The time it takes for blood pressure to rise and return to normal after anger ranges from minutes to hours, depending on the patient’s ability to control his or her emotions. Emotional excitement causes a stress response in the body, resulting in the release of adrenaline, among other things, which can cause a rise in blood pressure. In the case of minor mood swings, the blood pressure will drop to normal within a few minutes of rest. If the patient has something seriously irritating, and the mood swings are severe for a longer period of time, the blood pressure increase is possible, up to several hours of continuous non-decrease. Patients who are experiencing a major event with no better way to control their emotions, and in severe cases require medication to keep their blood pressure under control, will experience stress-related symptoms. Commonly used antihypertensive drugs include captopril, irbesartan, nifedipine, hydrochlorothiazide, spironolactone, metoprolol, and bisoprolol. Medications should be used under the supervision of a physician, and patients with hypertension should seek prompt medical attention.
