Objectives The objective of our work is to evaluate the prognostic benefit of an early invasive strategy in patients with high-risk NSTACS according to the recommendations of the 2020 clinical practice guidelines during long-term follow-up. Methods This retrospective observational study included 6454 consecutive NSTEACS patients. We analyze the effects of early coronary angiography (< 24 h) in patients with: (a) GRACE risk score > 140 and (b) patients with "established NSTEMI" (non ST-segment elevation myocardial infarction defined by an increase in troponins) or dynamic ST-T-segment changes with a GRACE risk score < 140. Results From 2003 to 2017, 6454 patients with "new high-risk NSTEACS" were admitted, and 6031 (93.45%) of these underwent coronary angiography. After inverse probability of treatment weighting, the long-term cumulative probability of being free of all-cause mortality, cardiovascular mortality and MACE differed significantly due to an early coronary intervention in patients with NSTEACS and GRACE > 140 [HR 0.62 (IC 95% 0.57-0.67), HR 0.62 (IC 95% 0.56-0.68), HR 0.57 (IC 95% 0.53-0.61), respectively]. In patients with NSTEACS and GRACE < 140 with established NSTEMI or ST/T-segment changes, the benefit of the early invasive strategy is only observed in the reduction of MACE [HR 0.62 (IC 95% 0.56-0.68)], but not for total mortality [HR 0.96 (IC 95% 0.78-1.2)] and cardiovascular mortality [HR 0.96 (IC 95% 0.75-1.24)]. Conclusions An early invasive management is associated with reduced all-cause mortality, cardiovascular mortality and MACE in NSTEACS with high GRACE risk score. However, this benefit is less evident in the subgroup of patients with a GRACE score < 140 with established NSTEMI or ST/T-segment changes.

Background: Clinical trials have assessed the effect of direct oral antagonists (DOACs) in patients with atrial fibrillation (AF) after percutaneous coronary interventions (PCI). Studies were designed to test the effect on bleeding incidence, but concerns related to safety on ischemic events remain. Methods: We performed a meta-analysis with currently available studies involving DOACs versus Vitamin-K antagonist (VKA) in patients with AF after PCI. The primary endpoint was the incidence of cardiac ischemic events, including myocardial infarction and stent thrombosis. Secondary endpoints were the incidence of stroke, all-cause mortality, and major bleeding. Results: Eleven thousand twenty-three patients were included in the analysis: 5510 receiving DOACs and 5513 VKA. A total of 190 cases of myocardial infarction were registered in patients treated with DOACs and 177 in patients on VKA, and no statistical difference was noted [relative risk (RR): 1.07 95% confidence interval (CI) 0.88-1.31]. The incidence of stent thrombosis was very low with no differences between both treatment strategies (RR: 1.14 95% CI 0.76-1.71). The incidence of cardiac ischemic events was the same in patients receiving DOACs or VKA (HR 1.09 95% CI 0.91-1.30). No differences were observed in the incidence of stroke (RR: 0.86 95% CI 0.61-1.23) or mortality (RR: 1.09, 95% CI 0.90-1.31). Treatment with DOACs was associated with 34% reduction in major bleeding (RR: 0.66, 95% CI 0.54-0.81). Conclusions: Treatment with DOACs in patients with AF after a PCI do not increase the risk of cardiac ischemic events, stroke, or death and reduce the incidence of major bleeding by 34% as compared with VKA.

Coronary artery disease is one of the leading causes of morbidity and mortality, and its prevalence increases with age. The growing number of older patients and their differential characteristics make its management a challenge in clinical practice. The aim of this review is to summarize the state-of-the-art in diagnosis and treatment of acute coronary syndromes in this subgroup of patients. This comprises peculiarities of ST-segment elevation myocardial infarction (STEMI) management, updated evidence of non-STEMI therapeutic strategies, individualization of antiplatelet treatment (weighting ischemic and hemorrhagic risks), as well as assessment of geriatric conditions and ethical issues in decision making.

Background: N-terminal pro-brain natural peptide (NT-pro-BNP) is a well-established biomarker of tissue congestion and has prognostic value in patients with heart failure (HF). Nonetheless, there is scarce evidence on its predictive capacity for HF re-admission after an acute coronary syndrome (ACS). We performed a prospective, single-center study in all patients discharged after an ACS. HF re-admission was analyzed by competing risk regression, taking all-cause mortality as a competing event. Results are presented as sub-hazard ratios (sHR). Recurrent hospitalizations were tested by negative binomial regression, and results are presented as incidence risk ratio (IRR). Results: Of the 2133 included patients, 528 (24.8%) had HF during the ACS hospitalization, and their pro-BNP levels were higher (3220 pg/mL vs. 684.2 pg/mL; p < 0.001). In-hospital mortality was 2.9%, and pro-BNP was similarly higher in these patients. Increased pro-BNP levels were correlated to increased risk of HF or death during the hospitalization. Over follow-up (median 38 months) 243 (11.7%) patients had at least one hospital readmission for HF and 151 (7.1%) had more than one. Complete revascularization had a preventive effect on HF readmission, whereas several other variables were associated with higher risk. Pro-BNP was independently associated with HF admission (sHR: 1.47) and readmission (IRR: 1.45) at any age. Significant interactions were found for the predictive value of pro-BNP in women, diabetes, renal dysfunction, STEMI and patients without troponin elevation. Conclusions: In-hospital determination of pro-BNP is an independent predictor of HF readmission after an ACS.

Background Routine manual thrombectomy (MT) is not recommended in primary percutaneous coronary intervention (P-PCI) but it is performed in many procedures. The objective of our study was validating the DDTA score, designed for selecting patients who benefit most from MT. Methods Observational and multicenter study of all consecutive patients undergoing P-PCI in five institutions. Results were compared with the design cohort and the performance of the DDTA was analyzed in all patients. Primary end-point of the analyses was TIMI 3 after MT; secondary endpoints were final TIMI 3, no-reflow incidence, in-hospital mortality and in-hospital major cardiovascular events (MACE). In-hospital prognosis was assessed by the Zwolle risk score. Results Three hundred forty patients were included in the validation cohort and no differences were observed as compared to the design cohort (618 patients) except for lower use of MT and higher IIb/IIIa inhibitors or drug-eluting stents. The probability of TIMI 3 after MT decreased as delay to P-PCI was higher. If DDTA score, MT was associated to TIMI 3 after MT (OR: 4.11) and final TIMI 3 (OR: 2.44). There was a linear and continuous relationship between DDTA score and all endpoints. DDTA score >= 4 was independently associated to lower no-reflow, in-hospital MACE or mortality. The lowest incidence of in-hospital mortality or MACE was in patients who had DDTA score >= 4 and Zwolle risk score 0-3. Conclusions MT is associated to higher rate of final TIMI3 in patients with the DDTA score >= 4. Patients with DDTA score >= 4 had lower no-reflow and in-hospital complications.
