Angina is chest pain that originates in the heart muscle during physical activity. Angina is usually felt as: pressure, heaviness, tightening, squeezing, or aching across the chest, particularly behind the breastbone.

This pain often radiates to the neck, jaw, arms, back, or even the teeth. Patients may also suffer: indigestion, heartburn, weakness, sweating, nausea, cramping, and shortness of breath.

Conditions that exacerbate or provoke angina: medications, vasodilators, excessive thyroid replacement, vasoconstrictors, polycythemia which thickens the blood causing it to slow its flow through the heart muscle.

The following risk factors increase your risk of coronary artery disease and angina: tobacco use, diabetes, high blood pressure, high blood cholesterol or triglyceride levels, personal or family history of heart disease, older age (men older than 45 and women older than 55 have a greater risk than younger adults), lack of exercise, obesity, stress.
