Abstract Background Polymer-free (PF) stents were designed as an alternative to durable-polymer (DP) drug-eluting stents to minimize the time on dual antiplatelet treatment for patients at high-risk of bleeding. Nonetheless, the efficacy and safety of PF vs. DP stents in patients undergoing percutaneous coronary intervention (PCI) remain controversial. Methods We performed a metanalysis with currently available studies that assessed the effect of PF-stents vs. DP-stents after performing a systematic search. The endpoints analyzed were all-cause death, myocardial infarction, target lesion revascularization (TLR) and probable or definite stent thrombosis. The raw numbers of incident end-points reported in each study were used. We performed analyses in short and long term (<1 or >1 year follow-up) studies. Results We included 12464 patients from 8 studies (5 short-term and 3 long-term): 6723 treated with PF-stents and 5741 with DP stents. Females represented 23.3% (n=3284) and 33.7% (n=4202) were included in the setting of acute coronary syndromes. As shown in the figure, PF-stents were associated to lower incidence of all-cause mortality (HR: 0.91 95% CI 0.84–0.98; p=0.016) and TLR (HR: 0.88 95% CI 0.80–0.96; p=0.003). No differences were observed in the risk of cardiovascular death (HR: 0.96 95% CI 0.86–1.06 p=0.415), myocardial infarction (HR: 0.90 95% CI 0.80–1.01; p=0.061) or probable-definite stent thrombosis (HR: 0.92 95% CI 0.74–1.14; p=0.447). Finally, no differences in the primary end-point (HR: 0.92 95% CI 0.83–1.03; p=0.143) were detected with PF-stents vs. DP-stents. No significant heterogenicity was observed in any of the endpoints, except for the incidence of stent thrombosis. Conclusions Under current PCI techniques the use of PF-stent might be associated to better outcomes, especially in terms of all-cause mortality and TLR.

Aim: Our aim was to investigate the characteristics, treatment and prognosis of patients with myocardial infarction (MI) treated outside a cardiology department (CD), compared with MI patients treated at a CD. Methods: A cohort of 1310 patients diagnosed with MI at eight Swedish hospitals in 2011 were included in this observational study. Patients were followed regarding all-cause mortality until 2018. Results: A total of 235 patients, exclusively treated outside CDs, were identified. These patients had more non-cardiac comorbidities, were older (mean age 83.7 vs. 73.1 years) and had less often type 1 MIs (33.2% vs. 74.2%), in comparison with the CD patients. Advanced age and an absence of chest pain were the strongest predictors of non-CD care. Only 3.8% of non-CD patients were investigated with coronary angiography and they were also prescribed secondary preventive pharmacological treatments to a lesser degree, with only 32.3% having statin therapy at discharge. The all-cause mortality was higher in non-CD patients, also after adjustment for baseline parameters, both at 30 days (hazard ratio (HR) 2.28; 95% confidence interval (CI) 1.62–3.22), one year (HR 1.82; 95% CI 1.39–2.36) and five years (HR 1.62; 95% CI 1.32–1.98). Conclusions: MI treatment outside CDs is associated with an adverse short- and long-term prognosis. An improved use of percutaneous coronary intervention (PCI) and secondary preventive pharmacological treatment might improve the long-term prognosis in these patients.

