Calcium is needed by all muscle cells, including those of the heart and muscles and surrounding arteries, in order for the cells to contract. CCBs inhibit the movement of calcium into muscle cells. The reduction in calcium reduces the force of the heart's muscular pumping action (cardiac contraction) and thereby reduces blood pressure. These medications also relax the muscle cells surrounding the arteries to further reduce blood pressure. Three major types of calcium channel blockers are available. One type is the dihydropyridines, which do not slow the heart rate or cause other abnormal heart rates or rhythms (cardiac arrhythmias). They are commonly used for treating high blood pressure and are very effective in reducing blood pressure in African Americans.
Controlling your blood pressure is a lifelong task. Blood pressure is only one of a number of factors that increase your risk of heart attack, stroke, and death. High cholesterol and diabetes are other risk factors. Lifestyle changes—such as weight loss, a healthy diet, and physical activity—can affect all three risk factors, but many people will also need medications.
Yes, exercise is an excellent way to help lower your blood pressure. Of course, before you start any exercise program, be sure to talk to your doctor. With your doctor’s guidance, exercise can be a healthy way to help get your blood pressure under control. Exercise strengthens your heart and makes it work more efficiently. This means it won’t have to pump as hard, which leads to lower blood pressure.
However, sometimes a high reading can occur temporarily and then your numbers will return to normal. If your blood pressure measures at this level, your doctor will likely take a second reading after a few minutes have passed. A second high reading indicates that you’ll need treatment either as soon as possible or immediately depending on whether or not you have any of the symptoms described above.
Blood pressure is the force of blood pushing against the walls of arteries. When the doctor measures your blood pressure, the results are given in two numbers. The first number, called systolic blood pressure, is the pressure caused by your heart contracting and pushing out blood. The second number, called diastolic blood pressure, is the pressure when your heart relaxes and fills with blood. Your blood pressure reading is usually given as the systolic blood pressure number over the diastolic blood pressure number, such as 138/72. Normal blood pressure for adults is defined as a systolic pressure of less than 120 and a diastolic pressure of less than 80. This is stated as 120/80.
Many leafy greens, including everything arugula and kale to spinach and collard greens, contain potassium and magnesium which are key minerals to control blood pressure, according to Harvard Medical School. These nutrients are an important part of the DASH diet (Dietary Approaches to Stop Hypertension, or high blood pressure), which suggests a variety of foods that lower blood pressure. A potassium-rich diet helps the body become more efficient at flushing out excess sodium, which can raise blood pressure, and magnesium helps promote healthy blood flow, according to nutritionist Joy Bauer.
4. Cut down on processed food. Just about all processed foods contain huge amounts of fructose, particularly fruit drinks or any fruit-flavored products. Fructose is hidden all over the supermarket, even in the most unlikely places: processed meats, breads, pasta sauces and dressings. Fast food chains love fructose. The only thing they love more is vegetable oil.
