Chest pain due to HPN. similar to the changes that occur when a blood pressure cuff around the arm is inflated. The pressure within the cuff is transmitted to the arm itself, and directly to the brachial artery within the arm.
similar to the changes that occur when a blood pressure cuff around the arm is inflated.
In the case of the heart, when the blood pressure is elevated, that pressure is transmitted back to the cavity of the left ventricle. The increase in pressure is transferred to the heart muscle itself. When the transmitted pressure within the heart wall is great enough, it will cause the small coronary arteries within the muscle, that are branches and smaller in diameter than the surface coronary arteries, to collapse. Therefore, blood flow within the muscle will be reduced or cease altogether, and chest pain will result.
