Primary pulmonary hypertension
Primary pulmonary hypertension – also known as idiopathic pulmonary hypertension – it just means that no underlying cause can be identified for the condition. Primary pulmonary hypertension is rare (incidence of 1 or 2 people per million), and is more likely to occur in women than in men. It is now believed that many cases of primary pulmonary hypertension associated with a genetic defect.
The treatment of pulmonary hypertension is strongly based on treating the underlying cause, so doctors should not be in a diagnosis of primary pulmonary hypertension until all forms of secondary pulmonary hypertension have been carefully excluded.
Secondary pulmonary hypertension

The term “pulmonary hypertension” secondary “simply means that pulmonary hypertension was caused by an underlying medical condition. If you have pulmonary hypertension, it is essential to leave no stone unturned to try to identify the underlying cause.
Medical conditions that can cause pulmonary hypertension include heart disorders, lung disorders, connective tissue diseases, drugs, and a handful of other medical conditions.

Cardiac conditions that can cause pulmonary hypertension include:
Cardiomyopathy
Diastolic dysfunction
Mitral stenosis or mitral regurgitation
Aortic stenosis or aortic insufficiency
Constrictive Pericarditis
Congenital Heart Disease
Two forms of congenital heart disease in particular may go unnoticed until you reach adulthood and begin to show signs of pulmonary hypertension. This is the atrial septal defect and ventricular septal defect.

ulmonary disorders that can cause pulmonary hypertension include:
Chronic obstructive pulmonary disease (COPD)
Interstitial lung disease
Sleep Apnea
Chronic pulmonary embolism
Connective tissue diseases that can cause pulmonary hypertension include:
Systemic sclerosis or scleroderma

Lupus
Rheumatoid Arthritis
Drugs that can cause pulmonary hypertension include:
Suppressant drugs fenfluramine and dexfenfluramine diethylpropion
Amphetamine, methamphetamine and cocaine
Chemotherapy drugs
Other medical conditions that can cause pulmonary hypertension include:
HIV / AIDS
Schistosomiasis
Various forms of liver disease
Chronic hemolytic anemia
Summary
There are many causes of pulmonary hypertension, which can make identification of the underlying cause difficult. However, because the treatment is mainly directed at the underlying cause, if you have pulmonary hypertension is extremely important to take all necessary measures to find an underlying cause of your condition.

Hypertension is the increase in blood pressure chronically. It’s a disease no symptoms for a long time and, if untreated, can trigger severe complications such as myocardial infarction, cerebral hemorrhage or thrombosis, which can be avoided if handled properly. The first consequences of hypertension are suffered arteries that harden as they bear high blood pressure continuously, thicken and may be impeded the passage of blood through it. This is known as atherosclerosis.

Causes

The mechanism of hypertension most common, called “essential hypertension”, “primary” or “idiopathic”. In essential hypertension have not yet described the specific causes, but has been linked with a number of factors that are usually present in most people who suffer. Should be separated from those related to heredity, sex, age and race and rarely modifiable, those that could be changed by varying habits, environment, and morals of individuals, such as obesity, sensitivity sodium, excessive alcohol consumption, oral contraceptive use and a very sedentary lifestyle.

• Inheritance: when transmitted from parent to child inherits a tendency or predisposition to develop high levels of blood pressure. Exact mechanism is unknown, but past experience shows that when a person has a parent (or both) with hypertension, the chances of developing hypertension are twice those of other people with both parents without a history of hypertension.

• Sex: Men are more predisposed to high blood pressure than women until they reach the age of menopause. From this stage the frequency in both sexes is equal. This is because nature has endowed woman with a protective hormones while you are of childbearing age, estrogen, and therefore have a lower risk of cardiovascular disease. However, in younger women there is a special risk when taking birth control pills.

• Age and Race: Age is another factor, unfortunately coded, which will influence blood pressure numbers, so that both systolic and diastolic pressures, or maximum or minimum increase with age and is logically a greater number of hypertensive patients with increasing age. As for the race, people of African descent are twice as likely to develop hypertension than whites, also have a worse prognosis.

• Overweight: Overweight individuals are more likely to have higher blood pressure than normal-weight individual. As weight increases blood pressure rises and this is much more evident in those under age 40 and women. The frequency of hypertension among the obese, regardless of age, is two to three times higher than individuals of normal weight. It is unclear whether obesity is itself the cause of hypertension, or if there is an associated factor that increases pressure in overweight, although recent research suggests that obesity is associated with another series of alterations that be in part responsible for increased blood pressure. It is also true that the reduction in weight makes these alterations disappear.
