealed, “Swelling in the feet, ankles, or lower legs can indicate heart failure or kidney dysfunction. Fluid retention is a common but often overlooked symptom of cardiovascular issues.” If you notice persistent swelling (especially alongside breathlessness or fatigue), it is time to see a doctor. It could indicate your heart isn’t effectively pumping blood, causing fluid to pool.

Medical research supports the idea that the heart sends whispers long before it crashes into a major event. For instance, a 2023 review from Harvard Health Publishing identified swelling, fatigue and breathlessness as early heart-failure signals. It is a general tendency for people to ignore heart failure symptoms and attribute them to just getting older but noticing these lesser-known symptoms and starting conversations early may lead to interventions (lifestyle, medical or both) that delay or prevent serious disease.

Heart disease is no longer just a condition of the “built-up bricks” of age. It can flick a light switch early, sometimes via unusual signs. Swelling in ankles, unexplained breathlessness or a shift in sexual health might be your body’s early alert. As Dr DiNicolantonio reminds us, acting when these signs appear can change the story. Wait for the crash? Or catch the whisper first. Tune in. Act early. Your heart will benefit.Note: The information provided in this article is for educational purposes only and is not intended as medical advice.
