Mean arterial pressure (MAP) has traditionally been derived from systolic and diastolic pressures, weighted 1/3 systolic and 2/3 diastolic. No correction is made for the increasing time dominance of systole with increasing heart rates. In a previous study, we developed a new and more accurate heart rate-corrected MAP formula from central aorta pressure(More)
To evaluate the prevalence of clinically significant renal artery stenosis (RAS) in patients referred for coronary angiography, we analyzed data on 2,439 consecutive patients. Patients underwent selective renal angiography in conjunction with coronary angiography if refractory hypertension (blood pressure > 140/90 on two drugs) or flash pulmonary edema was(More)
Angiotensin-converting enzyme inhibitors (ACEIs) are contraindicated in patients with bilateral renal artery stenosis due to risk of azotemia resulting from preferential efferent arteriolar vasodilation in the renal glomerulus due to inhibition of angiotensin II. Patients with renal artery stenosis who can derive survival benefit from ACE inhibition,(More)
Acute meningococcemia is a clinical syndrome resulting from Neisseria meningitides infection. The clinical presentation is varied, but when associated with myocardial dysfunction, it carries a poor prognosis. We report a case of meningococcal myocarditis causing severe left ventricular systolic dysfunction that improved over a 4-day period after appropriate(More)
