Objective This study was performed to analyze and compare the efficacy of three treatment methods for left ventricular aneurysm (LVA): coronary artery bypass grafting (CABG) combined with left ventricular resection, drug treatment, and percutaneous coronary intervention (PCI). Methods In total, 183 patients with LVA from Fuwai Hospital were divided into three groups according to the treatment method: 51 patients underwent left ventricular resection combined with CABG (CABG-resection group), 65 underwent drug treatment (drug group), and 67 underwent PCI (PCI group). The clinical characteristics and survival rates of the patients were compared among the three groups. Results The patients’ basic data and medical history were analyzed. The postoperative left ventricular end-diastolic dimension (LVEDD) and left ventricular ejection fraction (LVEF) were significantly higher than those before surgery, indicating that the left ventricular function markedly improved after the operation. Conclusion Surgery is recommended as the first treatment option for LVA, and conservative therapy can be considered for selected patients. Although the difference was not statistically significant, CABG with left ventricular resection was associated with a better LVEF and LVEDD and higher survival and non-recurrence rates than PCI or drug treatment.
Objective To investigate what is the most appropriate strategy for patients with ST-segment elevation myocardial infarction (STEMI) aged ≥80 years in China. Methods This cohort study retrospectively enrolled patients with STEMI aged ≥80 years old and grouped them according to the treatment strategy that was used: a conservative treatment strategy or an invasive treatment strategy. Factors associated with whether to perform an invasive intervention, in-hospital death and a good prognosis were investigated using logistic regression analyses. Results A total of 232 patients were enrolled: conservative treatment group ( n = 93) and invasive treatment group ( n = 139). Patients in the invasive treatment group had a better prognosis and lower incidence of adverse events compared with the conservative treatment group. Advanced age, creatinine level and a higher Killip class were inversely correlated with whether to perform an invasive intervention, while the use of beta-receptor-blocking agents was a favourable factor for invasive treatment. Hypertension and a higher Killip class were risk factors for in-hospital death, while the use of beta-receptor-blocking agents and diuretics decreased the risk of in-hospital death. Conclusions An invasive treatment strategy was superior to a conservative treatment strategy in patients with STEMI aged ≥80 years.
Objectives We compared the diagnostic performance of the ultrasonic flow ratio (UFR) and quantitative flow ratio (QFR) for left main coronary artery (LMCA) stenosis. Background Evaluation of LMCA stenosis remains challenging because of its complex pathogenesis and severity. Computing QFR allows rapid determination of fractional flow reserve (FFR) from coronary angiograms. A novel intravascular ultrasound (IVUS)‐based FFR (UFR) allows rapid FFR computation from IVUS images. Neither of the computational approaches required a pressure wire or hyperemia induction. Previous studies have validated the good diagnostic accuracy of QFR and UFR in identifying hemodynamically significant coronary stenosis using FFR as the reference standard. Methods This retrospective observational study enrolled consecutive patients with intermediate‐grade LMCA stenosis who underwent IVUS evaluation. UFR and QFR of all LMCA stenosis patients were assessed, their correlation and agreement were analyzed, and diagnostic performance of UFR in LMCA stenosis was evaluated. Results Eighty‐three paired comparisons between UFR and QFR were obtained. UFR excellently correlated with QFR (r = 0.74, p < 0.01). The Bland‒Altman plot showed good agreement between UFR and QFR (mean differences: 0.01 ± 0.05, p = 0.34). The area under the curve of UFR for identifying physiological LMCA stenosis was 0.97 (95% confidence interval [CI]: 0.93–1.00, p < 0.01). The overall UFR diagnostic accuracy was 0.95 (95% CI: 0.88–0.99). Conclusions UFR showed excellent correlation and good agreement with QFR in LMCA stenosis assessment, indicating that it is highly feasible to use UFR for functional evaluation of LMCA stenosis.
Background: The association between prior percutaneous coronary intervention (PCI) and prognosis after coronary artery bypass grafting (CABG) remains uncertain. We aimed to evaluate the aforementioned association in a meta-analysis. Methods: PubMed, Cochrane’s Library, and Embase databases were searched for potential studies. A random-effects model was used for the meta-analysis. Meta-regression was performed to evaluate the influence of study characteristics on the outcomes. Results: Thirty-six follow-up studies with 308,284 patients were included, and 40,892 (13.3%) patients had prior PCI. Pooled results showed that prior PCI was associated with higher risks of early (in-hospital or within 1 month) all-cause mortality [odds ratio (OR): 1.26, 95% confidence interval (CI): 1.11–1.44, p = 0.003; I2 = 64%] and major adverse cardiovascular events (MACEs; OR: 1.36, 95% CI: 1.12–1.66, p = 0.002, I2 = 79%), but not with late (follow-up durations from 1 to 13 years) mortality (OR: 1.03, 95% CI: 0.95–1.13, p = 0.44, I2 = 46%) or MACEs (OR: 1.03, 95% CI: 0.97–1.09, p = 0.38, I2 = 0%). Meta-regression showed that the study characteristics of patient number, age, sex, diabetic status, and proportion of patients with prior PCI did not affect the outcomes. Sensitivity analyses limited to multivariate studies excluding patients with acute PCI failure showed similar results (early mortality, OR: 1.25, p = 0.003; early MACE, OR: 1.50, p = 0.001; late mortality, OR: 1.03, p = 0.70). Conclusion: The current evidence, mostly from retrospective observational studies, suggests that prior PCI is related to poor early clinical outcomes, but not to late clinical outcomes, after CABG.
