Early signs of heart disease can be subtle and are often mistaken for stress or ageing, but a cardiologist says recognising them early can make a significant difference
Dr Francesco Lo Monaco
A cardiologist has warned that early indicators of heart trouble can manifest in subtle ways, leading many to overlook them until the situation becomes more severe. While chest discomfort is commonly regarded as the textbook sign of cardiac disease, medical professionals say numerous patients encounter more discreet symptoms initially, which are regularly attributed to stress, the ageing process or poor fitness levels.
Dr Francesco Lo Monaco, a private cardiologist practising in London, explained that identifying these less apparent warning signals early on can prove crucial. He said: “Heart problems do not always begin with dramatic symptoms. In many cases, the body gives more subtle warning signs first, but people often dismiss them because they seem harmless or unrelated.”
Unusual breathlessness
Among the most frequently dismissed signs is developing unexpected shortness of breath while carrying out routine everyday tasks. This may occur when the heart is finding it difficult to circulate blood effectively throughout the body.
Dr Lo Monaco stated: “People often put this down to getting older, being unfit or simply tired. But if someone notices they are suddenly struggling more with stairs, walking or light activity, it is something that should be assessed.” He emphasised that breathlessness, which is recent, deteriorating or excessive relative to one’s level of exertion, is especially critical not to disregard, reports MyLondon.
Persistent fatigue
Experiencing unusual tiredness over extended periods may also be connected to cardiac issues, particularly when it emerges without an obvious cause. “When the heart is not functioning optimally, the body may not be getting the oxygen it needs efficiently,” Dr Lo Monaco explained.
“That can leave people feeling persistently fatigued even if they are sleeping normally.” He noted that this warning sign is frequently overlooked because exhaustion is such a common part of everyday life.
Mild chest discomfort or an unexplained left arm pain
While severe chest pain is commonly understood as requiring urgent medical attention, milder discomfort or unexplained left arm pain often goes unnoticed. This could manifest as tightness, pressure, heaviness or an odd sensation in the chest that appears intermittently.
Dr Lo Monaco noted: “Not all heart-related symptoms are intense. Some people experience very subtle discomfort that they dismiss as indigestion, muscle strain or anxiety.” He emphasised that symptoms which persist, return repeatedly or happen during physical activity warrant medical evaluation.
When to seek help
Medical professionals emphasise that these warning signs don’t necessarily indicate heart disease, though patterns and frequency are significant. “If symptoms are new, worsening or don’t feel normal for you, it’s important to seek medical advice rather than ignore them,” Dr Lo Monaco said.
“Early assessment can help identify problems before they become more serious.” He stressed that prevention and awareness are crucial for maintaining cardiovascular health. “The earlier heart issues are recognised, the better the opportunities for treatment and long-term outcomes,” he said.