Background. Anemia following acute myocardial infarction (AMI) is associated with poor outcomes. While previous studies in patients with AMI have focused on anemia at admission, we hypothesized that hemoglobin (Hb) decline during hospitalization and lower discharge Hb would be associated with greater long-term mortality in patients undergoing primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI). Methods. We analyzed records of 983 STEMI patients who were treated with primary PCI. The primary end point was all-cause mortality at 1 year and 2 years. The relationship between discharge Hb levels, decline in Hb levels, bleeding event classification, and all-cause mortality was determined. Results. Overall, 16.4% of patients had bleeding events, which were classified by the Thrombolysis in Myocardial Infarction (TIMI) score as 7% minimal, 8.6% minor, and 0.9% major. No significant gastrointestinal bleed and cerebral hemorrhage occurred in hospitals among these patients. The incidence rate of the 2-year all-cause mortality increased with severity of the bleeding event score (8.78% for no bleeding vs. 11.59% for minimal bleeding vs. 20.24% for minor bleeding vs. 55.56% for major bleeding, P<0.001). Discharge Hb was significantly associated with 2-year mortality in an unadjusted model (hazard ratio (HR) per 1 g/L decrease in discharge Hb = 1.020, 95% confidence interval (CI): 1.006–1.034, P=0.004) and in a confounder-adjusted model (HR per 1 g/L decrease in discharge Hb = 1.024, 95% CI: 1.011–1.037, P<0.001). The odds ratio (OR) for all-cause mortality at 2 years for participants with Hb below the twentieth percentile was 3.529 (95% CI: 1.976–6.302) and 2.968 (95% CI: 1.614–5.456) after adjustment for age and gender and 2.485 (95% CI: 1.310–4.715) after adjustment for all covariates. Conclusions. In this population of patients hospitalized for STEMI, all-cause mortality increased with lower discharge Hb, and discharge Hb was a significant predictor of mortality risk.

Abstract Background The appropriate treatment for silent myocardial ischemia (SMI) is controversial. The prognosis of asymptomatic patients after percutaneous coronary intervention (PCI) is unknown. Asymptomatic patients might be sicker and have delay of diagnosis when they have coronary events in clinical course. We, thus, hypothesized SMI are associate with the poor outcomes after PCI for stable coronary artery disease (CAD). Purpose The present study compared the long-term outcomes of patients with SMI vs. stable angina pectoris (SAP) after elective PCI. Methods Our prospective registry database included 923 consecutive patients with CAD who underwent PCI from October 2015 to August 2018. Patients with emergent PCI, acute coronary syndrome at admission, or chronic total occlusion patients were not included. A total 613 patients (71.4±11.2 years, 75.7% male) who underwent elective PCI were studied. The end points included all-cause mortality, non-fatal myocardial infarction, and repeat revascularization. Results They were divided into 2 groups according to symptom status: SMI (n=392) and SAP (n=221). SMI patients were predominantly men, and more frequently had diabetes mellitus (197 [50.4%] vs. 91 [41.2%], p=0.028), previous myocardial infarction (44 [11.3%] vs. 8 [3.6%], p=0.001) and heart failure hospitalization.Echocardiography showed SMI groups had reduced ejection fraction (56.9±12.6 vs 63.3±9.1, P&lt;0.001), extended left ventricular internal dimension in diastole (48.5±6.2 vs 47.4±5.8, p=0.048) and left ventricular diameter at end systole (32.8±7.6 vs 30.5±7.5, p=0.001). Mean duration of follow-up was 20.9±10.6 months. The incidence of non-fatal myocardial infarction and repeat revascularization was similar between the 2 groups (10 [2.6%] vs. 5 [2.3%], p=0.82, and 50 [12.8%] vs. 30 [13.6%], p=0.77, respectively). The incidence of all-cause and cardiovascular mortality was more frequent in SMI patients (26 [6.6%] vs. 6 [2.7%], p=0.036, and 9 [3.1%] vs 1 [0.5%], p=0.035, respectively). Kaplan-Meier survival curves indicated that SMI patients had significantly higher all cause-mortality than SAP patients (log-rank, p=0.0184, Hazard ratio 1.24 (1.05–1.47), p=0.013). In multivariable analysis, SMI was an independent predictor of all cause-mortality (Hazard-ratio 5.17, 95% CI 1.35–34.29, p=0.014). Conclusion In patients with stable CAD undergoing elective PCI, SMI was associated with an increase in mortality. Optimal care for SMI patients after PCI should be clarified in future studies.

