RESUMO

BACKGROUND: The optimal strategy and timing of revascularization in hemodynamically stable patients with ST-segment elevation myocardial infarction and multivessel disease is unknown. We performed a systematic review and meta-analysis to explore the comparative efficacy and safety of early complete revascularization vs culprit-only or staged revascularization in this setting. METHODS: We searched the literature for randomized clinical trials that assessed this issue. Early complete revascularization was defined as a complete revascularization achieved during the index procedure or within 72 hours. Efficacy outcomes were major adverse cardiovascular events, myocardial infarction, repeat revascularization, and all-cause mortality. Safety outcomes were all bleeding events, stroke, and contrast-induced acute kidney injury. RESULTS: Nine randomized clinical trials with a total of 2837 patients were included; 1254 received early complete revascularization and 1583 were treated with other revascularization strategies. After a mean follow-up of 15.3 ± 9.4 months early complete revascularization was associated with a lower risk of major adverse cardiovascular events (relative risk [RR], 0.51; 95% confidence interval [CI], 0.41-0.62; P < 0.00001; number needed to treat = 8), myocardial infarction (RR, 0.59; 95% CI, 0.40-0.87), and repeat revascularization (RR, 0.39; 95% CI, 0.28-0.55) without any difference in all-cause mortality and in safety outcomes compared with culprit-only or staged revascularization. Moreover, fractional flow reserve-guided complete revascularization reduced the incidence of repeat revascularization compared with angiography-guided procedure (χ2 = 4.36; P = 0.04). CONCLUSIONS: Early complete revascularization should be considered in hemodynamically stable patients with ST-segment elevation myocardial infarction and multivessel disease deemed suitable for percutaneous interventions. Fractional flow reserve-guided complete revascularization might be superior to angiography-guided procedures in reducing need for further interventions.

RESUMO

AIMS: To systematically review literature comparing bare metal stent (BMS) to drug-eluting stent (DES) in end-stage renal disease (ESRD) patients on dialysis. ESRD patients on dialysis often suffer from accelerated atherosclerosis and higher rate of stent-related complications including major adverse cardiovascular events. Because dialysis usually qualifies ineligibility for randomized clinical trials, an evidenced-based stent choice for these patients is scarce. METHODS: PUBMED, CINHAL, COCHRANE, EMBASE and WEB OF SCIENCE were searched for studies comparing BMS vs. DES outcome in ESRD patients on dialysis. RESULTS: Twenty studies including 64 232 patients were considered. The use of DES was significantly associated with a reduction in all-cause mortality [odds ratio (OR) 0.83, 95% confidence interval (CI) 0.76-0.89], death from a cardiovascular cause (OR 0.80, 95% CI 0.76-0.84) and target lesion revascularization/target vessel revascularization (OR 0.73, 95% CI 0.53-1.00). No significant difference was found in stent thrombosis (OR 1.08, 95% CI 0.50-2.33) and myocardial infarction incidence (OR 0.91, 95% CI 0.69-1.20). CONCLUSIONS: Our meta-analysis shows a significant reduction in all-cause and cardiovascular mortality with the use of DES over BMS in dialyzed patients. Despite the lack of randomized studies, systematic use of DES in these high-risk patients should thus reasonably be considered as a first option in percutaneous coronary intervention candidates.

RESUMO

Incomplete ST resolution after primary percutaneous coronary interventions (pPCI) in STEMI patients is a well known prognostic marker, associated with the occurrence of microvascular obstruction and increased mortality. The effects of the use of glycoprotein IIbIIIa inhibitors (GPIs) in this peculiar subset of high- risk patients is still unknown. The aim of the present study was to assess whether the GPIs administration would result in improved outcome in ST elevation myocardial infarction (STEMI) patients with incomplete ST resolution (ISTR). All consecutive STEMI patients who underwent pPCI at our hospital between 2005 and 2014 were enrolled (n = 2001). ST resolution was defined as incomplete with a < 70% resolution of initial ST shift. Mortality analyses were performed by Kaplan-Meier curves, multivariable analysis through Cox regressions and propensity matching score. The incidence of ISTR was 29% (n = 592). Among ISTR patients, GPIs use was an independent predictor of better prognosis (HR 0.39, 95% CI 0.16-0.96, p < 0.04). Propensity matched analysis confirmed that the use of GPIs was associated with a lower 30-day (6.1% vs 13.4%, p = 0.02) and 1-year (8.4% vs 15.1%, p = 0.045) mortality. STEMI patients treated with pPCI and presenting ISTR show a poor outcome. The use of GPIs in these patients is associated with improved survival at 30 days and at 1 year; the causes for these favorable effects remain speculative and could be related to the development and evolution of microvascular obstruction.

