- Female gender has been shown to be associated with worse clinical outcomes after percutaneous coronary intervention (PCI). However, the impact of gender on the clinical outcomes of complex PCI is still poorly understood. This study examined the differences in patient and coronary lesion characteristics and longer-term clinical outcomes in male and female patients who underwent complex PCI. This was a sub-analysis of the e-ULTIMASTER study, which was a large, multicontinental, prospective, observational study enrolling 37,198 patients who underwent PCI with the Ultimaster stent. Patients who underwent complex PCI were stratified by gender. The primary outcome was target lesion failure at 12 months, defined as the composite of cardiac death, target vessel-related myocardial infarction, and clinically driven target lesion revascularization at 12 months. A total of 13,623 patients underwent complex procedures, of which 35.7% were women. Women were twice as likely as men to be aged ≥80 years (17.6% vs 9%, p <0.0001) and had a higher prevalence of cardiovascular risk factors. Women had fewer lesions treated than men (1.5 ± 0.8 vs 1.6 ± 0.8, p <0.0001) and fewer stents implanted (2.0 ± 1.1 vs 2.1 ± 1.1, p <0.0001). There was no statistically significant difference in clinical outcomes at 12 months between women and men. Event rates were comparable in women and men for target lesion failure (4.7% vs 4.3%, p = 0.30), target vessel failure (5.1% vs 4.9%, p = 0.73), and cardiac death (1.8% vs 1.7%, p = 0.80).In conclusion, our findings suggest no significant differences in clinical outcomes between women and men who underwent complex PCI.

- BACKGROUND—: Thrombus aspiration during percutaneous coronary intervention (PCI) for the treatment of ST elevation myocardial infarction (STEMI) has been widely used; however, recent trials have questioned its value and safety. In this meta-analysis, we, the trial investigators, aimed to pool the individual patient data from these trials to determine the benefits and risks of thrombus aspiration during PCI in patients with STEMI. METHODS—: Included were large (N≥1000) randomized controlled trials comparing manual thrombectomy vs. PCI alone in patients with STEMI. Individual patient data was provided by the leadership of each trial. The pre-specified primary efficacy outcome was cardiovascular (CV) mortality within 30 days and the primary safety outcome was stroke or transient ischemic attack (TIA) within 30 days. RESULTS—: The 3 eligible randomized trials (TAPAS, TASTE and TOTAL) enrolled 19,047 patients, of whom 18,306 underwent PCI and were included in the primary analysis. CV death at 30 days occurred in 221 (2.4%) of 9155 patients randomized to thrombus aspiration and 262 (2.9%) of 9151 randomized to PCI alone (hazard ratio (HR) 0.84; 95% CI 0.70-1.01, p=0.06). Stroke or TIA occurred in 66 (0.8%) randomized to thrombus aspiration and 46 (0.5%) randomized to PCI alone (odds ratio [OR] 1.43 95% CI 0.98-2.1, p=0.06). There were no significant differences in recurrent myocardial infarction, stent thrombosis, heart failure or target vessel revascularization. In the subgroup with high thrombus burden (TIMI thrombus grade ≥3) thrombus aspiration was associated with less CV death (170 [2.5%] vs. 205 [3.1%] HR 0.80; 95% CI 0.65-0.98, p =0.03), and with more stroke or TIA (55 [0.9%] vs. 34 [0.5%] OR 1.56; 95% CI 1.02-2.42, p=0.04). However, the interaction p-values were 0.32 and 0.34, respectively. CONCLUSIONS—: Routine thrombus aspiration during STEMI PCI did not improve clinical outcomes. In the high thrombus burden subgroup the trends toward reduced CV death and increased stroke or TIA provide a rationale for future trials of improved thrombus aspiration technologies in this high-risk subgroup.

There were no significant differences in recurrent myocardial infarction, stent thrombosis, heart failure, or target vessel revascularization. In the subgroup with high thrombus burden (TIMI [Thrombolysis in Myocardial Infarction] thrombus grade >= 3), thrombus aspiration was associated with fewer cardiovascular deaths (170 [2.5%] versus 205 [3.1%]; hazard ratio, 0.80; 95% confidence interval, 0.65-0.98; P=0.03) and with more strokes or transient ischemic attacks (55 [0.9%] versus 34 [0.5%]; odds ratio, 1.56; 95% confidence interval, 1.02-2.42, P=0.04).

