Heart Attack: 4 Warning Signs That Can Appear Days Before

A heart attack doesn't always come without warning. According to specialists cited by HuffPost, certain warning signs can be felt days or even weeks beforehand, yet they are often overlooked.

Chest pressure or discomfort

One of the best-known signs is angina — chest pain or a feeling of pressure that can occur intermittently and is linked to the gradual narrowing of the arteries. Dr Roger Blumenthal, director of the Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease, explains to HuffPost: "Angina can be a warning sign that a heart attack or another cardiac event could occur in the coming days." Doctors stress that angina doesn't necessarily mean intense pain — it can manifest as an unusual discomfort, which is why any new symptom of this kind should be discussed with a doctor.

Pain radiating to the neck, shoulder, arm, or jaw

Although a heart attack is commonly associated with pain in the left arm, the early signs can be more subtle. Discomfort may radiate towards the neck, shoulder, or arm, and some people experience a numbness that travels up to the jaw. Dr Blumenthal notes: "Sometimes angina presents as pain or pressure in the chest, but, especially in older individuals, other symptoms can also appear, including pain radiating to the neck, shoulder, or arm." Dr Abha Khandelwal, Associate Professor of Cardiovascular Medicine at Stanford Health Care, adds that the sensation can take the form of a numbness reaching as far as the jaw.

Breathlessness during everyday activities

Another warning sign is an unusually rapid onset of breathlessness, even during simple activities — household chores or gardening — that previously caused no difficulty. According to Dr Khandelwal, some people may also experience arm numbness or chest discomfort following more strenuous exertion.

Nausea, abdominal pain, and fatigue

These symptoms can easily be mistaken for digestive problems or simple exhaustion. Dr Nikhil Sikand, a cardiologist at Yale Medicine and professor at Yale School of Medicine, includes them among the possible warning signs and cautions: "Some patients may have mild symptoms or none at all."

Symptoms may intensify in the final week

The interval between the first signs and the onset of a heart attack varies from person to person. Dr Khandelwal notes that approximately two-thirds of her patients recall an episode of chest pain in the month before their heart attack. In the days immediately preceding the event, symptoms may become more frequent, prolonged, or intense: "In the day or week leading up to a heart attack, more symptoms can appear. They may become more frequent, last longer, or be more intense," the doctor said.

According to HuffPost, any rapid and severe worsening of these symptoms requires immediate medical attention. Even people with no prior cardiac history should speak to their doctor about any new symptom, however mild it may seem, as prompt intervention can make a significant difference to treatment outcomes.

Risk factors that can be kept under control

The American Heart Association lists among the factors that increase the risk of a heart attack: smoking, diabetes, high cholesterol, high blood pressure, and obesity. Dr Khandelwal emphasises: "If, before the disease develops, we manage to keep risk factors under control on a day-to-day basis, that is one of the most important things we can do for heart health."

Doctors also recommend maintaining regular contact with one's doctor, with periodic checks on these risk factors. Dr Blumenthal warns: "After a person has had a heart attack, the risk of a further cardiovascular event is higher in the following year. This is why lifestyle changes and appropriate medical treatment are so important."