RESUMO

BACKGROUND: Implantable cardioverter-defibrillator (ICD) is an effective therapy to reduce mortality in heart failure. When the ICD generator approaches the end of life, most of the patients undergo an elective generator replacement (GR) even if they no longer meet implantation criteria. Whether arrhythmic risk should be re-assessed at the time of GR is still an open question. The aim of our study was to assess, via a meta-analysis, the occurrence of appropriate ICD therapies after GR in patients stratified based on the presence/absence of ICD indication at the time of GR. METHODS: Via a systematic literature search for primary prevention studies (January 2000-Sectember 2018), 2976 studies were analyzed. 6 studies were lastly included. Patients were categorized into two groups: "with ICD indication" in case of LVEF≤35% at the time of GR and/or appropriate therapies during the first ICD life; "without ICD indication" in case of a LVEF>35% and no previous ICD therapies. Incidences of appropriate ICD therapies were computed as number of events per 100 person-year. RESULT: We included 478 pts. (65%) with and 255 patients (35%) without persistent ICD indication. The incidence of appropriate therapies was 12.3/100-person-year in patients with vs. 3.4 in patients without persistent ICD indication (2.98 fold higher risk of ICD therapies). CONCLUSION: Patients who no longer meet ICD implantation criteria at the time of GR present a significantly lower risk of appropriate ICD therapies after GR. The results of this study underline the importance of an arrhythmic risk re-stratification at the time of GR.

RESUMO

BACKGROUND AND AIMS: There is contrasting evidence regarding the optimal antithrombotic regimen after percutaneous coronary stent implantation in patients on oral anticoagulants. A systematic review and meta-analysis was performed to explore the comparative efficacy and safety of dual (an antiplatelet plus an oral anticoagulant) versus triple therapy (dual antiplatelet therapy plus an oral anticoagulant). METHODS: We searched the literature for randomized controlled trials (RCTs) or observational studies (OSs) addressing this issue. The efficacy outcomes were all-cause mortality, cardiovascular mortality, myocardial infarction and stent thrombosis. The safety outcomes were major bleeding events and all bleeding events. The analyses were stratified by type of anticoagulant and of antiplatelet used in dual therapy. RESULTS: Four RCTs and ten OSs met our inclusion criteria including a total of 10,126 patients. 5671 patients received triple therapy whereas 4455 received dual therapy. Median follow up was 12 months. There was no difference between dual therapy and triple therapy regarding efficacy outcomes. Dual therapy significantly reduced the risk of major bleeding (RR 0.66; CI 95% 0.52-0.83; P = 0.0005) and of all bleeding events (RR 0.67, CI 95% 0.55-0.80; P < 0.0001). The effect was consistent regardless of the type of antiplatelet and anticoagulant used in dual therapy. CONCLUSION: Dual antithrombotic therapy after coronary stenting in anticoagulated patients significantly reduces bleeding events compared with triple therapy. Dual therapy might be considered in this setting especially when bleeding risk outweighs ischemic risk, although our study was not sufficiently powered to detect a difference in ischemic endpoints.

RESUMO

Patients with end-stage heart failure (HF), pulmonary hypertension and elevated pulmonary vascular resistance (PVR) despite medical therapy are not eligible for heart transplantation (HTx). In this 'proof of concept' case series, we demonstrate the feasibility and efficacy of the MitraClip procedure as 'bridge to list' in end-stage HF patients not eligible for HTx. In fact, in the three patients reported, who were initially excluded from the HTx list because of elevated PVR, the MitraClip procedure was followed by a sustained improvement of PVR, allowing the patients' risk to be reclassified, and they were then considered eligible for HTx.