- Aims Primary percutaneous coronary intervention (PPCI) is the preferred reperfusion therapy in ST-elevation myocardial infarction (STEMI). We conducted this study to evaluate the contemporary status on the use and type of reperfusion therapy in patients admitted with STEMI in the European Society of Cardiology (ESC) member countries. Methods and results A cross-sectional descriptive study based on aggregated country-level data on the use of reperfusion therapy in patients admitted with STEMI during 2010 or 2011. Thirty-seven ESC countries were able to provide data from existing national or regional registries. In countries where no such registries exist, data were based on best expert estimates. Data were collected on the use of STEMI reperfusion treatment and mortality, the numbers of cardiologists, and the availability of PPCI facilities in each country. Our survey provides a brief data summary of the degree of variation in reperfusion therapy across Europe. The number of PPCI procedures varied between countries, ranging from 23 to 884 per million inhabitants. Primary percutaneous coronary intervention and thrombolysis were the dominant reperfusion strategy in 33 and 4 countries, respectively. The mean population served by a single PPCI centre with a 24-h service 7 days a week ranged from 31 300 inhabitants per centre to 6 533 000 inhabitants per centre. Twenty-seven of the total 37 countries participated in a former survey from 2007, and major increases in PPCI utilization were observed in 13 of these countries. Conclusion Large variations in reperfusion treatment are still present across Europe. Countries in Eastern and Southern Europe reported that a substantial number of STEMI patients are not receiving any reperfusion therapy. Implementation of the best reperfusion therapy as recommended in the guidelines should be encouraged.

- Aims: Preliminary studies suggest that direct stenting (DS) during percutaneous coronary intervention (PCI) may reduce microvascular obstruction and improve clinical outcome. Thrombus aspiration may facilitate DS. We assessed the impact of DS on clinical outcome and myocardial reperfusion and its interaction with thrombus aspiration among ST-segment elevation myocardial infarction (STEMI) patients undergoing PCI.Methods and results: Patient-level data from the three largest randomized trials on routine manual thrombus aspiration vs. PCI only were merged. A 1:1 propensity matched population was created to compare DS and conventional stenting. Synergy between DS and thrombus aspiration was assessed with interaction P-values in the final models. In the unmatched population (n= 17329), 32% underwent DS and 68% underwent conventional stenting. Direct stenting rates were higher in patients randomized to thrombus aspiration as compared with PCI only (41% vs. 22%; P < 0.001). Patients undergoing DS required less contrast (162 mL vs. 172 mL; P < 0.001) and had shorter fluoroscopy time (11.1 min vs. 13.3 min; P < 0.001). After propensity matching (n = 10944), no significant differences were seen between DS and conventional stenting with respect to 30-day cardiovascular death [1.7% vs. 1.9%; hazard ratio 0.88, 95% confidence interval (CI) 0.55-1.41; P=0.60; P-interaction = 0.96) and 30-day stroke or transient ischaemic attack (0.6% vs. 0.4%; odds ratio 1.02; 95% CI 0.14-7.54; P= 0.99; P-interaction = 0.81). One-year results were similar. No significant differences were seen in electrocardiographic and angiographic myocardial reperfusion measures.Conclusion: Direct stenting rates were higher in patients randomized to thrombus aspiration. Clinical outcomes and myocardial reperfusion measures did not differ significantly between DS and conventional stenting and there was no interaction with thrombus aspiration.

- Background: Accurate 1-year bleeding risk estimation after hospital discharge for acute coronary syndrome(ACS) may help clinicians guide the type and duration of antithrombotic therapy. Currently there are no predictive models for this purpose. The aim of this study was to derive and validate a simple clinical tool for bedside risk estimation of 1-year post-discharge serious bleeding in ACS patients.Methods: The risk score was derived and internally validated in the BleeMACS (Bleeding complications in a Multicenter registry of patients discharged with diagnosis of Acute Coronary Syndrome) registry, an observational international registry involving 15,401 patients surviving admission for ACS and undergoing percutaneous coronary intervention (PCI) from 2003 to 2014, engaging 15 hospitals from 10 countries located in America, Europe and Asia. External validation was conducted in the SWEDEHEART population, with 96,239 ACS patients underwent PCI and 93,150 without PCI.Results: Seven independent predictors of bleeding were identified and included in the BleeMACS score: age, hypertension, vascular disease, history of bleeding, malignancy, creatinine and hemoglobin. The BleeMACS risk score exhibited a C-statistic value of 0.71 (95% CI 0.68-0.74) in the derivation cohort and 0.72 (95% CI 0.67-0.76) in the internal validation sample. In the SWEDEHEART external validation cohort, the C-statistic was 0.65 (95% CI 0.64-0.66) for PCI patients and 0.63 (95% CI 0.62-0.64) for non-PCI patients. The calibration was excellent in the derivation and validation cohorts.Conclusions: The BleeMACS bleeding risk score is a simple tool useful for identifying those ACS patients at higher risk of serious 1-year post-discharge bleeding.
