Heart attacks have become the leading cause of death worldwide, often linked to “stressful lifestyles and unhealthy diets.” Protecting your heart requires healthier habits, including better nutrition and stress reduction.

Warning signs of heart failure can appear up to a month before a heart attack. Shortness of breath is one of the earliest symptoms. When “the lungs do not receive enough oxygen, the heart struggles to pump blood effectively.” Anyone experiencing breathing difficulties should seek medical advice immediately.

Some people report cold or flu-like symptoms beforehand. Chest pressure or discomfort is especially serious, as it “is a clear sign that a heart attack may occur soon.” Ignoring chest pain can be life-threatening.

Weakness, fatigue, dizziness, and cold sweats may also signal reduced blood flow from narrowed arteries. As the article notes, “when muscles do not receive the necessary nutrients and oxygen, they become weak.”

Persistent tiredness or drowsiness, even with enough rest, can indicate poor circulation and loss of blood flow to the heart. Recognizing these symptoms early and seeking treatment can “significantly reduce the risk of experiencing a heart attack.”
