The association of alpha-1 antitrypsin deficiency (PiZ phenotype) with systemic nodular panniculitis has been well documented. Despite reports of cases of systemic nodular panniculitis associated with other alpha-1 antitrypsin deficiency phenotypes, it is still not known if this association is fortuitous rather than causal. We report a case of systemic(More)
A study was undertaken to determine whether parent-child blood pressure (BP) resemblances reflect parent-child similarities in body build. Those studied were 889 children, 5-18 years old, their parents and relatives because of recognized correlations between body build and BP in individuals, along with familial clustering of these variables. To maximize the(More)
Mean hourly parameters obtained from all beats (long series) were compared with those obtained from a sample of 512 beats extracted each hour (short series) in nine presumably normal subjects. For both the short and long series, the spectral components, very low frequency, (VLF), low frequency (LF), and high frequency (HF), and time-domain indices (such as(More)
The authors describe a case of a middle-age male with recurrent syncope, in whom the tilt test was useful in the diagnosis and therapeutic evaluation. Malignant criteria of vasovagal syncope were established and the beta blocking worsening effect was documented, in spite of the general agreement of the first choice drug.
BACKGROUND Pulmonary hypertension is associated with a worse prognosis after cardiac transplantation. The pulmonary hypertension reversibility test with sodium nitroprusside (SNP) is associated with a high rate of systemic arterial hypotension, ventricular dysfunction of the transplanted graft and high rates of disqualification from transplantation.

OBJECTIVES Characterize power spectrum pattern of the heart rate variability and assessment of the relative contributions of sympathetic and parasympathetic cardiac nervous system control in athletes. STUDY DESIGN Prospective study of athletes and sedentary healthy control group sex and age matched. SUBJECT AND METHODS 8 athletes, 3 female and 5 male,(More)
OBJECTIVES Characterize power spectrum pattern of heart rate variability (HRV) and assessment of relative cardiac nervous system in patients with acute myocardial interaction of sympathetic and parasympathetic infarction. We also compared the spectral power with some known prognostic risk variables. STUDY DESIGN Study of patients with acute myocardial(More)
PURPOSE To compare the efficacy of carvedilol, a new antihypertensive drug that combines vasodilatory and beta-blocker properties, with nifedipine. METHODS In a multicenter double-blind trial, 106 mild to moderate essential hypertensive patients were treated with either carvedilol (n = 51), or nifedipine (n = 55) as monotherapy. Following 4 weeks of(More)
BACKGROUND Sleep apneas are frequent in patients with heart failure (HF). Estimate of the pre-beta blocker age (BB) point out to 45% of central apneas in these patients. OBJECTIVE Assess the influence of BB in central apneas and their interference in the quality of sleep and life of patients with heart failure. METHODS 65 patients with heart failure(More)
