what is the difference between primary and secondary pulmonary hypertension?
132703
Pulmonary hypertension was previously divided into primary and secondary categories; primary pulmonary hypertension described an idiopathic hypertensive vasculopathy exclusively affecting the pulmonary circulation, whereas secondary pulmonary hypertension was associated with a causal underlying disease process.

Complications of pulmonary hypertension include: Right-sided heart enlargement and heart failure (cor pulmonale). In cor pulmonale, your heart's right ventricle becomes enlarged and has to pump harder than usual to move blood through narrowed or blocked pulmonary arteries.

Essential hypertension is high blood pressure that doesn't have a known secondary cause. It's also referred to as primary hypertension.

Primary (essential) hypertension is diagnosed in the absence of an identifiable secondary cause. Approximately 90-95% of adults with hypertension have primary hypertension, whereas secondary hypertension accounts for around 5-10% of the cases.

Blood flow depends on vascular pressure. Total pressure drop from pulmonary artery to left atrium is about 10 mmHg while in the systemic circulation it is about 100 mmHg.

There Are Two Types of Circulation: Pulmonary Circulation and Systemic Circulation. Pulmonary circulation moves blood between the heart and the lungs. ... Systemic circulation moves blood between the heart and the rest of the body. It sends oxygenated blood out to cells and returns deoxygenated blood to the heart.

The main difference between secondary-progressive MS (SPMS) and primary-progressive MS (PPMS) centers on the presence or absence of relapses. SPMS develops in patients who initially had relapsing-remitting MS (RRMS) as a secondary phase of that disease course.

Having pulmonary arterial hypertension (PAH) means that you have high blood pressure in the arteries that go from your heart to your lungs . It's different from having regular high blood pressure. With PAH, the tiny arteries in your lungs become narrow or blocked.

It includes emphysema, pulmonary embolism, and other causes of pulmonary hypertension. High blood pressure in the pulmonary arteries increases the workload of the right ventricle. Over time, this causes the right ventricle to fail. This is blockage of the arteries that supply blood to your heart.

Pulmonary hypertension is high blood pressure in the blood vessels that supply the lungs (pulmonary arteries). It's a serious condition that can damage the right side of the heart. The walls of the pulmonary arteries become thick and stiff, and cannot expand as well to allow blood through.

Difference Between Primary Index and Secondary Index A primary index is an index on a set of fields that includes the unique primary key and is guaranteed not to contain duplicates. In contrast, a secondary index is an index that is not a primary index and may have duplicates.

Some cases of pulmonary hypertension are reversible, depending upon the cause. Some cases of pulmonary hypertension are reversible, depending upon the cause. Hyperthyroidism and Obstructive Sleep Apnea are two of those reversible causes.

Some common underlying causes of pulmonary hypertension include high blood pressure in the lungs' arteries due to some types of congenital heart disease, connective tissue disease, coronary artery disease, high blood pressure, liver disease (cirrhosis), blood clots to the lungs, and chronic lung diseases like emphysema ...

The pulmonary arteries carry low-oxygen blood from the right ventricle of the heart to the lungs. Systemic arteries transport oxygenated blood from the left ventricle of the heart to the rest of the body. Veins. The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart.

Due to loss of tremendous blood flow through the placenta, the systemic vascular resistance at birth doubles. As resistance rises, aortic pressure increases. Furthur in pressure in left ventricle, left atrium increases as well. Due to expansion of the lungs, the pulmonary vascular resistance greatly decreases.

Pulmonary hypertension (PH), is a complex and often misunderstood disease. The term PH means high blood pressure in the lungs. In “regular” hypertension (also known as high blood pressure or “systemic hypertension) the pressure in the arteries throughout the body is higher than it should be.
