True or false right heart failure causes a back up of blood into pulmonary circulation?
false RHF causes backup into the systemic circulation
What is pulmonary infarction?
A Pulmonary Infarction is the death of a small area of lung resulting from pulmonary embolism. It occurs in a small, dead-end pulmonary artery and often causes pain in the back or chest.PI is an an infrequent consequence of Pulmonary Edema(< 10% of cases). It is sometimes due to thrombosis in situ of the pulmonary arteries as might occur in congenital heart disease associated with severe pulmonary hypertension or in hematologic disorders (eg, sickle cell anemia).
What causes an enlarged left atrium?
There may be many causes of an enlarged left atrium to include mitral stenosis, mitral regurgitation and left ventricle failure. Other causes are ventricular septal defect and patent ductus arteriosus.
What are the three major causes of cardiovascular disease?
The American Heart Association (AHA) uses the term cardiovascular disease (CVD) to describe various diseases that affect the heart and circulatory system. These diseases include coronary artery (heart) disease, hypertension, congestive heart failure, congenital cardiovascular defects, and cerebro-vascular disease.
Respiratory causes of low blood pH?
renal failure
What causes of left sided fine basal inspiratory crepitation?
One possible cause is pulmonary congestion from left ventricular failure. See links for more.
Why does Pulmonary Arterial Hypertension develop?
Some common causes are: Sleep apnea Emphysema Some people develop pulmonary hypertension without there being an obvious cause. This is called Idiopathic Pulmonary Hypertension.
What occurs in the heart in response to hypertension?
Hypertension causes the left ventricular wall to thicken. This is followed by a dilatation of the left ventricle and a reduction in the amount of blood pumped from the heart.
Why lung crepitation occur in MI?
MI causes heart failure. . in heart failure , the increase of left ventricular pressure with failure of blood to pump into aorta occurs. . leads to back flow of blood into lungs through pulmonary veins. . this results to interstitial pulmonary odema and opening of alveoli , during inspiration is not normal, with external pressure to its normal opening. . this takes place with a sound , called fine crepitations
What causes frothy white lung secretions?
Pulmonary edema, Congestive heart failure,
How mitral stenosis complicated by pulmonary fibrosis?
Because pulmonary fibrosis causes hypoxia which further aggravates pulmonary edema & hence pulmonary hypertension which further increases the back pressure thus ultimately leading to more complicated mitral stenosis.
What is idiopathic pulmonary arterial hypertension?
Primary pulmonary hypertension is generally classified as a disease of the lung, related to high blood-pressure. Essentially, the increased pressure causes some pulmonary arteries and veins to work at drastically different rates than others, creating an imbalance that can cause fatigue, shortness of breath, fainting, and a persistent cough.
What causes Chronic dyspnea?
Chronic dyspnea can be caused by asthma, chronic obstructive pulmonary disease (COPD), bronchitis, emphysema, inflammation of the lungs, pulmonary hypertension, tumors, or disorders of the vocal cords
What causes pha?
PHA is caused when the blood vessels in the lungs receiving the low oxygen blood from the heart. This is also called Pulmonary Hypertension.
What does excessive ingestion of ethanol over a long period causes?
That causes the cirrhosis of the liver. You get the signs of liver failure and portal hypertension at the same time.

false RHF causes backup into the systemic circulation
