The femoropopliteal artery is one of the commonest sites of involvement in peripheral artery disease (PAD) leading to intermittent claudication and/or critical limb ischemia. Endovascular therapy for superficial femoral artery (SFA) disease has been recognized as a safe and efficient therapy and is recommended by current guidelines as the first-line approach. Although the widespread use of new-generation, self-expanding, nitinol stents in SFA stenosis has reduced the shortcomings associated with plain old balloon angioplasty (POBA), lumen renarrowing at the stented (in-stent restenosis – ISR) level still represents a relevant clinical problem, because of higher risk of recurrent ISR, occlusion and surgical revascularization compared to de-novo lesions. In this setting, different treatment options are available and drug-coated balloons (DCBs) have shown good results in terms of safety and effectiveness. In this review we examine the results of different trials exploring the outcome of using DCBs for the treatment of SFA ISR. The available data demonstrate that SFA ISR can be safely treated with percutaneous transluminal angioplasty with a DCB, with a reduction in recurrent restenosis and target lesion revascularization (TLR) at least at 1 year after POBA. The consistent and positive results of different registries and randomized trials support the use of DCB to reduce SFA ISR recurrence.

Aims Adherence to medical therapy following acute coronary syndrome (ACS) affects a patient's prognosis. In this cohort study, we sought to assess the factors that could affect a patient's adherence to therapy after ACS. Methods We prospectively collected information from patients (N = 964) hospitalized at the coronary care unit of the Federico II University Hospital, from 1 January 2015 to 30 June 2017, for ACS. Adherence to three classes of drugs including statins, antiplatelets [dual or single antiplatelet agent (SAPT)] and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACE-I/ARB) and their composites were assessed at 1 month, 1 and 2 years after discharge. Results At 30 days adherence to prescribed therapy was 94.4% for dual antiplatelet therapy (DAPT), 78.2% for statins, 92.7% for ACE-I/ARB and 70.7% for multitherapy. At 1 year, it was 91.1% for DAPT, 81.2% for ACE-I/ARB, 84.9% for statins and 71.4% for multitherapy. At 2 years, it was 97.1% for SAPT, 78.1% for ACE-I/ARB, 91.8% for statins, 72.8% for multitherapy. Multivariable logistic analysis demonstrated that at each time point, a telephone follow-up assessment predicts nonadherence to multitherapy and that a percutaneous coronary intervention at the index hospitalization is an independent predictor of adherence to composite therapy at 1 month and 1 year. Conclusion Up to 2 years after ACS, three out of four patients are adherent to multitherapy prescription; percutaneous coronary intervention during the index hospitalization improves a patient's adherence, whereas telephone follow-up is associated with reduced adherence to multitherapy.
