|Impact Factor is a population statistic that reflects how many citations of a journalâs papers published over a two-year period receive during the subsequent year. âThe annual Journal Citation Reports impact factor is a ratio between citations and recent citable items published: a journalâs impact factor is calculated by dividing the number of current year citations to the source items published in that journal during the previous two years.
The life expectancy in Human Immunodeficiency Virus (HIV) infected patients is increased after the introduction of Highly Active Antiretroviral Therapy (HAART). However, there is a growing concern of cardiovascular disease, in general and peripheral arterial disease. Variety of atherogenic metabolic abnormalities including dyslipidemia, lipodystrophy and insulin resistance have been reported after the use of protease inhibitors (PI). Moreover, HIV causes direct injury to the arterial wall resulting in inflammation and atherosclerosis. This has led to the greater interest in detection of atherosclerosis by measuring carotid intimal thickening, endothelial dysfunction and coronary calcification.peripheral arterial disease is a focal manifestation of atherosclerosis and is a predictor of cardiovascular outcomes. In the majority of cases, patients with PAD remain asymptomatic. Therefore, early diagnosis of PAD may provide an opportunity for physicians to identify and prevent cardiovascular events in high-risk patients. The prevalence of PAD is higher in HIV-infected patients as compared to sex-matched non-HIV controls. Clinicians should routinely screen for PAD in HIV patients using simple tool like ABI measurement. Apart from correlation with cardiovascular risk factors, strong association between lower CD4 cell count and abnormal ABI exists.(Gupta N, Bajaj S, Shah P, Parikh R, Gupta I, The Prevalence of Peripheral Arterial Disease in HIV Patients)
