Identifying the initial cautionary signs of a heart attack holds the potential to preserve lives. Nonetheless, the symptoms of a heart attack exhibit variability. Certain individuals experience mild indications, while others encounter severe manifestations, and a subset may even remain asymptomatic.

A cardiac event transpires when a coronary artery, responsible for transporting blood and oxygen to the heart, becomes obstructed. Over time, deposits rich in fatty substances and cholesterol accumulate, giving rise to plaques within the heart's arteries. In the event of plaque rupture, a blood clot can form, leading to arterial blockage and consequent heart attack. The absence of adequate blood flow during a heart attack results in the demise of tissue within the cardiac muscle.

Dr. Nnenna Ezeigwe, a former Director and National Coordinator for Non-Communicable Diseases at the Federal Ministry of Health, highlights that a staggering four out of five fatalities resulting from cardiovascular diseases stem from heart attacks and strokes.

Listed below are several preliminary indications of a heart attack:

Chest discomfort: As indicated by the National Health Service, a heart attack may present with sensations of pressure, heaviness, tightness, or constriction in the chest. This sensation is typically centered on the left side of the chest or in its middle, lasting for more than a few minutes. It might recede temporarily before resurfacing.

Breathlessness: Often associated with a silent heart attack, experiencing shortness of breath can occur with or without accompanying chest pain. Feelings of dizziness or lightheadedness may also be present.

Perspiration: Experiencing heightened perspiration beyond your usual levels, particularly when not engaged in physical activity, could serve as an early cautionary indicator of potential heart issues. An article published on the online health platform Healthline suggests that when the heart has to work harder to pump blood through blocked arteries, the body increases sweating as a mechanism to regulate body temperature during this added strain. Should you encounter cold sweats or damp skin, seeking medical advice is advisable.

"Night sweats, a prevalent symptom among women facing heart-related challenges, might be misconstrued as a result of menopause. However, if you awaken to soaked sheets or insomnia due to excessive perspiration, it could signify a potential heart attack, especially in women," the article emphasizes.

Discomfort: Sensations of pain or discomfort that radiate to the shoulder, arm, back, neck, jaw, teeth, or occasionally the upper abdomen also warrant attention as possible indicators of a heart attack.

A Professor of Cardiology at the BHF Centre of Research Excellence, Prof Newby was quoted by The Daily Express as saying, “If your pain is going down the arm, especially the left arm, or into the neck that makes it more likely to be heart-related than indigestion.

"If the discomfort persists, or if you have a history of heart disease and have used your glyceryl trinitrate spray multiple times without evident relief, it is imperative to seek immediate medical assistance."

Experiencing queasiness: Professor Newby suggested that if an individual undergoes severe chest pain even during periods of inactivity and simultaneously feels nauseous, this could indicate a potential heart attack. While not every instance of nausea signifies a heart attack, the presence of chest pain coupled with nausea should prompt heightened vigilance.

Medical experts emphasize that certain heart attacks can manifest suddenly. However, numerous individuals exhibit warning signs and symptoms hours, days, or even weeks before an episode. They highlight that persistent chest pain or pressure that persists despite rest might serve as an early indicator of an impending heart attack.
