Few studies examined the effect of long-acting nitrates on renal function in chronic heart failure (CHF). Thus, we aimed to investigate the effect of long-acting nitrate on the expression of adrenoceptors (AR) and angiotensin II receptor (ATR) subtypes of the renal cortex, in rats with BACKGROUND
There is conflicting information about whether nitrate treatment aggravates long-term prognosis, so the present retrospective study was designed to determine the effects of long-term nitrate therapy on major adverse events after acute myocardial infarction (AMI) in the coronary
Since its introduction to the market in March 1997, sildenafil acetate (Viagra) has been prescribed to 1.7 million people. Sixteen men who were taking the drug have died, 7 of them during or soon after sexual activity. Most of these data have been derived from the media and not from the scientific
OBJECTIVE
To investigate the role of Tc-MIBI gated SPECT imaging following the administration of low-dose dobutamine plus nitrate (LDD+nitrate) in the assessment of left ventricular function and the perfusion of hibernate myocardial tissue.
METHODS
The study group comprised 29 patients diagnosed as
Intravenous nitroglycerin therapy during acute myocardial infarction has beneficial effects on infarct size, infarct complications, and mortality. Numerous dosage formulas for the continuous administration of nitrates are currently used, although several studies have demonstrated the rapid
The concentration of the nitric oxide (NO) metabolites nitrite (NO2-) and nitrate (NO3-) in the cerebrospinal fluid from patients with Alzheimer's disease (AD), vascular dementia of the Binswanger type (VDBT) or multiple small infarct type (MSID), and controls were determined using high performance
OBJECTIVE
To report the occurrence of acute myocardial infarction (MI) associated with the intake of oral sildenafil (Viagra) in a nitrate-free patient without previous history of coronary artery disease.
METHODS
A 50-year-old manual laborer was admitted to the hospital with acute inferoposterior
BACKGROUND
The aim of this study was to evaluate the ability of echocardiography, associated with nitroglycerin infusion, in the detection of myocardial viability in patients with recent infarction.
METHODS
Fourteen patients (11 male, 3 female, mean age 59 +/- 8 years) with first acute myocardial
Reports on the development of tolerance have modified the use of nitrates in the treatment of coronary heart disease. Dosage limitations and nitrate-free intervals are frequently recommended to solve this problem (4, 5). In the clinical setting of acute myocardial infarction continuous application
BACKGROUND
[corrected] Nitrates are widely used for the treatment of myocardial infarction (MI). The large megatrials (GISSI-3 and ISIS-4) did not in fact demonstrate a significant decrease in mortality in the nitrate-treated group. However, examination of the number of postinfarction angina
1. Seven randomized controlled trials of intravenous nitroglycerin in a total of about 850 patients have been reported. Overall, there were 51 deaths (12.5%) in the nitroglycerin group and 87 (20%) in the control group. This indicates a 48% reduction in the odds of death (P less than 0.001, 95%
BACKGROUND
Prolonged nitrate therapy during healing between 2 days and 6 weeks after anterior myocardial infarction has the potential for limiting further left ventricular remodeling (or changes in topography) and preserving function. Longterm therapy throughout healing over 6 weeks might be more
We performed coronary arteriography and gave intracoronary injection of nitrates within 8 hours after the onset of symptoms of acute myocardial infarction in eighteen patients. Improved distal filling or patency of the total occluded coronary artery after intracoronary injection of nitrates occurred
This study was performed to investigate the effects of continuous dosing of oral, transdermal (patch), and a combination of the two with nitrate treatments on cardiac events in patients with healed myocardial infarction. In total, 1,291 patients with healed myocardial infarction were assigned 2
This study was performed to investigate the effects of the chronic use of continuous, not eccentric, dosing of nitrates on cardiac events in patients with severe acute myocardial infarction. A total of 1,303 patients with healed myocardial infarction were divided into two groups: treatment with
