Complete revascularization for patients with multivessel coronary artery disease and ST-segment elevation myocardial infarction after the COMPLETE trial: A meta-analysis of randomized controlled trials

Background: The recently published COMPLETE trial has demonstrated that patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease (MVD), who underwent successful percutaneous coronary intervention (PCI) of both culprit and non-culprit (vs. culprit-only) lesions had a reduced risk of major adverse cardiac events (MACE), but not of cardiovascular or total mortality. The aim of this meta-analysis was to assess the efficacy of complete revascularization on cardiovascular or total mortality reduction using available randomized controlled trials (RCTs) including the COMPLETE trial, in hemodynamically stable STEMI patients with MVD. Methods: PubMed, MEDLINE, Embase, Scopus, Google Scholar, CENTRAL and ClinicalTrials.gov databases search identified 10 RCTs of 7033 patients with STEMI and MVD which compared complete (n = 3420) vs. only culprit lesion (n = 3613) PCI for a median 27.7 months follow-up. Random effect risk ratios were used to estimate for efficacy and safety outcomes. Results: Complete revascularization reduced the risk of MACE (10.4% vs.16.6%; RR = 0.59, 95% CI: 0.47 to 0.74, p < 0.0001), CV mortality (2.87% vs. 3.72%; RR = 0.73, 95% CI: 0.56 to 0.95, p = 0.02), reinfarction (5.1% vs. 7.1%; RR = 0.67, 95% CI: 0.52 to 0.86, p = 0.002), urgent revascularization (7.92% vs.17.4%; RR = 0.47, 95% CI: 0.30 to 0.73, p < 0.001), and CV hospitalization (8.68% vs.11.4%; RR = 0.65, 95% CI: 0.44to 0.96, p = 0.03) compared with culprit only revascularization. All-cause mortality, stroke, major bleeding events, or contrast induced nephropathy were not affected by the revascularization strategy. Conclusion: The findings of this meta-analysis suggest that in patients with STEMI and MVD, complete revascularization is superior to culprit-only PCI in reducing the risk of MACE outcomes, including cardiovascular mortality, without increasing the risk of adverse safety outcomes

Association of statin use and clinical outcomes in heart failure patients: A systematic review and meta-analysis

Background The role of statins in patients with heart failure (HF) of different levels of left ventricular ejection fraction (LVEF) remains unclear especially in the light of the absence of prospective data from randomized controlled trials (RCTs) in non-ischemic HF, and taking into account potential statins’ prosarcopenic effects. We assessed the association of statin use with clinical outcomes in patients with HF. Methods We searched PubMed, EMBASE, Scopus, Google Scholar and Cochrane Central until August 2018 for RCTs and prospective cohorts comparing clinical outcomes with statin vs non-statin use in patients with HF at different LVEF levels. We followed the guidelines of the 2009 PRISMA statement for reporting and applied independent extraction by multiple observers. Meta-analyses of hazard ratios (HRs) of effects of statins on clinical outcomes used generic inverse variance method and random model effects. Clinical outcomes were all-cause mortality, cardiovascular (CV) mortality and CV hospitalization. Results Finally we included 17 studies (n = 88,100; 2 RCTs and 15 cohorts) comparing statin vs non-statin users (mean follow-up 36 months). Compared with non-statin use, statin use was associated with lower risk of all-cause mortality (HR 0.77, 95% confidence interval [CI], 0.72–0.83, P < 0.0001, I2 = 63%), CV mortality (HR 0.82, 95% CI: 0.76–0.88, P < 0.0001, I2 = 63%), and CV hospitalization (HR 0.78, 95% CI: 0.69–0.89, P = 0.0003, I2 = 36%). All-cause mortality was reduced on statin therapy in HF with both EF < 40% and ≥ 40% (HR: 0.77, 95% Cl: 0.68–0.86, P < 0.00001, and HR 0.75, 95% CI: 0.69–0.82, P < 0.00001, respectively). Similarly, CV mortality (HR 0.86, 95% CI: 0.79–0.93, P = 0.0003, and HR 0.83, 95% CI: 0.77–0.90, P < 0.00001, respectively), and CV hospitalizations (HR 0.80 95% CI: 0.64–0.99, P = 0.04 and HR 0.76 95% CI: 0.61–0.93, P = 0.009, respectively) were reduced in these EF subgroups. Significant effects on all clinical outcomes were also found in cohort studies’ analyses; the effect was also larger and significant for lipophilic than hydrophilic statins. Conclusions In conclusion, statins may have a beneficial effect on CV outcomes irrespective of HF etiology and LVEF level. Lipophilic statins seem to be much more favorable for patients with heart failure.Revisión por pare