Objectives: To evaluate the effects of occurrence and timing of sudden cardiac arrest (SCA) on survival in patients with acute myocardial infarction (AMI) who underwent emergency percutaneous coronary intervention (PCI).Methods: We analyzed 1,956 consecutive patients with AMI with emergency PCI from 2014 to 2018. Patients with cardiac arrest events were identified, and their medical records were reviewed.Results: Patients were divided into non-cardiac arrest group (NCA group, n = 1,724), pre-revascularization cardiac arrest (PRCA group, n = 175), and post-revascularization SCA (POCA group, n = 57) according to SCA timing. Compared to NCA group, PRCA group and POCA group presented with higher brain natriuretic polypeptide (BNP), more often Killip class 3/4, atrial fibrillation, and less often completed recovery of coronary artery perfusion (all p &lt; 0.05). Both patients with PRCA and POCA showed increased 30-day all-cause mortality when compared to patients with NCA (8.0 and 70.2% vs. 2.9%, both p &lt; 0.001). However, when compared to patients with NCA, patients with PRCA did not lead to higher mortality during long-term follow-up (median time 917 days) (16.3 vs. 18.6%, p = 0.441), whereas patients with POCA were associated with increased all-cause mortality (36.3 vs. 18.6%, p &lt; 0.001). Multivariate analysis identified Killip class 3/4, atrial fibrillation, high maximum MB isoenzyme of creatine kianse, and high creatinine as predictive factors for POCA. In Cox regression analysis, POCA was found as a strong mortality-increase predictor (HR, 8.87; 95% CI, 2.26–34.72; p = 0.002) for long-term all-cause death.Conclusions: POCA appeared to be a strong life-threatening factor for 30-day and long-term all-cause mortality among patients with AMI who admitted alive and underwent emergency PCI. However, PRCA experience did not lead to a poorer long-term survival in patients with AMI surviving the first 30 days.

Background: Despite advances in technology and technique, a substantial proportion of patients still die within several years after percutaneous coronary intervention (PCI). The relative rates of cardiovascular and noncardiovascular death after PCI remain uncertain. Methods and Results: We pooled individual patient-level data from 21 randomized clinical trials of PCI performed in 32 882 patients. All studies had independent adjudication of clinical events. We calculated the relative ratio of cardiovascular to noncardiovascular death in each trial up to 5 years and identified predictors of all-cause, cardiovascular, and noncardiovascular death. At the end of the follow-up period, 1980 patients had died (Kaplan-Meier estimated mortality rate, 9.19%). The rates of cardiovascular and noncardiovascular mortality at 5 years were 4.23% (945) and 5.17% (1035), respectively. The rate of cardiovascular death was higher than noncardiovascular death in the first 30 days after PCI (relative ratio, 6.99; 95% confidence interval, 3.16–15.42; P <0.001), similar between 30 days and 1 year, and lower between 1 and 5 years (relative ratio, 0.70; 95% confidence interval, 0.58–0.84; P =0.0005). Any adverse cardiac event (definite stent thrombosis, spontaneous myocardial infarction, or repeat revascularization) preceded cardiovascular and noncardiovascular mortality in 292 (30.9%) and 151 (14.6%) patients, respectively. In a multivariable model with adverse events entered as time-adjusted covariates, myocardial infarction and definite ST were associated with early and late all-cause and cardiovascular mortality but not noncardiovascular mortality. Conclusions: In this large-scale study of patients undergoing PCI, the 5-year rates of cardiovascular and noncardiovascular mortality were similar, but their relative timing was different.

