INTRODUCTION Skin has a large dynamic capacity for alterations in blood flow, and is therefore often used for recruitment of blood during states of hypoperfusion such as during burn shock resuscitation. However, little is known about the blood flow and metabolic consequences seen in the dermis secondary to the use vasoactive drugs (i.e. noradrenaline) for circulatory support. The aims of this s...

Arterial tone in muscular conduit arteries may influence pressure wave reflection through changes in diameter and pulse wave velocity. We examined the relative specificity of vasodilator drugs for radial artery and forearm resistance vessels during intrabrachial arterial infusion. The nitric oxide (NO) donors, nitroglycerine and nitroprusside, and brain natriuretic peptide were compared with th...

Native coronary artery spasm after coronary artery bypass grafting (CABG) is scarce. It frequently causes disastrous circulatory collapse. We report a 72-yr-old male, who experienced native coronary artery spasm and grafted artery spasm following CABG, which was successfully treated with coronary angiography and intracoronary injection of nitroglycerine.

Coronary artery spasm after coronary artery bypass grafting (CABG) is a rarephenomenon often resulting in heart failure. We report a case of 56-yearr-old male, who had coronary artery spasm after CABG, which was successfully treated with intracoronary injection of nitroglycerine and heparin.

OBJECTIVE Cardiovascular diseases are associated with impaired flow-mediated vasodilation (FMD) and increase in carotid intima-media thickness (IMT). Both FMD and IMT are independent predictors for cardiovascular outcomes. When measuring FMD and nitroglycerine-induced vasodilation in the brachial artery, IMT can also be simultaneously assessed in the same brachial artery. The purpose of this st...

A 28 year old male, known case of nephrotic syndrome since 12 years, hypertensive presented with acute myocardial infarction (AMI) and accelerated hypertension. Coronary angiography revealed 100% thrombotic occlusion of mid left anterior descending artery, treated with thrombus aspiration and intracoronary tirofiban and nitroglycerine. He was stabilized within 24 hours. The pathogenesis of AMI ...

Acute mediastinitis is an uncommon and potentially devastating infection. Generally, mediastinitis occurs as a postoperative infection following median sternotomy. We describe a case of acute mediastinitis in a patient with ischaemic heart disease, secondary to the spread of cutaneous infection of the chest wall in the application site of transdermal nitroglycerine patches.

BACKGROUND Since it has been demonstrated that soy diet can improve endothelial function, in the present study we evaluated the effect of dietary substitution of 25 g of animal proteins with soy proteins on endothelial dysfunction in renal transplant patients. METHODS In 20 renal transplant patients (55 +/- 11 years, serum creatinine 1.7 +/- 0.6 mg/dl), brachial artery flow mediated dilation ...