The impact of type of dietary protein, animal versus vegetable, in modifying cardiometabolic risk factors: A position paper from the International Lipid Expert Panel (ILEP)

Proteins play a crucial role in metabolism, in maintaining fluid and acid-base balance and antibody synthesis. Dietary proteins are important nutrients and are classified into: 1) animal proteins (meat, fish, poultry, eggs and dairy), and, 2) plant proteins (legumes, nuts and soy). Dietary modification is one of the most important lifestyle changes that has been shown to significantly decrease the risk of cardiovascular (CV) disease (CVD) by attenuating related risk factors. The CVD burden is reduced by optimum diet through replacement of unprocessed meat with low saturated fat, animal proteins and plant proteins. In view of the available evidence, it has become acceptable to emphasize the role of optimum nutrition to maintain arterial and CV health. Such healthy diets are thought to increase satiety, facilitate weight loss, and improve CV risk. Different studies have compared the benefits of omnivorous and vegetarian diets. Animal protein related risk has been suggested to be greater with red or processed meat over and above poultry, fish and nuts, which carry a lower risk for CVD. In contrast, others have shown no association of red meat intake with CVD. The aim of this expert opinion recommendation was to elucidate the different impact of animal vs vegetable protein on modifying cardiometabolic risk factors. Many observational and interventional studies confirmed that increasing protein intake, especially plant-based proteins and certain animal-based proteins (poultry, fish, unprocessed red meat low in saturated fats and low-fat dairy products) have a positive effect in modifying cardiometabolic risk factors. Red meat intake correlates with increased CVD risk, mainly because of its non-protein ingredients (saturated fats). However, the way red meat is cooked and preserved matters. Thus, it is recommended to substitute red meat with poultry or fish in order to lower CVD risk. Specific amino acids have favourable results in modifying major risk factors for CVD, such as hypertension. Apart from meat, other animal-source proteins, like those found in dairy products (especially whey protein) are inversely correlated to hypertension, obesity and insulin resistance

One month is not inferior to prolonged dual antiplatelet therapy after PCI with drug-eluting stents: a systematic review and meta-analysis of randomized clinical trials

Aim: The aim of this meta-analysis was to evaluate the safety of 1-month dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) with drug eluting stents (DES), followed by aspirin or a P2Y12 receptor inhibitor based on the available evidence. Methods: PubMed, MEDLINE, Embase, Scopus, Google Scholar, CENTRAL and ClinicalTrials.gov databases search identified 4 RCTs of 27,131 patients who underwent PCI with DES which compared 1-month vs. \u3e1-month DAPT. The primary endpoint was major bleeding and co-primary endpoint stent thrombosis. Secondary endpoints included all-cause mortality, myocardial infarction (MI), stroke and major adverse clinical events (MACE). Results: Compared to \u3e1 month DAPT, the 1 month DAPT was associated with similar rate of major bleeding (OR=0.74, 95%CI: 0.51 to 1.04, p=0.11, I2=67%), stent thrombosis (OR=1.10, 95%CI: 0.82 to 1.47, p=0.53, I2=0.0%), similar risk for all-cause mortality (OR=0.89, 95%CI: 0.77 to 1., p=0.14, I2=0%), CV death (OR=0.80, 95%CI: 0.55 to 1.60, p=0.24, I2=0.0%), MI (OR=1.02, 95%CI: 0.87 to 1.19, p=0.81, I2=0.0%) and stroke (OR=0.76, 95%CI: 0.54 to 1.08, p=0.13, I2=29%). The risk of MACE was lower risk of MACE was lower (OR=0.84, 95%CI: 0.73 to 0.97, p=0.02, I2=36%) in the 1-month DAPT compared to the \u3e1-month DAPT. Only patients with stable CAD had lower risk of MACE with 1-month DAPT (OR=0.81, 95%CI: 0.67 to 0.98, p=0.03, I2=21%) compared to \u3e 1-month DAPT. Conclusion: This meta-analysis proved non-inferiority of 1-month DAPT followed by aspirin or a P2Y12 receptor inhibitor compared to longer term DAPT in patients undergoing PCI with DES

