RELATIONSHIP BETWEEN. HYPERTENSION AND ANGINA PECTORIS. P.J. RICHARDSON. Senior Lecturer in Cardiology, King's College Hospital, Denmark . MOST efforts concerned with preventive cardiology have emphasized the importance of the coexistence of hypertension with noninfarction. The present study was undertaken to determine the pos- sible relationship between arterial pressure and exertional angina pectoris in hypertensive patients with.
When you climb stairs, exercise or walk, your heart demands more blood, but it's harder for the muscle to get enough blood when your arteries are narrowed. Besides physical activity, other factors such as emotional stress, cold temperatures, heavy meals and smoking also can narrow arteries and trigger angina.
If fatty deposits plaques in a blood vessel rupture or a blood clot forms, it can quickly block or reduce flow through a narrowed artery, suddenly and severely decreasing blood flow to your heart muscle. Unstable angina can also be caused by blood clots that block or partially block your heart's blood vessels.
Unstable angina worsens and isn't relieved by rest or your usual medications. If the blood flow doesn't improve, your heart is deprived of oxygen and a heart attack occurs.

Unstable angina is dangerous and requires emergency treatment. This type of angina is caused by a spasm in a coronary artery in which the artery temporarily narrows.
This narrowing reduces blood flow to your heart, causing chest pain. Emotional stress, smoking and use of the illegal drug cocaine may trigger this type of angina.

Risk factors The following risk factors increase your risk of coronary artery disease and angina: Chewing tobacco, smoking and long-term exposure to secondhand smoke damage the interior walls of arteries — including arteries to your heart — allowing deposits of cholesterol to collect and block blood flow. Diabetes is the inability of your body to produce enough or respond to insulin properly.
Insulin, a hormone secreted by your pancreas, allows your body to use glucose, which is a form of sugar from foods. Diabetes increases the risk of coronary artery disease, which leads to angina and heart attacks by speeding up atherosclerosis and increasing your cholesterol levels. Blood pressure is determined by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. Over time, high blood pressure damages arteries by accelerating hardening of the arteries.
High blood cholesterol or triglyceride levels.
Cholesterol is a major part of the deposits that can narrow arteries throughout your body, including those that supply your heart. A high level of the wrong kind of cholesterol, known as low-density lipoprotein LDL cholesterol the "bad" cholesterolincreases your risk of angina and heart attacks.
A high level of triglycerides, a type of blood fat related to your diet, also is undesirable.
Family history of heart disease. If a family member has coronary artery disease or has had a heart attack, you're at a greater risk of developing angina. Men older than 45 and women older than 55 have a greater risk than do younger adults.
An inactive lifestyle contributes to high cholesterol, high blood pressure, type 2 diabetes and obesity. High blood pressure can cause damage to the coronary arteries, leading to blockages in the arteries, and abnormal blood flow to the heart which causes angina or chest pain due to inadequate blood flow to the heart.
High blood pressure puts a lot of strain on the heart and the pressure the heart has to exert to pump blood against this high pressure requires more blood flow and oxygen. This causes angina when there is already coronary disease and blood flow cannot increase adequately in this situation. The feelings usually last only a few minutes. There is usually relief by sitting and resting for a few minutes or by taking nitroglycerin medication.
At times the activity which causes the pain can be predicted and avoided. For instance, some people find that angina only comes on if they are walking too fast, walking uphill or in cold weather.
There are several types of angina pectoris.
Angina - Symptoms and causes - Mayo Clinic
Stable angina pectoris means that the discomfort and limitation have not increased recently, such as over the previous 1 to 2 months. There may be chest pain, tightness or other discomfort on exertion or from other causes, but the severity and frequency of the episodes are the same.
The chest discomfort usually lasts less than five minutes and is relieved by resting or by nitroglycerin medication. In persons with stable angina, researchers usually find a narrowing of at least one of the coronary arteries.
