To date, however, no study has shown that these effects can be demonstrated within hours after the onset of infarction. Furthermore, data are scarce on the independent impact of thrombolytic therapy and late vessel patency on ventricular volume and function. The aim of this study was to assess separate effects of thrombolysis and patency of the infarct-related artery on left ventricular size and function by serial two-dimensional echocardiographic examinations. METHODS AND RESULTS We evaluated 131 consecutive patients with first acute myocardial infarction by two-dimensional echocardiography in the following sequence: days 1, 2, 3, 7, and after 3 and 6 weeks. Intravenous streptokinase was administered in 81 patients, a...

It provides a review of recommended components for an effective cardiac rehabilitation/secondary prevention program, alternative ways to deliver these services, recommended future research directions, and the rationale for each component of the rehabilitation/secondary prevention program, with emphasis on the exercise training component.

Coronary artery anomalies are infrequent but anticipated findings during percutaneous coronary interventions (PCI). Compared to consistent reporting in angiographic series, they seem to be underreported in interventional studies, and particularly in the setting of primary PCI, where their prompt recognition is of the utmost importance. Case report. We present a 50 years old male with inferior ST-elevation of myocardial infarction (STEMI) and right ventricular involvement with solitary ostium for all three coronary arteries in the right aortic sinus of Valsalva. The patient had an extremely rare variant of coronary artery origination belonging to the type A4b2c2 of Angelini?s classification. Correspondingly, it belongs to the left Anomalous origination of a Coronary Artery from the Opposite Sinus of Valsalva (ACAOS) class with the intraseptal course of left anterior descending artery. We managed successfully to implant a drug eluting stent in the proximal right coronary...

It was supposed that BVS will reduce neointimal proliferation and that their late bioresorption will reduce the negative effects of traditional drug-eluting stents, including the late stent thrombosis, local vessel wall inflammation, loss of coronary vasoreactivity and the need for the long-term dual antiplatelet therapy. The purpose of this research was to investigate efficacy and safety of Absorb everolimus-eluting BVS implantation and the prevalence of major adverse cardiovascular events (MACE) at the mid-term follow-up. Methods: The study encompassed 42 patients selected for BVS implantation and fulfilling inclusion criteria - 37 male and 5 female - ...

Currently little data is available on the optimal management of DES restenosis. While there are many possible mechanical or lesion-based etiologies for DES restenosis, drug resistance may play a role. Hypothesis: We assessed the hypothesis that implantation of a different DES would be superior to implantation of the same DES for the treatment of DES restenosis. Methods: We identified all patients undergoing repeat DES implantation for DES restenosis in our institutions. The patients were divided into 2 groups: those receiving the same DES as the one that restenosed and those treated with the alternative DES. The endpoints analyzed were target lesion revascularization (TLR) and angiographic restenosis. Results: We included a total of 174 patients (201 lesions) treated between October 2002 and June 2005. The same DES was implanted in 107 lesions ...

Functional mitral regurgitation (FMR) is a common entity in patients with aortic stenosis (AS) undergoing aortic valve replacement (AVR). The aim of this study was to examine evolution of moderate and moderate to severe FMR after an isolated AVR, to identify prognostic indicators for persistent MR postoperatively, and to offer the recommendation regarding surgical intervention for moderate and moderate to severe FMR at the time of AVR for AS. Methods. We retrospectively reviewed 39 consecutive patients with moderate and moderate to severe FMR at the time of isolated AVR from January 2007 to December 2013. We collected preoperative and postoperative echocardiographic data to determine the evolution of FMR after AVR. Patients were divided into the persistent (n = 14) and improved FMR group (n = 25). Secondary division was into the prosthesis-patient mismatch (PPM, n = 7) and non prosthesis-patient mismatch group (non PPM, n = 32 patients). Late follow-up echocardiograp...