Percutaneous Coronary Intervention Is Not Superior to Optimal Medical Therapy in Chronic Coronary Syndrome: A Meta-Analysis

(1) Background and Aim: Conflicting evidence exists regarding the benefits of percutaneous coronary intervention (PCI) on survival and symptomatic relief of patients with chronic coronary syndrome (CCS) compared with optimal medical therapy (OMT). This meta-analysis is to evaluate the short- and long-term clinical benefit of PCI over and above OMT in CCS. (2) Methods: Main endpoints were major adverse cardiac events (MACEs), all-cause mortality, cardiovascular (CV) mortality, myocardial infarction (MI), urgent revascularization, stroke hospitalization, and quality of life (QoL). Clinical endpoints at very short (≤3 months), short- (n = 8307 and OMT n = 8136) were included in the meta-analysis. At mean follow-up of 27.7 months, the PCI group had similar risk of MACE (18.2 vs. 19.2 %; p p = 0.56), CV mortality (8.74 vs. 9.87%; p = 0.30), MI (7.69 vs. 8.29%; p = 0.32), revascularization (11.2 vs. 18.3%; p = 0.08), stroke (2.18 vs. 1.41%; p = 0.10), and hospitalization for anginal symptoms (13.5 vs. 13.9%; p = 0.69) compared with OMT. These results were similar at short- and long-term follow-up. At the very short-term follow-up, PCI patients had greater improvement in the QoL including physical limitation, angina frequency, stability, and treatment satisfaction (p < 0.05 for all) but such benefits disappeared at the long-term follow-up. (4) Conclusions: PCI treatment of CCS does not provide any long-term clinical benefit compared with OMT. These results should have significant clinical implications in optimizing patient’s selection for PCI treatment

Ventricular septal defect associated with aortic regurgitation and ascending aortic aneurysm : a case report

Introduction: Ventricular septal defect (VSD) is one of the most common congenital cardiac anomalies. Patients with perimembranous VSD may have aortic regurgitation (AR) secondary to prolapse of the aortic cusp. Case presentation: We present a case of 23-year-old White man with VSD, AR and ascending aortic aneurysm. The patient presented to outpatient clinic with weakness and gradual worsening shortness of breath for the past 5 years. Clinical examination revealed regular heart rhythm and loud continuous systolic-diastolic murmur (Lewin’s grade 6/6), heard all over the precordium, associated with a palpable thrill. The ECG showed right axis deviation, fractionated QRS in V1 and signs of biventricular hypertrophy. The chest X-ray showed cardiomegaly. Transthoracic and transesophageal echocardiograms showed a perimembranous VSD with moderate restrictive shunt (Qp/Qs = 1.6), aortic regurgitation (AR), and ascending aortic aneurysm. Other clinical and laboratory findings were within normal limits. Conclusions: Perimembranous VSD, may be associated with aortic regurgitation and ascending aortic aneurysm as secondary phenomenon if it is not early diagnosed and successfully treated

Diagnostic Usefulness of Spiroergometry and Risk Factors of Long COVID in Patients with Normal Left Ventricular Ejection Fraction

