Is a high diastolic pressure a sure sign of heart attack?

A high diastolic pressure is not a definitive sign of a heart attack. While elevated diastolic pressure can indicate potential cardiovascular issues, it is not specific to heart attacks and may arise from various factors such as stress, obesity, or underlying health conditions. Heart attacks typically involve a combination of symptoms, including chest pain, shortness of breath, and other risk factors rather than relying solely on blood pressure readings. It's essential to consult a healthcare professional for a comprehensive evaluation if there are concerns about heart health.
