In 11 patients with hypertension associated with acute myocardial infarction intravenous phentolamine decreased the elevated left ventricular filling pressure. Cardiac index increased with a small decrease in arterial pressure, and therefore the same or increased stroke work was achieved at a lower filling pressure. In patients with acute hypertension myocardial oxygen demand was decreased and ...

The follow-up of patients with acute pulmonary embolism is an essential component their comprehensive care. This manuscript will discuss the critical components involved in outpatient embolism, including development post hospitalization clinics, assessment functional capacity and residual right ventricular function, anticoagulation, recurrence risk venous thromboembolism, retrieval inferior ven...

conclusions it seems that in people with type 2 diabetes, acute aerobic exercise can decrease the plasma levels of glucose, possibly through increasing orexin a. in addition, negative energy balance is necessary to decrease the levels of insulin and insulin resistance during acute aerobic exercise. results the analysis of findings in p ≤ 0.05 indicated that acute aerobic exercise caused a signi...

CHRONIC HYPERTENSION is a major health problem worldwide affecting 25% of the population. Because it is a key risk factor for cerebrovascular disease and stroke and a leading cause of cognitive decline, chronic hypertension has an enormous negative impact on the brain. Episodes of acute hypertension (hypertension emergencies) present an additional array of cerebrovascular and neurological probl...

Acute hypertension rapidly inhibits proximal tubule (PT) Na,K-ATPase activity and sodium reabsorption 30 to 40%, increasing sodium and volume delivery to the thick ascending loop of Henle (TALH) and macula densa, providing the error signal for tubuloglomerular feedback. The hypothesis was tested in rats that an acute increase in sodium and volume delivery to the TALH would acutely increase oute...

Topics include antiplatelet drugs for acute coronary syndrome, renal denervation for hypertension, contrast-induced nephropathy, "e-cigarettes," and resistant hypertension.