Background: This study aims to investigate the gender differences in treatment strategies among non-STsegment elevation myocardial infarction (NSTEMI) patients ≥80 years old in China.Methods: A total of 190 consecutive NSTEMI patients ≥80 years old in Fuwai Hospital were included from 2014 to 2017. These patients were grouped by gender, and sub-grouped by conservative treatment or invasive treatment. The clinical characteristics, medical history, discharge drug used, and prognosis were collected and compared between these two treatment strategies.Results: There were significant differences between these two treatment strategies in terms of GRACE grade, history of myocardial infarction (MI), after coronary artery bypass grafting (CABG), III grade, renal dysfunction, anemia, and use of diuretic (P<0.05). In addition, the age, creatinine and Killip class of female patients, and the death and good prognosis of male patients were found to be significantly different between these two treatment strategies (P<0.05). The multivariate logistic regression analysis revealed that the death of males was significantly associated with treatment strategies in the multivariable logistic regression analysis (P<0.05). In addition, the Kaplan-Meier survival analyses revealed that the survival rates of invasive strategy were significantly higher, when compared to that of conservative strategy in males (P=0.001) and females (P=0.015).Conclusions: There were gender differences in treatment strategies among NSTEMI patients ≥80 years old. The difference in treatment strategies in males was more pronounced than in females, in terms of longterm survival rate.
The present study aimed to explore the clinical characteristics and management of retroperitoneal hematoma (RPH) after invasive intervention during a 12-year period in China. A retrospective review of patients with RPH after various invasive interventions was conducted at the China National Center for Cardiovascular Diseases. A total of 42 patients with a mean age of 63.1±2.5 years were continuously recruited in the study between January 2007 and September 2018. The incidence, manifestations and management of RPH were analyzed. A total of 20 patients had punctures in the femoral arterial access under the inguinal ligament and 5 patients had punctures above the inguinal ligament. The majority of RPH occurred within 24 h after intervention, while some occurred after postoperative 24 h. Pain was the most common symptom in patients with RPH. All patients who underwent intervention presented a reduction in hemoglobin (HB) concentration. The overall incidence of nosocomial infection was 38.1% and mortality was 7.1%. The findings demonstrated that RPH is a rare complication after invasive intervention of cardiovascular diseases with non-specific clinical manifestations. The reduction of HB concentration was a vital manifestation for RPH. Most RPH cases could be treated by conservative treatment and blood transfusion. A puncture in the femoral arterial access under the inguinal ligament may result in RPH.
Postprocedural cardiac troponin I (cTnI) elevation commonly occurs in patients undergoing percutaneous coronary intervention (PCI); however, its prognostic value remains controversial. This study aimed to investigate the prognostic value of peak postprocedural cTnI in cardiac patients with or without three-vessel disease (TVD) undergoing complete PCI. A total of 1237 consecutive patients (77% males, mean age 58 ± 10 years) with normal baseline cTnI levels were enrolled, 439 patients (77% males, 59 ± 10 years) with TVD, and 798 patients (77% males, 57 ± 10 years) with single- or double-vessel disease (non-TVD). The primary outcome was the occurrence of major adverse cardiovascular events (MACE), defined as a composite of non-fatal MI, non-fatal stroke, unplanned revascularization, re-hospitalization due to heart failure or severe arrhythmias, and all-cause death. During the median follow-up of 5.3 years, a total of 169 patients (13.7%) developed MACE, including 73 (16.6%) in the TVD group and 96 (12.0%) in the non-TVD group (p = 0.024). After adjustment, the multivariate Cox analysis showed that hypertension (HR 1.50; 95% CI: 1.01–2.20; p = 0.042), TVD (HR 1.44; 95% CI: 1.03–2.02; p = 0.033), and cTnI ≥ 70× URL (HR 2.47; 95% CI: 1.28–4.78, p = 0.007) were independently associated with increased MACE during long-term follow-up. Further subgroup analyses showed that cTnI ≥ 70× URL was an independent predictor of MACE in TVD patients (HR 3.32, 95% CI: 1.51–7.34, p = 0.003), but not in non-TVD patients (HR 1.01, 95%CI: 0.24–4.32, p = 0.991). In conclusion, elevation of post-PCI cTnI ≥ 70× URL is independently associated with a high risk of MACE during long-term follow-up in patients with TVD, but not in those with non-TVD.
