Questions and answers on the use of aspirin for primary prevention of cardiovascular disease in diabetes
No full textPatients with diabetes have a prothrombotic state and a 2 to 4 times higher risk of cardiovascular events than those without diabetes. Aspirin is the cornerstone of treatment in patients withcardiovascular disease, irrespective of diabetes status, being able to confer a 19% relative risk reduction per year in serious vascular events compared with placebo at long-term follow-up (6.7% vs 8.2% per year, p < 0.0001). Data regarding the benefit-risk ratio of aspirin prescribed to patients with diabetes without established cardiovascular disease are less convincing, especially when compared to other preventive strategies. Of note, in primary prevention trials, aspirin allocation yielded a significant 12% proportional reduction in serious vascular events, irrespective of diabetes status, corresponding to a small annual absolute risk reduction (0.06% per year). However, in everyday clinical practice aspirin is still largely prescribed by both diabetologists and cardiologists. In this article, we provide eight questions and answers corroborated by available evidence on the use of aspirin for primary prevention of cardiovascular disease in diabetes
OBSERVANT II: Studio osservazionale per la valutazione di efficacia delle procedure transcatetere con dispositivi di nuova generazione nel trattamento della stenosi aortica sintomatica severa. Protocollo di studio
No full textBACKGROUND:
The rapid spread of transcatheter aortic valve implantation (TAVI) for the treatment of severe symptomatic aortic stenosis in the last decade in Italy has led to a gradually increasing use of TAVI procedures also in patients potentially eligible for aortic valve replacement (AVR). For this subset of patients, the OBSERVANT study (2011-2012) evaluated the short- and medium term outcome of TAVI vs AVR, at least for the first generations of TAVI devices, but failed to gather information on all the technological innovations occurred in recent years. The launch of a phase II of the study will allow to recruit a new series of TAVI, with different risk profiles compared with the historical OBSERVANT TAVI cohort, in order to assess whether and how much the use of new-generation devices mitigate the differences in outcomes recorded in the OBSERVANT study.
METHODS:
OBSERVANT II is an observational multicenter, prospective, cohort study collecting data on patients with severe symptomatic aortic stenosis undergoing TAVI in Italian hospitals since December 15, 2016, for at least 12 months. For each patient, data on demographic characteristics, health status, type of intervention and presence of comorbidities will be collected. Mortality and incidence of in-hospital major adverse cardiac and cerebrovascular events (MACCE) within 36 months of intervention will be the primary adverse outcome. Secondary outcomes will include 30-day mortality and the incidence of MACCE at 12 and 24 months. The statistical hypotheses were formulated considering the results from the OBSERVANT study. Testing these hypotheses will require the recruitment of at least 823 new TAVI. The risk/propensity-adjustment techniques will be used to comparatively evaluate the effectiveness of TAVI vs AVR.
EXPECTED RESULTS:
Safety and efficacy profiles of the new-generation TAVI prosthesis; comparative effectiveness of the new TAVI prosthesis as compared to TAVI procedures of the OBSERVANT historical cohort; comparative effectiveness of the new TAVI prosthesis as compared to AVR procedures of the OBSERVANT historical cohort.
CONCLUSIONS:
The results of OBSERVANT II will provide information on the effectiveness of TAVI employing new-generation devices and will be a valuable support to give professionals and policy makers evidence-based results useful for decision-making processes

No full textIn literature, there are limited data comparing ischemic mitral regurgitation (I-MR) versus nonischemic MR regarding outcomes after percutaneous edge-to-edge repair. We aimed to describe the early and 12-month results after MitraClip device implantation regarding the 2 etiologies. From January 2011 to December 2012, the Transcatheter Valve Treatment Sentinel Pilot Registry included 452 patients with MR who underwent MitraClip procedure in 25 centers across Europe. The prevalent etiology was I-MR (235 patients, 52.0%). I-MR group had a significantly higher proportion of men (74.9 vs 59.9%, p <0.001) and surgical risk (logistic EuroSCORE 24.8 ± 18.2 vs 18.8 ± 16.3, p <0.001). Acute procedural success was high (96%) and similar between groups (p = 0.48). Patients with I-MR required a higher, albeit not significant, number of clips to reduce MR (p = 0.08). Inhospital mortality was low (2.0%) without significant differences between etiologies. The estimated 1-year mortality and rehospitalization rates were 15.0% and 25.8%, respectively, without significant differences between groups. Paired echocardiographic data showed a persistent improvement of MR at 1 year in both etiologies. Despite a significant overall reverse atrial remodeling after clip, there were no significant changes in left ventricular volumes. In conclusion, this large independent cohort showed that percutaneous edge-to-edge therapy was associated with early- and long-term improvement of MR severity and functional condition both in patients with I-MR and nonischemic MR. There were no significant differences between the 2 etiologies regarding survival and freedom from rehospitalization due to heart failure at the 1-year follow-up

Full text linkIn type 2 diabetes, anti-thrombotic management is challenging, and current anti-platelet agents have demonstrated reduced efficacy. Old and new anti-diabetic drugs exhibited-besides lowering blood glucose levels-direct and indirect effects on platelet function and on thrombotic milieu, eventually conditioning cardiovascular outcomes. The present review summarizes existing evidence on the effects of glucose-lowering agents on platelet properties, addressing pre-clinical and clinical research, as well as drug-drug interactions with anti-platelet agents. We aimed at expanding clinicians' understanding by highlighting new opportunities for an optimal management of patients with diabetes and cardiovascular disease. We suggest how an improvement of the thrombotic risk in this large population of patients may be achieved by a careful and tailored combination of anti-diabetic and anti-platelet therapies
