Cardiovascular disease in Hajj pilgrims.

The changing pattern of hospital admissions during Hajj, the Muslims yearly pilgrimage attracting millions of pilgrims from all around the globe, has gradually seen infectious causes of hospital admission replaced by cardiovascular diseases as a leading cause of both intensive care unit admission and death. While this trend is partly associated with the high quality of medical services and awareness programs targeted at reducing the spread of infections, at the same time it underscores an urgent need to establish a pragmatic system to manage the challenge of cardiovascular morbidities and mortality during Hajj. SEARCH STRATEGY AND INCLUSION CRITERIA: A PubMed Central (PMC) literature search without date restrictions was performed for articles reporting on the medical experience during Hajj. There were 109 articles were returned using "Hajj" and "mortality" as search terms.

Data from these studies reporting on the pattern and outcome of hospitalization during Hajj were examined and helped in arriving at the conclusions presented in this review.
