Migrant South Asian population in the West, particularly women, is more predisposed to central obesity and metabolic syndromes than native Caucasians. However, the burden of coexistence of clinical risk factors for cardiovascular disease (CVD) and associated gender disparities in native population of South Asia are not known. We analyzed the National Health Survey of Pakistan (NHSP) (1990-1994) data to study the same in the population of Pakistan. ⋯ Potentially modifiable factors including obesity and saturated fat intake are associated with increased prevalence of CVD risk factors. The high burden of multiple CVD risk factors in women compared to men highlight the need for targeting this vulnerable segment of population in CVD prevention programs in Pakistan, and, possibly neighbouring countries.

Randomized Controlled Trial
The role of high-frequency jet ventilation in the treatment of Cheyne-Stokes respiration in patients with chronic heart failure.
Cheyne-Stokes respiration with central sleep apnea (CSR-CSA) is common in patients with severe cardiac failure. Various modes of positive airway pressure have been suggested as treatments. The authors hypothesized that high frequency jet ventilation (HFJV) can improve central sleep apnea in patients with chronic heart failure. ⋯ One night of therapy with HFJV improved nocturnal breathing pattern and sleep quality in patients with Cheyne-Stokes respiration in chronic heart failure. HFJV therapy for sleep and breathing were the same as those during a nasal CPAP night. A long-term study of the effect of HFJV on cardiovascular function is needed.

This study was performed to evaluate and compare the early, intermediate, and long-term outcomes of the bidirectional Glenn procedure and Fontan procedure in patients who live at moderately high altitude. ⋯ The bidirectional Glenn procedure can be used for long-term palliation of patients with a functionally single ventricle. Additional palliation with a Fontan procedure may increase the risk of stroke, protein losing enteropathy and arrhythmias without improving survival.

The aim of this study was to assess whether platypnea and orthodeoxia occur in Fontan patients. We divided 14 Fontan patients into 2 groups: 8 patients who had pulmonary arteriovenous fistulas and/or intra-atrial shunts (group A) and 6 patients who had neither pulmonary arteriovenous fistulas nor intra-atrial shunts (group B). They were compared with 9 controls (group C). ⋯ All groups showed the ventilatory equivalent was significantly higher in the sitting position than in the supine position (p < 0.05 to 0.01). We demonstrated platypnea and orthodeoxia in Fontan patients with pulmonary arteriovenous fistulas and intra-atrial shunts. We believe platypnea and orthodeoxia should be regard as a complication in Fontan patients with pulmonary arteriovenous fistulas and/or intra-atrial shunts.