Background The clinical importance of intraprocedural stent thrombosis (IPST) during percutaneous coronary intervention in the contemporary era of potent oral P2Y12 inhibitors is not established. The aim of this study was to assess IPST and its association with clinical outcome in patients with myocardial infarction undergoing percutaneous coronary intervention with contemporary antithromboticmedications. Methods and Results The VALIDATE‐SWEDEHEART study (Bivalirudin Versus Heparin in ST‐Segment and Non–ST‐Segment Elevation Myocardial Infarction in Patients on Modern Antiplatelet Therapy in the Swedish Web System for Enhancement and Development of Evidence‐Based Care in Heart Disease Evaluated According to Recommended Therapies Registry Trial) included 6006 patients with myocardial infarction, treated with potent P2Y12 inhibitors during percutaneous coronary intervention. IPST, defined as a new or worsening thrombus related to a stent deployed during the procedure, was reported by the interventional cardiologist in 55 patients (0.9%) and was significantly associated with ST‐segment elevation myocardial infarction presentation, longer stents, bailout glycoprotein IIb/IIIa inhibitors, and final Thrombolysis in Myocardial Infarction flow <3. The primary composite end point included cardiovascular death, myocardial infarction, out‐of‐laboratory definite stent thrombosis and target vessel revascularization within 30 days. Secondary end points were major bleeding and the individual components of the primary composite end point. Patients with versus without IPST had significantly higher rates of the primary composite end point (20.0% versus 4.4%), including higher rates of cardiovascular death, target vessel revascularization, and definite stent thrombosis, but not myocardial infarction or major bleeding. By multivariable analysis, IPST was independently associated with the primary composite end point (hazard ratio, 3.82; 95% CI, 2.05–7.12; P <0.001). Conclusions IPST is a rare but dangerous complication during percutaneous coronary intervention, independently associated with poor prognosis, even in the current era of potent antiplatelet agents. Future treatment studies are needed to reduce the rate of IPST and to improve the poor outcome among these patients.

Abstract Aims We aim to investigate the effect of single dose of statin pretreatment prior to primary Percutaneous Coronary Intervention (PCI) on long-term clinical outcomes in patients with ST-elevation Myocardial Infarction (STEMI). Methods Using data from China Acute myocardial Infarction (CAMI) registry, we compared the outcome in STEMI patients with vs without atorvastation pretreatment prior to primary PCI. The primary endpoint was the composite outcome of all-cause mortality, non-fatal MI or stroke events during follow-up. Propensity-score (PS) matching was used to assemble a cohort of patients with similar baseline characteristics. All patients were followed till 24 months since baseline. Results Of all 3772 patients who met our inclusion criteria at 108 hospitals in China, 3288 patients (1644 patients in each arm) were included in our PS-matched cohort. In the PS-match cohort, overall 144 (8.65%) and 113 (6.79%) patients in the control group and pretreatment group had the primary endpoint respectively (p=0.048). The estimated HRs were 0.78 (95% CI: 0.606–0.997, p=0.046) in the unadjusted model and 0.76 (95% CI: 0.596–0.984, p=0.032) in the adjusted model (Figure). The HRs were broadly similar for the pretreatment dosage of 40 mg or 80 mg (0.78 vs 0.77, p=0.75). The HRs were even stronger in patients with single-vessel only than multi-vessel coronary artery disease (0.31 vs 0.75, p=0.014). Conclusion Among Chinese patients with STEMI, atorvastatin pretreatment before primary PCI may have better long-term composite outcome of all-cause mortality, non-fatal MI, or stroke events.

Objective: To evaluate the incidence rate of definite stent thrombosis and major adverse cardiovascular events (MACE) with Ticagrelor versus Clopidogrel in ST segment elevation myocardial infarction (STEMI) patients candidate for primary percutaneous coronary intervention (PCI). Methods: STEMI participants naïve to antiplatelets, with no history of coronary artery disease (CAD) and candidate for primary PCI were included, while participants with history of CAD were excluded. Two hundred consecutive participants were selected, divided into 2 groups of 100 participants each, received either Ticagrelor or Clopidogrel, and followed up at 3 and 6 months. Results: The percent of patients in the Ticagrelor group who developed definite stent thrombosis (in-hospital and total) was 0%, while the percent of patients in the Clopidogrel group who developed definite stent thrombosis (in-hospital and total) was 8% and 9%, respectively. There were statistically significant weak associations between the class of P2Y12 platelet inhibitors and definite stent thrombosis (in-hospital and total) (X2 = 8.33, P = .004, V = 0.204 and Χ2 = 9.424, P = .002, V = 0.217, respectively). The percent of patients in the Ticagrelor and Clopidogrel groups who developed in-hospital MACE was 1% and 9%, respectively. There was a statistically weak significant association between the class of P2Y12 platelet inhibitors and in-hospital MACE (X2 = 6.74, P = .009, V = 0.184). Conclusion: Ticagrelor is more efficacious than Clopidogrel in preventing definite stent thrombosis (in-hospital and total) and in-hospital MACE in STEMI patients.
