Acute effect of coffee on aortic stiffness and wave reflections in healthy individuals: differential effect according to habitual consumption

The acute effect of coffee on arterial stiffness and its dependence on habitual consumption was studied in 24 volunteers on four separate occasions during which subjects received: (a) coffee espresso, (b) decaffeinated coffee espresso, (c) caffeine alone and (d) placebo (hot water). The increase in carotid femoral pulse wave velocity (PWV), augmentation index (AIx) and augmented pressure (AP) of the aortic pressure waveform after coffee consumption was more pronounced in non-habitual (n = 13) compared to habitual drinkers (n = 11), (differences of maximal changes between groups in PWV, AIx, AP responses by 0.39 m/s, 4.5% and 1.9 mmHg, respectively, for coffee; and by 0.34 m/s, 5.3% and 2.1 mmHg, respectively, for decaffeinated coffee; all p <.05). Caffeine increased PWV, as well as AIx and AP but differences in responses between the two groups were not significant. Both caffeinated and decaffeinated coffee consumption is associated with a more potent effect on arterial stiffness in non-habitual than habitual coffee consumers, whereas caffeine induces comparable changes in both groups. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group

Resolute italian study in all comers: Immediate and One-Year Outcomes

Objectives: To assess clinical performance of the second-generation Endeavor Resolute(®) drug-eluting stents (DES) in an unrestricted high-risk cohort of patients. Background: New-generation DESs aim to further increase its clinical safety and efficacy by means of more biocompatible components limiting inflammatory response, assuring strut coverage and preserving endothelial vascular function. Methods: Between January 2008 and April 2009 820 unselected consecutive high-risk patients (1,352 lesions) treated with the Endeavor Resolute(®) stent were enrolled in an independent multicenter registry. Primary end-points of this registry were immediate procedural outcome, incidence of target lesion failure (TLF, defined as composite of cardiac death, myocardial infarction, and target lesion revascularization) and rate of ARC stent thrombosis at 12-months follow-up. Results: High-risk patient/lesion profile included acute coronary syndrome diagnosis in 57% of patients, diabetes mellitus in 23% and ACC/AHA type B2/C lesion in 74%. Endeavor Resolute(®) stent was used in an off-label indication in 52% of cases with stent/patient ratio of 1.93 and average stented segment of 39.8±26.6mm. Immediate procedural success was accomplished in 96.0% of cases and at median 12-month follow-up TLF rate was 7.1% with 4.0% of clinically driven repeat revascularizations and 1.1% of definite/probable stent thrombosis incidence. At multivariable analysis, nor off-label Endeavor Resolute(®) stent use or multiple stent implantations were associated to an increased risk of adverse events. Conclusions: Extensive use of the new Endeavor Resolute(®) stent was associated with favorable procedural and 12-month outcomes despite the treatment of unselected complex clinical and anatomical presentation. Endeavor Resolute(®) stent showed excellent safety and efficacy profile also in off-label indications. © 2011 Wiley-Liss, Inc

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

Aims The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. Methods and results Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (inhospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, prehospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. Conclusion The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality
