It's the same with angina, except that it's your heart that's not getting enough oxygen. Angina may be a warning sign that you're at risk for heart disease or a heart attack. Medicine may be prescribed for your angina. Some medications help open up the blood vessels around your heart, while others help reduce the work your heart has to do. This lets more blood and oxygen flow to your heart and may lessen the pain of angina attacks.
Blood pressure measures the force the blood causes as it flows through the blood vessels.
When the blood vessels narrow, the heart has to work harder to push the blood through the vessels, thus raising the blood pressure. People with high blood pressure often don't know they have it until their blood pressure is measured. Therefore, it's important to get regular medical check-ups, no matter how healthy you think you are or how good you feel. High blood pressure may have serious consequences. You can control high blood pressure.
