The captopril challenge test (CCT) is a non-invasive medical test that measures the change in renin plasma-levels in response to administration of captopril, an angiotensin converting enzyme inhibitor. It is used to assist in the diagnosis of renal artery stenosis.
The Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR) is a disease specific patient-reported outcome measure which assesses quality of life of patients with pulmonary hypertension (PH). [1] It was the first pulmonary hypertension specific questionnaire for assessing patient reported symptoms, quality of life and functioning.
Pulmonary hypertension (PH or PHTN) is a condition of increased blood pressure in the arteries of the lungs. [7] Symptoms include shortness of breath, fainting, tiredness, chest pain, swelling of the legs, and a fast heartbeat. [7] [1] The condition may make it difficult to exercise. [7] Onset is typically gradual. [8]
Guidelines for treating resistant hypertension have been published in the UK [45] and US. [46] It has been proposed that a proportion of resistant hypertension may be the result of chronic high activity of the autonomic nervous system, known as "neurogenic hypertension". [47] Low adherence to treatment is an important cause of resistant ...
A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.
A separate study with a mixture of 4-slice and 16-slice scanners reported a sensitivity of 83% and a specificity of 96%, which means that it is a good test for ruling out a pulmonary embolism if it is not seen on imaging and that it is very good at confirming a pulmonary embolism is present if it is seen.
A hypertensive emergency is very high blood pressure with potentially life-threatening symptoms and signs of acute damage to one or more organ systems (especially brain, eyes, heart, aorta, or kidneys). It is different from a hypertensive urgency by this additional evidence for impending irreversible hypertension-mediated organ damage (HMOD).
Two primary stress tests utilized are a treadmill test using ECG/electrophysiology metrics and nuclear testing, each have unique sensitivity and specificity values. The treadmill test, employing the modified Bruce protocol , [ 20 ] demonstrates a sensitivity range of around 73-90% and a specificity range of around 50-74%.
