Heart attacks are a leading cause of death worldwide, and while we often associate them with dramatic chest pain, numerous lesser-known symptoms could signal an impending cardiac event. This is why it’s crucial to be aware of these silent warnings, as early detection and intervention can be life-saving.
Many heart attack cases may involve symptoms that the individuals did not immediately recognise as heart-related. Dr Bhavini Shah, a GP with a pharmacy, has highlighted some of these subtle signs that should not be ignored.
1. Widening of fingernails
One such sign is digital clubbing, an unusual thickening and widening of the fingernails. This occurs when oxygenated blood fails to reach the fingers adequately, causing an overproduction of nail tissue.
While this might seem like a cosmetic issue, it’s actually a red flag for underlying cardiovascular problems.
2. Grey ring around the iris
Another symptom that often goes unnoticed is the presence of a grey ring around the coloured part of the eye. This fatty halo can indicate high cholesterol levels, which are a significant risk factor for coronary heart disease.
Research shows that about 45 per cent of people over the age of 40, and 70 per cent over 60, exhibit this sign, yet many are unaware of its implications.
3. Swollen legs
Swollen legs, or oedema, is another symptom that is frequently overlooked. This swelling occurs when a weakened heart cannot pump blood effectively, leading to fluid buildup in the legs and feet.
Despite its significance, less than half of the population recognises leg swelling as a symptom of heart disease.
4. Chest pain
Chest pain remains the most recognised symptom, with 80 per cent of people identifying it as a major warning sign. However, it’s important to understand that chest pain can manifest in various ways, including pressure, tightness, squeezing, or heaviness in the chest.
If you experience such discomfort, it’s essential to seek medical attention immediately.
5. Irregular heart rhythms
Shortness of breath and irregular heart rhythms are also common indicators of heart disease. If the heart isn’t pumping enough blood, fluid may accumulate in the lungs, making it difficult to breathe.
While 77 per cent of people are aware of this symptom, only 70 per cent recognise irregular heartbeats as a potential warning.
6. Extreme fatigue
Extreme fatigue is another red flag that is often dismissed. If you find day-to-day activities or mild exercise exhausting, it could be a sign that your heart is struggling. Surprisingly, only 66 per cent of people surveyed were aware of this symptom.
In Australia, heart attacks claim an average of 19 lives each day—roughly one life lost every 74 minutes—making it one of the leading causes of hospitalisation and death in the country, according to the Heart Research Institute (HRI).
To combat this, Dr Shah emphasises the importance of lifestyle changes to prevent heart disease. Reducing fat intake, following a high-fibre, low-fat diet, limiting salt, and avoiding saturated fats are all dietary measures that can help.
Physical activity is another crucial factor in heart health. According to the British Heart Foundation, staying active can reduce your risk of heart disease by up to 35 per cent. Whether it’s walking, cycling, swimming, or attending a fitness class, regular exercise helps regulate blood pressure and lower cholesterol levels.
Quitting smoking and moderating alcohol consumption are also vital steps. Smoking damages the arteries and interferes with cholesterol processing, while excessive alcohol intake over time can increase the risk of heart disease or stroke.

I had two heart attacks a few years ago with none of these symptoms, my symptoms were heart burn and a pain through both elbow joints like someone poking a hot needle threw them and because they weren’t like anything we have been told to watch out for I didn’t take any notice of them just took something for the heart burn the first time and it went away a week later it happened again, done the same thing but this time it didn’t go away so went to the hospital for something stronger heart burn, before I could say anything the triage nurse rushed me in because I was holding my chest, they done a blood test and that’s when the doctor told me I have had two heart attacks, so it goes to show medicos don’t know all the signs.
