Background: ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI ) are common types of acute coronary syndrome which are associated with the risk factors of age, obesity, hypertension, and diabetes. Objective: The present study aimed to examine the effects of age on the risk factors and clinical sym...

mild (140 to 159/90 to 99 mmhg) or moderate (160 to 179/100 to 109 mmhg) chronic arterial hypertension does not appear to cause headache. whether moderate hypertension predisposes patients to headache at all remains controversial, but there is little evidence that it does. ambulatory blood pressure monitoring in patients with mild and moderate hypertension has shown no convincing relationship b...

introduction: we evaluated the incidence and clinical outcome of patients with hypertensive acute ischemic stroke (ais) admitted to a tertiary care center in central india. in addition, we examined the status of stroke biomarkers namely neuron-specific enolase (nse), glial specific protein (s-100ββ), and inter-α-trypsin inhibitor heavy chain 4(itih4) in the serum of patients suffering from ais ...

hypertension in newborn infants, particularly those requiring intensive care, is becoming increasingly recognized, with prevalence of 0.2-3%. recent studies have established normative tables for blood pressure (bp) in both term and pre-term infants based on the gestational age, postnatal age, gender, weight and height, identifying the neonates at increased risk for early-onset cardiovascular di...

Background: The effects of vitamin D in skeletal system, biological metabolism and immune system function are well shown. Cholecalciferol (vitamin D3) and ergocalciferol (vitamin D2) are two major types of vitamin D. Vitamin D deficiency is widely in human population and vitamin D intoxication is very rare. Case Description: The patient is 37-years old bodybuilder man who referred to emergency...

background: nitric oxide synthase (nos) activity is increased during hypertension and cerebral ischemia. nos inactivation reduces stroke-induced cerebral injuries, but little is known about its role in blood-brain barrier (bbb) disruption and cerebral edema formation during stroke in acute hypertension. here, we investigated the role of nos inhibition in progression of edema formation and bbb d...

Objective: Angiotensin II (Ang II), the main product of renin-angiotensin system (RAS) has a well-known role in cardiovascular regulation. Over-production of Ang II is one of the important underlying mechanisms of hypertension. In this study, the effect of crocin on cardiovascular responses in rats with acute hypertension induced by Ang II was evaluated. Materials and methods: Rats were divided...

Background: Nitric oxide synthase (NOS) activity is increased during hypertension and cerebral ischemia. NOS inactivation reduces stroke-induced cerebral injuries, but little is known about its role in blood-brain barrier (BBB) disruption and cerebral edema formation during stroke in acute hypertension. Here, we investigated the role of NOS inhibition in progression of edema formation and BBB d...

The expression 'hypertensive urgencies' includes many diseases. The unifying features of these diseases are a high level of arterial pressure and acute distress of one or more organs. The aim of the review was to define the idea of the 'acute hypertension' as a new concept, different from 'chronic hypertension'. Acute hypertension might be related to 'organ damage' because it is the cause, the ...

Pulmonary artery pressure elevation complicates the course of many complex disorders treated in a noncardiac intensive care unit. Acute pulmonary hypertension, however, remains underdiagnosed and its treatment frequently begins only after serious complications have developed. Significant pathophysiologic differences between acute and chronic pulmonary hypertension make current classification an...