RESUMO

BACKGROUND: There is a growing interest in exploring the concept of right ventricular functional reserve in patients with pulmonary arterial hypertension. However, it is still unclear how it should be assessed. Aim of the study was to investigate the determinants of the changes in cardiac output and in pulmonary pressure during dobutamine stress echocardiography in pulmonary arterial hypertension. METHODS: Low-dose dobutamine stress echocardiography was performed in 55 patients and 28 controls. Tricuspid annular plane systolic excursion, its ratio to systolic pulmonary artery pressure, right ventricular area change, degree of tricuspid regurgitation, right ventricular end-systolic pressure-area ratio, cardiac output were assessed at rest and at peak stress. RESULTS: According to the stress induced increase in cardiac output, patients were classified into 2 groups: above/equal to the median of 2.8 L/min (high cardiac output) or below the median (low cardiac output). High cardiac output patients were characterized by a greater increase in heart rate (+45.1 ±â€¯17.5 vs +21.3 ±â€¯17.7 bpm), a greater improvement in tricuspid annular plane systolic excursion (+4.2 ±â€¯3.3 vs +1.9 ±â€¯2.6 mm, P = 0.005) and a decrease in tricuspid regurgitation (P = 0.010) as compared to low cardiac output patients. Changes in pulmonary pressure were not associated with changes in indicators of right ventricular function but only with changes in heart rate. CONCLUSIONS: The increase in cardiac output during dobutamine is associated with an improvement in longitudinal right ventricular function, a decrease in tricuspid regurgitation and an increase in heart rate. Changes in pulmonary pressure only reflect the changes in heart rate.

RESUMO

AIMS: About one-third of ischemic stroke are cryptogenic. Paradoxical embolism through patent foramen ovale (PFO) has been identified as a possible cause of cryptogenic stroke. Therefore, PFO closure has been considered for secondary prevention of cryptogenic stroke. However, randomized clinical trials (RCTs) comparing PFO closure versus medical therapy led to conflicting results. Our objectives were to examine if PFO closure is superior to medical therapy alone for secondary prevention of cryptogenic stroke and to investigate whether PFO closure is associated with an increased incidence of atrial fibrillation/atrial flutter (AFL). METHODS: The authors systematically searched MEDLINE for RCTs that compared PFO closure with medical therapy. Efficacy outcome was cerebrovascular event (CVE) recurrence and safety outcome was new-onset atrial fibrillation/AFL. The outcomes of interest were investigated according to device type with subgroup analyses and meta-regression. RESULTS: The authors included eight RCTs constituting 4114 patients. Patients who underwent PFO closure had a lower risk of CVE recurrence compared with medically treated patients [relative risk (RR): 0.56; 95% confidence interval (CI) 0.40-0.80; P = 0.001; I = 30%]. This protective effect was consistent across the different device types. Patients who underwent PFO closure developed more frequently atrial fibrillation/AFL (RR 4.96; 95% CI 2.74-8.99; P < 0.00001; I = 0%), which was mainly transient and within 1 month. Atrial fibrillation/AFL risk was consistent according to device types, although marginally significant in the Amplatzer subgroup. CONCLUSION: PFO closure might have a role in secondary CVE prevention of patients with PFO and cryptogenic stroke. However, it is associated with an increased incidence of new-onset atrial fibrillation/AFL especially within 1 month.

RESUMO

AIMS: Elevated serum uric acid (eSUA) was associated with unfavorable outcome in patients with ST-segment elevation myocardial infarction (STEMI). However, the effect of eSUA on myocardial reperfusion injury and infarct size has been poorly investigated. Our aim was to correlate eSUA with infarct size, infarct size shrinkage, myocardial reperfusion grade and long-term mortality in STEMI patients undergoing primary percutaneous coronary intervention. METHODS: We performed a post-hoc patients-level analysis of two randomized controlled trials, testing strategies for myocardial ischemia/reperfusion injury protection. Each patient underwent acute (3-5 days) and follow-up (4-6 months) cardiac magnetic resonance. Infarct size and infarct size shrinkage were outcomes of interest. We assessed T2-weighted edema, myocardial blush grade (MBG), corrected Thrombolysis in myocardial infarction Frame Count, ST-segment resolution and long-term all-cause mortality. RESULTS: A total of 101 (86.1% anterior) STEMI patients were included; eSUA was found in 16 (15.8%) patients. Infarct size was larger in eSUA compared with non-eSUA patients (42.3 ±â€Š22 vs. 29.1 ±â€Š15 ml, P = 0.008). After adjusting for covariates, infarct size was 10.3 ml (95% confidence interval 1.2-19.3 ml, P = 0.001) larger in eSUA. Among patients with anterior myocardial infarction the difference in delayed enhancement between groups was maintained (respectively, 42.3 ±â€Š22.4 vs. 29.9 ±â€Š15.4 ml, P = 0.015). Infarct size shrinkage was similar between the groups. Compared with non-eSUA, eSUA patients had larger T2-weighted edema (53.8 vs. 41.2 ml, P = 0.031) and less favorable MBG (MBG < 2: 44.4 vs. 13.6%, P = 0.045). Corrected Thrombolysis in myocardial infarction Frame Count and ST-segment resolution did not significantly differ between the groups. At a median follow-up of 7.3 years, all-cause mortality was higher in the eSUA group (18.8 vs. 2.4%, P = 0.028). CONCLUSION: eSUA may affect myocardial reperfusion in patients with STEMI undergoing percutaneous coronary intervention and is associated with larger infarct size and higher long-term mortality.

