RESUMO
The so-called "smoking paradox", conditioning lower mortality in smokers among STEMI patients, has seldom been addressed in the settings of modern primary PCI protocols. The ISACS−STEMI COVID-19 is a large-scale retrospective multicenter registry addressing in-hospital mortality, reperfusion, and 30-day mortality among primary PCI patients in the era of the COVID-19 pandemic. Among the 16,083 STEMI patients, 6819 (42.3%) patients were active smokers, 2099 (13.1%) previous smokers, and 7165 (44.6%) non-smokers. Despite the impaired preprocedural recanalization (p < 0.001), active smokers had a significantly better postprocedural TIMI flow compared with non-smokers (p < 0.001); this was confirmed after adjustment for all baseline and procedural confounders, and the propensity score. Active smokers had a significantly lower in-hospital (p < 0.001) and 30-day (p < 0.001) mortality compared with non-smokers and previous smokers; this was confirmed after adjustment for all baseline and procedural confounders, and the propensity score. In conclusion, in our population, active smoking was significantly associated with improved epicardial recanalization and lower in-hospital and 30-day mortality compared with previous and non-smoking history.
RESUMO
AIMS: Spontaneous coronary artery dissection (SCAD) is a relatively rare but well-known cause of acute coronary syndrome. Clinical features, angiographic findings, management and outcomes of SCAD in old patients (>65 years of age) remain unknown. METHODS AND RESULTS: The Spanish multicentre prospective SCAD registry (NCT03607981), included 318 consecutive patients with SCAD. Data were collected between June 2015 and April 2019. All angiograms were analysed in a centralized corelab. For the purposes of this study, patients were classified according to age in two groups <65 and ≥65 years old and in-hospital outcomes were analysed. Fifty-five patients (17%) were ≥65 years old (95% women). Older patients had more often hypertension (76% vs. 29%, P < 0.01) and dyslipidaemia (56% vs. 30%, P < 0.01), and less previous (4% vs. 18%, P < 0.001) or current smoking habit (4% vs. 33%, P < 0.001). An identifiable trigger was less often present in old patients (27% vs. 43%, P = 0.028). They also had more often severe coronary tortuosity (36% vs. 11%, P = 0.036) and showed more frequently coronary ectasia (24% vs. 9%, P < 0.01). Older patients were more often managed conservatively (89% vs. 75%, P = 0.025), with no significant differences in major adverse cardiac events during index admission (7% vs. 8%, P = 0.858). There were no differences between groups in terms of in-hospital stay, new acute myocardial infarction, unplanned coronary angiography or heart failure. CONCLUSION: Older patients with SCAD show different clinical and angiographic characteristics compared with younger patients. Initial treatment strategy was different between groups, though in-hospital outcomes do not significantly differ (NCT03607981).

INTRODUCTION AND OBJECTIVES: To determine the difference in the risk of stent thrombosis between drug-eluting stents (DES) and bare-metal stents (BMS) and to assess the clinical implications. METHODS: A retrospective analysis of two cohorts of patients treated at our center with either > or =1 paclitaxeleluting stents (PES) (n=430) or > or =1 BMSs (n=1230) during 2003-2004 was carried out using propensity score methods to compare the adjusted risks of stent thrombosis, instent restenosis, cardiovascular death, acute myocardial infarction (AMI), and target-lesion revascularization with the two stent types. RESULTS: After a median follow-up of 46 months, there was a higher risk of stent thrombosis in PESs (hazard ratio [HR]=3; 95% confidence interval [CI], 1.2-7.1] though the risk of in-stent restenosis was lower (HR=0.3; 95% CI, 0.2-0.7]. There was no difference in the risk of cardiovascular death, AMI or target-lesion revascularization. With PESs, the risks of target-lesion revascularization (HR=0.33; 95% CI, 0.2-0.7) and in-stent restenosis (HR=0.32; 95% CI, 0.2-0.7) were reduced during the first year of follow-up. After this time, the risks of target-lesion revascularization (HR=1.8; 95% CI, 1-3.2) and very late stent thrombosis (HR=12.8; 95% CI, 3-55.1) both increased. CONCLUSIONS: Our findings indicate that the balance of risks and benefits of PESs compared with BMSs is different in the early and late periods after stent implantation. The greatly increased risk of very late stent thrombosis in PESs could cancel out the clinical benefits associated with the reduction in in-stent restenosis observed in PESs relative to BMSs.

A 72-year-old man presented with worsening shortness of breath and a systolic murmur. Transthoracic and transoesophageal echocardiograms revealed a huge mass (70 x 30 mm) obliterating the right ventricular outflow tract, with a peak transpulmonary gradient of 128 mmHg. Pathological examination confirmed the mass to be a primary cardiac rhabdomyosarcoma originating from the pulmonary valve.
