Is the higher risk of cardiovascular disease amongst South Asian populations linked to abnormalities of haemoglobin? A preliminary case control study.

The elevated burden of cardiovascular disease (CVD) amongst South Asian populations is a complex and multi-factorial phenomenon. South Asians evolved from environments where malaria was endemic, and while haemoglobin disorders frequent this group, a link to CVD has not been described. Using a case-control feasibility study, haemoglobin abnormalities identified by mass spectrometry were compared between South Asian patients with CVD (n = 72) and non-CVD controls (n = 84).

An evidence-based checklist for the postoperative management of obstructive sleep apnea.

Obstructive sleep apnea (OSA) can present significant challenges in providing postoperative care. OSA policies have been developed and are in place within many facilities; however, a standard OSA protocol ensuring the safe delivery of postoperative care has not been universally accepted into practice. A synthesis of current OSA literature led to the development of a comprehensive evidence-based checklist to improve patient safety and direct the management of postoperative care for diagnosed or suspected OSA patients throughout their hospitalization.

Glycemic status underlies increased arterial stiffness and impaired endothelial function in migrant South Asian stroke survivors compared to European Caucasians: pathophysiological insights from the West Birmingham Stroke Project.

Background: The pathophysiology of an increased risk of cerebrovascular disease mortality among South Asians (SA) remains unclear. Indices of arterial stiffness and endothelial dysfunction are independent markers of vascular disease, having both prognostic and diagnostic implications. We hypothesized that there are ethnic variations in indices of arterial stiffness and endothelial dysfunction between SA and European Caucasian (EC) stroke patients, which may underline a poorer prognosis in the former, and further investigated promoters of vessel wall abnormalities.

Ischemic stroke in South Asians: a review of the epidemiology, pathophysiology, and ethnicity-related clinical features.

Background And Purpose: Within the United Kingdom, mortality from stroke is higher among South Asians compared to European whites. The reasons for this excess cerebrovascular risk in South Asians remain unclear. The aim of this review is to present a comprehensive and systematic overview of the available literature relating to ischemic stroke among South Asian populations identifying distinct features of stroke epidemiology in this group.

Impact of mean arterial blood pressure on higher arterial stiffness indices in South Asians compared to white Europeans.

Background: The pathophysiology of excessive premature coronary heart disease mortality among South Asians living in Britain remains unclear. We hypothesized that higher measures of arterial stiffness among South Asians compared with their white European counterparts would reflect an earlier progression of atherosclerosis, even in the absence of established coronary heart disease risk indices.

Methods: Arterial stiffness was measured by digital volume pulse photoplethysmography in 90 healthy South Asians and compared with 62 matched white Europeans in a temperature-controlled environment using a direct, standardized approach.