The emergence of the Coronavirus Disease 2019 (COVID-19) pandemic has brought forth various clinical manifestations and long-term complications, including a condition known as long COVID. Long COVID refers to a persistent set of symptoms that continue beyond the acute phase of the disease. This study investigated the risk factors and the utility of spiroergometry parameters for diagnosing patients with long COVID symptoms. The 146 patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with normal left ventricular ejection fraction and without respiratory diseases were included and divided into two groups: the group demonstrating long COVID symptoms [n = 44] and the group without long COVID symptoms [n = 102]. The clinical examinations, laboratory test results, echocardiography, non-invasive body mass analysis, and spiroergometry were evaluated. ClinicalTrials.gov Identifier: NCT04828629. Patients with long COVID symptoms had significantly higher age [58 (vs.) 44 years; p p = 0.02)], left atrial diameter (LA) [37 vs. 35 mm; p = 0.04], left ventricular mass index (LVMI) [83 vs. 74 g/m2, p = 0.04], left diastolic filling velocity (A) [69 vs. 64 cm/s, p = 0.01], the ratio of peak velocity of early diastolic transmitral flow to peak velocity of early diastolic mitral annular motion (E/E’) [7.35 vs. 6.05; p = 0.01], and a lower ratio of early to late diastolic transmitral flow velocity (E/A) [1.05 vs. 1.31; p = 0.01] compared to the control group. In cardiopulmonary exercise testing (CPET), long COVID patients presented lower forced vital capacity (FVC) [3.6 vs. 4.3 L; p 2max) [21 vs. 23 mL/min/kg; p = 0.04], respiratory exchange ratio (RER) [1.0 vs. 1.1; p = 0.04], forced expiratory volume in one second (FEV1) [2.90 vs. 3.25 L; p = 0.04], and a higher ratio of forced expiratory volume in one second to forced vital capacity (FEV1/FVC%) [106 vs. 100%; p = 0.0002]. The laboratory results pointed out that patients with long COVID symptoms also had a lower rate of red blood cells (RBC) [4.4 vs. 4.6 × 106/uL; p = 0.01]; a higher level of glucose [92 vs. 90 mg/dL; p = 0.03]; a lower glomerular filtration rate (GFR) estimate by Modification of Diet in Renal Disease (MDRD) [88 vs. 95; p = 0.03]; and a higher level of hypersensitive cardiac Troponin T (hs-cTnT) [6.1 vs. 3.9 pg/mL; p = 0.04]. On the multivariate model, only FEV1/FVC% (OR 6.27, 95% CI: 2.64–14.86; p p < 0.001) in predicting the symptoms of long COVID. Spiroergometry parameters are useful in diagnosing long COVID and differentiating it from cardiovascular disease

Impaired left atrial reservoir function in metabolic syndrome predicts symptoms in HFpEF patients

Background and Aim: The hospital readmission rate has been thought to reflect the quality of patient care. Understanding the risk factors for these can guide strategies to reduce them. Methods This study included 194 consecutive patients (age 62 ± 9 years) with stable HFpEF. LV dimensions, ejection fraction (EF), mitral annulus peak systolic excursion (MAPSE), myocardial velocities (s’, e’ and a’), LA dimensions and volumes were measured. Total LA emptying fraction (LA EF) was measured by Simpson rule volumes. Based on the NCEP-ATP III criteria, patients were divided into two groups; MetS (n=89) and non-MetS (n=105) and were compared with 34 age and gender matched controls. Results Age and gender were not different between patients and control neither between MetS and non-Met. LV dimensions, EF and longitudinal function indices were also not different. The MetS patients had higher LV mass index (p=0.038), lower septal and lateral e’ (p=0.003 and p=0.001, respectively) velocities, larger LA minimal volume (p=0.007) and lower LA EF (p<0.001) compared with the non-MetS patients. Age, LA EF and MetS independently predicted the NYHA class. Conclusions Despite no difference in LV systolic function, patients with HFpEF and MetS have worse LA emptying fraction, compared with HFpEF and non-MetS patients. In addition, LA reservoir function impairment and MetS independently predict patients limiting symptoms, thus add to a better understanding of HFpE
