While severe heart conditions are often associated with older age or sudden emergencies, the heart frequently gives subtle warnings long before serious issues develop. With World Heart Day approaching on 29 September, Dr Oliver Guttmann, a consultant cardiologist at The Wellington Hospital, part of HCA Healthcare UK, has identified four discreet signs that could signal the need for a cardiac check-up.
Chest discomfort – Dr Guttmann explains that chest pain rarely feels like the dramatic 'crushing' sensation seen in films. Instead, it may present as pressure, heaviness, or tightness across the chest, sometimes described as a band squeezing the chest. It can also mimic heartburn or radiate to the arms, shoulders, neck, jaw, or back. These symptoms may indicate angina, which signals underlying coronary artery disease and increases heart attack risk if untreated.
Shortness of breath – Feeling breathless during routine activities, such as climbing a single flight of stairs or bending down to tie shoes, may indicate the heart is struggling to pump blood efficiently. Warning signs include needing extra pillows to sleep comfortably, waking suddenly gasping for air, or breathlessness that worsens over days or weeks. This can occur when fluid backs up into the lungs, often associated with heart failure.
Unexplained fatigue – Heart-related fatigue is persistent, extreme, and not relieved by rest. It may manifest as exhaustion after simple chores like vacuuming, needing frequent daytime naps, or sudden weakness when carrying groceries. Women, in particular, may notice unusual fatigue as one of the earliest signs of heart disease, often without chest pain.
Heart palpitations – Frequent palpitations or irregularities should not be ignored. Signs include fluttering or 'skipping' sensations, sudden pounding or racing heartbeats even at rest, or feeling the heart 'flip' unexpectedly. These can indicate arrhythmias such as atrial fibrillation, which increases the risk of stroke. Dr Guttmann advises that even mild or intermittent symptoms should prompt a medical review, as early detection can prevent serious complications.
