This emerging problem is due to the antiretroviral therapy success that allows HIV-positive patients to live longer. Increased coronary heart disease rates in the HIV population, as in the noninfected population, may be related to traditional risk factors, including advancing age, higher smoking rates, dyslipidemia, insulin resistance, and impaired glucose tolerance. Some nontraditional factors have to be considered too: these are due to the direct effects of the virus on the vasculature, as well as to direct effects of specific antiretroviral drugs, including inflammation, endothelial dysfunction, metabolic disorders, prothrombotic state, and changes in body composition with loss of subcutaneous fat and/or accumulation of visceral fat. The aim of this paper is to review traditional and emerging cardiovascular risk factors and consider their possible interactions in HIV-infected patients.

We report a case of a 66 year-old male who experienced very late stent thrombosis at 5 years after paclitaxel-eluting stent (PES) implantation and 3 days after clopidogrel withdrawal. Intravascular ultrasound (IVUS) performed during the index procedure showed that the previously implanted PES was undersized. Since the patient could not take clopidogrel, we treated him with only a noncompliant balloon (3.0 × 15 mm) with optimal expansion as confirmed by IVUS. This case report describes a patient who continued clopidogrel treatment for 5 years and was probably protected from a procedural failure. During the current hospitalization, the patient was found to be a responder to clopidogrel after a platelet function assessment with Multiplate (Dynabyte Informationssysteme GmbH, Munich, Germany).

On the other hand, long-span antiretroviral therapy administration still raises questions on its long-term safety in an era in which life expectancy is becoming longer and longer while treatment of non-HIV-related serious events is increasingly raising concern. In this article, we will critically analyse the current knowledge of pathological and clinical aspects pertaining to the increased risk of cardiovascular events associated with HIV.

A minimum of 200 healthy women at risk for pregnancy were to be treated for a total of 6 cycles per patient in a prospective, randomized open parallel-group multicenter trial. Two hundred and forty-one subjects were randomized, 115 to DSG/EE and 126 to GSD/EE. Compliance to the study preparation was high (around 95%) in both groups and no pregnancies occurred during the study. Cycle control was excellent; there were no differences between the two groups with regard to incidence of spotting and breakthrough bleeding or duration and intensity of withdrawal bleeding. Side-effects were mild and in general comparable in the two groups. Both at baseline and during treatment, a higher proportion of women taking GSD/EE complained about breast tenderness. ...

We analysed the diagnostic accuracy of multi-detector row spiral computed tomography (MDCT) in determining mid- to high-grade coronary artery stenoses (> 50%). Sixty-nine patients with suspected CAD were referred to MDCT coronary angiography. Patients with a heart rate above 60 bpm received 20-40 mg propranol before the scan. The left main (LM), the left anterior descending artery (LAD), the first diagonal branch (D1), the right coronary artery (RCA) and the proximal tract of the circumflex artery (LCX) were independently evaluated by two blinded observers and screened for > 50% stenoses. The mean values of MDCT coronary narrowings assessed by two observers were compared to quantitative coronary angiography. MDCT correctly detected 95 of 123 coronary lesions (sensitivity 77.2%) and absence of stenoses was correctly identified in 388 of 426 segments (specifi...

Important elements to consider before approaching a bifurcation include angle and anatomy, in particular the take off angle (proximal angle, A) that is between the proximal MB and SB and the carina angle (distal angle, B) that is between distal main branch (MB) and side branch (SB) and also the extent and distribution of disease on the side branch and its size. Many techniques have been used to treat coronary bifurcation lesions such as provisional stenting or double stenting but no consensus technique has been accepted primarily due to variation of disease severity, angle and anatomy. Angle B is the unique statistically significant independent predictor factor influencing outcomes. Bifurcation angle and anatomy are important predictors of short and long-term outcomes after bifurcation treatment. Moreover we should evaluate it after wiring MB and SB so as after pre-di...