RESUMO

BACKGROUND: Patients with diabetes mellitus (DM) and acute coronary syndromes have a greater level of platelet aggregation and a poor response to oral antiplatelet drugs. Clopidogrel is still widely used in clinical practice, despite the current evidence favoring ticagrelor and prasugrel. AIM: The aim of this study was to investigate the determinants of clopidogrel use in the population of the multicenter prospective 'Acute Coronary Syndrome and Diabetes Registry' carried out during a 9-week period between March and May 2015 at 29 Hospitals. PATIENTS AND METHODS: A total of 559 consecutive acute coronary syndrome patients [mean age: 68.7±11.3 years, 50% ST-elevation myocardial infarction (STEMI)], with 'known DM' (56%) or 'hyperglycemia' at admission, were included in the registry; 460 (85%) patients received a myocardial revascularization. RESULTS: At hospital discharge, dual antiplatelet therapy was prescribed to 88% of the patients (clopidogrel ticagrelor and prasugrel to 39, 38, and 23%, respectively). Differences in P2Y12 inhibitor administration were recorded on the basis of history of diabetes, age, and clinical presentation (unstable angina/non-STEMI vs. non-STEMI). On univariate analysis, age older than 75 years or more, known DM, peripheral artery disease, previous myocardial infarction, previous revascularization, complete revascularization, previous cerebrovascular event, creatinine clearance, unstable angina/non-STEMI at presentation, Global Registry of Acute Coronary Events Score, EuroSCORE, CRUSADE Bleeding Score, and oral anticoagulant therapy were significantly associated with clopidogrel choice at discharge. On multivariate analysis, only oral anticoagulant therapy and the CRUSADE Bleeding Score remained independent predictors of clopidogrel prescription. CONCLUSION: In the present registry of a high-risk population, clopidogrel was the most used P2Y12 inhibitor at hospital discharge, confirming the 'paradox' to treat sicker patients with the less effective drug. Diabetic status, a marker of higher thrombotic risk, did not influence this choice; however, bleeding risk was taken into account.

RESUMO

Aims To compare clinical outcome in Chronic kidney disease (CKD) patients receiving coronary stents according to stent type BMS versus DES and 1st generation versus 2nd generation DES. Methods and Results PubMed, Cinhal, Cochrane, Embase, and Web of Science were searched for studies including CKD patients. CKD was defined as eGFR < 60 mL/min. We selected n = 35 articles leading to 376 169 patients, of which 76 557 CKD patients receiving BMS n = 35,807, 1st generation DES n = 37,650, or 2nd generation DES n = 3100. Patient receiving DES, compared to BMS, had a 18% lower all-cause mortality (RR 0.82, 95%CI 0.71-0.94). The composite of death or myocardial infarction (MI) was lower in DES patients (RR 0.78, 95%CI 0.67-0.91), as was stent thrombosis (ST) (RR 0.57, 95%CI 0.34-0.95), target vessel/lesion revascularization (TVR/TLR) (RR 0.69, 95%CI 0.57-0.84) and death for cardiovascular cause (RR 0.43, 95%CI 0.25-0.74). We also found a gradient between 1st and 2nd generation DES, through BMS. Second, compared to 1st generation DES, were associated with further relative risk (RR) reduction of -18% in of all-cause death, and lower incidence of stent-related clinical events: -39% RR of ST risk; -27 RR of TVR/TLR risk. Conclusions DES in CKD patients undergoing PCI were superior to BMS in reducing major adverse clinical events. This was possibly explained, by a lower risk of stent-related events as ST and TVR or TLR. Second, compared to 1st generation DES may furtherly reduce clinical events.

