Causes and Treatment of Hypertension

Hypertension can be classified either essential (primary) or secondary. Essential hypertension indicates that no specific medical cause can be found to explain a patient’s condition. Secondary hypertension indicates that the high blood pressure is a result of (i.e., secondary to) another condition, such as kidney disease or tumours (pheochromocytoma and paraganglioma). Persistent hypertension is one of the risk factors for strokes, heart attacks, heart failure and arterial aneurysm, and is a leading cause of chronic renal failure.

Cause and Pathogenesis

The cause of primary (essential) hypertension is not known. It is thought to be due to multiple risk factors. Known risk factors include a familial history of the disease, race, obesity, tobacco smoking, stress, and a high-fat or high-sodium diet in genetically susceptible individuals. Extremely nervous and highly emotional people also tend to develop hypertension more readily. Secondary hypertension is related to an underlying disease process such as renal parenchymal disorders , renal artery disease, endocrine and metabolic disorders, central nervous system disorders, and narrowing of the aorta (coarctation).

Causes Pulmonary Hypertension: Pulmonary hypertension results from constriction, or tightening, of the blood vessels that supply blood to the lungs. Consequently, it becomes difficult for blood to pass through the lungs, making it harder for the heart to pump blood forward. This stress on the heart leads to enlargement of the heart and eventually fluid can build up in the liver and tissues, such as the in the legs. Affected patients can sometimes notice increasing shortness of breath and dizziness.

What are the symptoms of Hypertension?

If you have hypertension, chances are that you may not have any symptoms at all. Hypertension is often called the “silent killer” because most people who have it do not feel sick, but if left uncontrolled, it can lead to a heart attack or kidney disease. This is why it is so important to treat hypertension even if you feel fine. Many people can keep their hypertension under control by making some changes in their daily activities, such as increasing exercise and eating a healthier diet. Other people may need to take medicine in addition to diet and/or exercise.

Hypertension Treatment

Hypertension, or high blood pressure, is dangerous because it can lead to strokes, heart attacks, heart failure, or kidney disease. The goal of hypertension treatment is to lower high blood pressure and protect important organs, like the brain, heart, and kidneys from damage. Treatment for hypertension has been associated with reductions in stroke (reduced an average of 35%-40%), heart attack (20%-25%), and heart failure (more than 50%), according to research.

Treating high blood pressure can help prevent serious — even life-threatening — complications. Your doctor also may suggest steps to control conditions that can contribute to high blood pressure, such as diabetes and high cholesterol.

The treatment for secondary pulmonary hypertension usually begins with treating the underlying cause. For instance, if a blood clot, or pulmonary embolism, is causing the hypertension, the clot may need to be surgically removed.

For individuals with hypertension, lifestyle modifications as mentioned above are important but many times, medications will also be needed to adequately manage blood pressure. Many types of drugs are used to lower blood pressure.
