BACKGROUND: Papaverine remains a popular agent to treat intraoperative microsurgical vasospasm. However, the recent shortage has forced surgeons to trial antispasmodic agents unproven in microsurgery, but commonly used in other areas. During this shortage we have trialed topical nitroglycerin to break intraoperative vasospasm. This study aims to analyze the outcomes of this medication on flap complications compared with papaverine. METHODS: All consecutive free flaps performed for breast reconstruction at a single institution were reviewed...

BACKGROUND: Accurate noninvasive diagnostic tools for evaluating left ventricular (LV) diastolic dysfunction (LVDD) are limited in preserved LV ejection fraction. We previously proposed the relationship of normalized rate of change in LV torsion shear angle (φ') to corresponding rate of change in LV volume (V') during early diastole (represented as -dφ'/dV') as a measure of LV diastolic function. We prospectively evaluated diagnostic accuracy of -dφ'/dV' in respect to invasive LV parameters...

OBJECTIVE: Little is known about treatments provided by advanced life support (ALS) ambulance teams to patients with acute heart failure (AHF) during the prehospital phase, and their influence on short-term outcome. We evaluated the effect of prehospital care in consecutive patients diagnosed with AHF in Spanish emergency departments (EDs). METHODS: We selected patients from the EAHFE registry arriving at the ED by ALS ambulances with available follow-up data. We recorded specific prehospital ALS treatments (supplemental oxygen, diuretics, nitroglycerin, non-invasive ventilation) and patients were grouped according to whether they received low- (LIPHT; 0/1 treatments) or high-intensity prehospital therapy (HIPHT; > 1 treatment) for AHF...

Studies have linked exposure to ultrafine particulate matter (PM) and adverse cardiovascular events. PM-induced oxidative stress is believed to be a key mechanism underlying observed adverse vascular effects. Advanced age is one factor known to decrease antioxidant defenses and confer susceptibility to the detrimental vascular effects seen following PM exposure. The present study was designed to investigate the vasomotor responses following ultrafine PM exposure in wild type (WT) and superoxide dismutase 2-deficient (SOD2+/-) mice that possess decreased antioxidant defense...

BACKGROUND AND PURPOSE: G protein-coupled receptors exist in multiple conformations that can engage distinct signaling mechanisms which in turn may lead to diverse behavioral outputs. In rodent models, activation of the delta opioid receptor (δ-receptor) has been shown to elicit antihyperalgesia, antidepressant-like effects, and convulsions. We recently showed that these δ-receptor-mediated behaviors are differentially regulated by the GTPase-activating protein regulator of G protein signaling 4 (RGS4), which facilitates termination of G protein signaling...

Nitroglycerin is commonly used as an antispasmodic for treating spasm of coronary artery bypass grafts. This study investigated whether the presence of renal failure affects reactivity to nitroglycerin in internal thoracic arteries obtained from patients undergoing coronary bypass surgery. The patients were divided into three groups according to estimated glomerular filtration rate (eGFR, mL/min/1.73 m2): without renal failure (60 ≤ eGFR, n = 13), with moderate renal failure (30 ≤ eGFR < 60, n = 10), and with severe renal failure (eGFR < 30, n = 10)...

The benefits of nitroglycerin are numerous, from ensuring accurate interpretation of diagnostic angiograms to treatment of coronary spasm and support of PCIs in simple or complex lesion types. The founders of the field were convinced that no coronary arteriography should be considered complete unless a vasodilator is used at some point during the study. This recommendation is valid. The guidelines should change to include administration of intracoronary nitroglycerin.