RESUMO

AIMS: The most recent European guidelines have proposed new definitions of pulmonary hypertension (PH) in left heart disease, to better approach the characteristics required to reflect the presence of pulmonary vascular disease. The purpose of this study was to assess whether different haemodynamic definitions of post-capillary PH imply a different reversibility of PH in response to acute vasodilator administration in heart failure patients with reduced ejection fraction and PH (HFrEF-PH). METHODS AND RESULTS: Right heart catheterization and reversibility testing was performed in 156 HFrEF-PH patients. Patients were classified as combined post-capillary and pre-capillary pulmonary hypertension (Cpc-PH) vs. isolated post-capillary pulmonary hypertension (Ipc-PH) and on the basis of diastolic pulmonary gradient (DPG) ≥ 7 vs. < 7 mmHg or of transpulmonary gradient (TPG) >12 vs. ≤12 mmHg. After vasodilator administration, Cpc-PH patients showed a greater per cent improvement in pulmonary vascular resistance (PVR), DPG and TPG as compared with Ipc-PH patients (all Pint < 0.001); only pulmonary compliance (PCa) improved less in Cpc-PH than in Ipc-PH patients (Pint = 0.007). However, despite vasodilatation, Cpc-PH patients remained in an unfavourable portion of the inverse hyperbolic relationship between PVR and PCa. The number of patients in whom PVR was reduced below 2.5 wood units was similar in Cpc-PH, DPG ≥7 mmHg and TPG >12 mmHg groups (28.3, 26.7 and 18.9%, respectively). CONCLUSION: Although substantial improvements in PVR, DPG and TPG were observed in Cpc-PH patients after acute vasodilator administration, this response was associated with persistent abnormalities in the PVR vs. PCa relationship. The link between baseline right heart haemodynamics and pulmonary vascular disease remains elusive.

RESUMO

BACKGROUND: The hemodynamic definitions of pulmonary hypertension (PH) in left heart disease have recently been refined to better match the characteristics required to reflect the presence of pulmonary vascular disease. Accordingly, we tested the hypothesis that abnormalities in the stiffness of pulmonary circulation would persist after heart transplantation in patients with combined post-capillary and pre-capillary PH (Cpc-PH) in contrast to those with isolated post-capillary PH (Ipc-PH). METHODS: We retrospectively analyzed right heart hemodynamics in a cohort of 295 consecutive patients with heart failure and advanced left ventricular systolic dysfunction (LVSD) before and 1 year after heart transplantation. RESULTS: According to their baseline hemodynamic profile, patients were classified as: 75 Cpc-PH, 111 Ipc-PH, and 98 without PH (no-PH), and 11 pre-capillary PH. One year after heart transplantation, pulmonary artery pressures, pulmonary vascular resistance and cardiac index normalized in all patients regardless of the baseline hemodynamic profile. However, pulmonary arterial compliance remained lower in Cpc-PH patients (from 1.6±1.2 at baseline to 3.7±1.4 ml/mmHg at 1 year) than in Ipc-PH (from 1.2±2.0 to 4.4±2.3 ml/mmHg) and no-PH patients (from 3.7±2.0 to 4.5±1.8 ml/mmHg); (adjusted p = 0.03 Ipc-PH vs. Cpc-PH INT<0.001). CONCLUSIONS: In heart failure patients with advanced LVSD, a hemodynamic profile characterized by Cpc-PH predicts the persistence of a stiffer pulmonary circulation at 1 year after heart transplantation.

RESUMO

Several studies established a link between bleeding and mortality in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI); however, it is unclear whether bleeding has a direct role in worsening the prognosis or if it is simply a marker of patient frailty. We investigated whether bleeding is an independent predictor of mortality in patients with STEMI treated with pPCI. The relationship between the presence of heart failure on presentation (Killip classification), bleeding occurrence, and outcome was also assessed. Bleeding was defined as the combination of Thrombolysis in Myocardial Infarction major and minor bleeding. Short- and long-term mortalities were estimated using the Kaplan-Meyer analysis. Multivariable analysis was performed by the Cox regression model. As an alternative method to address the potential confounding factors, we performed a propensity-matched analysis adjusted for all variables included in the CRUSADE score. In the 1,911 consecutive patients with STEMI considered, bleeding (observed in 11.4% of patients) was an independent predictor of 30-day (hazard ratio 2.61, 95% confidence interval 1.30 to 5.25, p = 0.007) and 1-year mortality (hazard ratio 1.98, 95% confidence interval 1.13 to 3.47, p = 0.017) but not in a landmark analysis starting from 30 days to 1 year. Bleeding was significantly associated with higher 30-day and 1-year mortality in patients with Killip class ≥II, but not in patients with Killip class I. In conclusion, in-hospital bleeding is independently associated with increased mortality in the early period after STEMI, also after adjusting for variables associated with the risk of bleeding. Bleeding was associated with increased mortality in patients with signs of heart failure at admission, whereas it had no effects in patients with Killip class I.
