Aging is an inevitable progressive decline in physiological organ function that increases the chance of disease and death. The renin–angiotensin system (RAS) is involved in the regulation of ...

Although no information on prior therapy is given, it is reasonable to presume that a number of patients would have been on either a diuretic or an angiotensin-converting enzyme inhibitor.

However, the safety of permissive hypotension remains uncertain, particularly among patients who have suffered a traumatic brain injury. Vasopressors preferentially vasoconstrict blood vessels that ...

Our primary outcome is shock reversal (no further need or a reduced (≤10% of the maximum dose) vasopressor requirement for 3 hours) and time to shock reversal (number of hours elapsed from the start ...

Cardiovascular diseases are the number one cause of death worldwide and greatly impact quality of life and medical costs. Enormous effort has been made in research to obtain new tools for efficient ...

Urine flow 2. In 10 of 12 patients urine flow was significantly reduced during angiotensin infusion compared with metaraminol or levarterenol. 2. Shock due to sepsis 2. Nine patients. One survived, ...

Explore the latest innovations in cardiogenic shock treatment, including advances in mechanical circulatory support devices, ...

Peripheral arterial disease (PAD) is a common but under-recognized problem affecting older patients. Intermittent claudication is the most frequent symptom of PAD, although the diagnosis of PAD is ...

Fluid, electrolyte and mineral perturbations are prevalent features of tropical disease. Hemodynamic alterations, fever, nitrogen wasting, and changes in membrane transport and acid–base balance ...

Low blood pressure, also known as hypotension, occurs when blood flows through your blood vessels at pressures that are lower than normal. Low blood pressure is primarily a concern if it produces ...

However, medications like ACE inhibitors or angiotensin receptor blockers (ARBs) may need to be stopped 24 hours before surgery, particularly if you are undergoing heart surgery. This can reduce ...
