Current state of angina treatment in the outpatient population and heart rate monitoring survey in Latvia (relity latvia)

The aim of the REALITY Latvia survey was to accumulate information about treated stable angina outpatients regarding their characteristics, heart rate (HR), treatment, and quality of life. Thirty cardiologists were involved with 1-15 patients each. In total, data about 300 patients were obtained. Patients were examined and questioned during one visit. A high HR was defined above 70 beats per minute (bpm), in accordance to recent evidence. Mean HR was 70.3 ± 11.3 bpm and 45% of patients had HR above 70 bpm. The opinion of practitioners regarding HR differed. For example, a HR level within the range 70-80 bpm was perceived by cardiologists as “normal”, “borderline high” and “high”. The mean target HR that physicians wanted to achieve was 60.1 ± 4.7 bpm. Beta blockers were used in 91% of cases. The more widely used beta blockers were metoprolol (47%) and bisoprolol (35%) in mean daily doses 69.7 ± 30.1 mg and 5.3 ± 2.0 mg, respectively. REALITY Latvia data suggest that, despite wide use of beta blockers, HR control in stable angina patients is insufficient. This is caused by insufficient understanding of HR as a treatment target by physicians and use of beta blockers in suboptimal dosages.publishersversionPeer reviewe

Copyright: Copyright 2014 Elsevier B.V., All rights reserved.Introduction Improvement in coronary heart disease prevention and treatment, as well as availability of coronary care facilities, is important for the reduction of acute coronary syndrome (ACS) incidence. Centralized acute coronary care system is crucial to provide optimal hospitalization and management algorithm for ACS patients. Aim The aim of the current report was to assess the annual incidence of ACS and the quality of acute coronary care in Latvia. Methods The Data from The Latvian Registry of Acute Coronary Syndromes were analyzed covering the time period from 2005 to 2010. Results Since the year 2005 the annual incidence of hospitalization due to ACS decreased significantly in Latvia. The annual incidence of non-ST-elevation ACS (NSTE-ACS) decreased from 8019 to 4613 in absolute numbers based on the registry data during six years. Improvement in the use of guidelines based therapy and early invasive strategy in ACS patients was observed. Increase in primary percutaneous coronary intervention was achieved from 7.9% in 2005 to 57.0% in 2010, contributing to reduction in the proportion of STEMI patients without any reperfusion (from 45% in 2005 to 21% in 2010). Conclusions The annual incidence of hospitalized ACS, especially NSTE-ACS, decreased and guidelines based management of ACS improved from 2005 to 2010 in Latvia.publishersversionPeer reviewe

Are Paclitaxel-Eluting Stents Better in Unprotected Left Main Coronary Artery Disease? Three-Year Clinical and Intravascular Imaging Results From a Randomized Study

Background and Objective. Recent publications have demonstrated superior outcomes in unprotected left main patients after paclitaxel-eluting stent (PES) implantation. Long-term data in these patients are limited. The aim of this study was to evaluate if intravascular ultrasound (IVUS)-guided PES implantation is superior to bare metal stent (BMS) implantation in unprotected left main disease after lesion pretreatment with cutting balloon during long-term follow-up. Material and Methods. Unprotected left main patients were randomized to BMS (n=50) or PES implantation (n=53). All interventions were IVUS-guided and cutting balloon pretreatment before stenting was performed in all patients. All patients were scheduled for 6-month and 3-year follow-up. Subgroups of patients who underwend IVUS and OCT imaging at 3-year follow-up were analyzed. The primary endpoint was the major adverse cardiac events (MACEs) defined as death, Q-wave myocardial infarction, or target lesion revascularization. Results. Baseline characteristics were similar in both the groups with a mean SYNTAX score of 31.4±14.5 in BMS and 32.6±11.7 in PES patients (P=0.718). At 3 years, MACEs occurred in 18 patients (36.0%) in the BMS and 7 patients (13.2%) in the PES group (P=0.011). By IVUS, percent neointimal volume obstruction at 3 years was reduced from 18.1%±8.7% with BMSs to 10.0%±5.4% with PESs (P<0.001). The total number of uncovered stent struts per OCT image and IVUS image was 0.4±0.8 and 1.2±1.5, respectively (P<0.001). Conclusions. The current study demonstrated that IVUS-guided PES implantation was superior to BMS implantation after cutting balloon pretreatment in unprotected left main disease at 3 years. If compared with IVUS, OCT was more precise in the assessment of stent endothelization
