ABSTRACT
Objectives: This study aimed to evaluate the long-term prognostic value of E/e’ ratio in patients with STsegment elevation myocardial infarction (STEMI). Methods: We retrospectively assessed 314 patients who underwent primary coronary interventions between January 2010 and December 2015. The included patients were classified into two groups according to the E/e’ ratios: E/e’<15 (n ¼ 245) and E/e’15 (n ¼ 69). We investigated the incidence of major adverse cardiac events (MACEs) from the event to the final follow-up period of at least three years. Results: A total of 55 cases of MACEs occurred during the follow-up. The E/e’15 group showed a significantly higher rate of MACEs than the E/e’<15 group (34.8% vs. 12.7%, p < 0.001). Among the MACE, the percentage of cardiac deaths (17.4% vs. 0.4%, p < 0.001) was higher in the E/e’15 group than in the E/ e’<15 group. In the multivariable model, E/e’15 was demonstrated as the strongest prognostic factor for MACEs (hazard ratio [HR], 2.597; 95% confidence interval [CI], 1.294e5.211; p ¼ 0.007) and cardiac death (HR, 27.537; 95% CI, 3.287e230.689; p ¼ 0.002), while left ventricular ejection fraction (LVEF) was not. Neither the discrepancy of systolic nor diastolic function between initial and follow-up echocardiography affected the overall prevalence of MACEs. A disparity was observed between the two groups, with a significant increase in the rate of MACEs in the E/e’15 group (log-rank test, p < 0.001). Conclusion: The baseline E/e’15 in patients with STEMI after successful reperfusion is the strongest predictor of poor long-term clinical outcomes among those analyzed.
ABSTRACT
Objectives: This prospective, randomized study assessed short-term outcomes and safety of ultra-low contrast percutaneous coronary intervention(ULC-PCI) vs conventional PCI in high risk for contrast induced acute kidney injury(CI-AKI) patients presenting with acute coronary syndrome(ACS). Background: Patients at an increased risk of developing CI-AKI can be identified prior to PCI based on their pre-procedural risk scores. ULC-PCI is a novel contrast conservation strategy in such high risk patients for prevention of CI-AKI. Methods: 82 patients undergoing PCI for ACS were enrolled having estimated glomerular filtration rate(eGFR) < 60 ml/min/1.73 m2 and moderate to very high pre-procedural risk of developing CI-AKI as calculated by Maioli risk calculator. They were randomized into two groups of 41 patients each of ULCPCI (contrast volume patient's eGFR) and conventional PCI (contrast volume 3xpatient's eGFR). Primary end point was development of CI-AKI. Results: Baseline clinical and angiographic characteristics were similar between groups. Primary outcome of CI-AKI occurred more in patients of the conventional PCI group [7 (17.1%)] than in the ULC PCI group [(0 patients), p ¼ 0.012]. Contrast volume (41.02 (±9.8) ml vs 112.54 (±25.18) ml; P < 0.0001) was markedly lower in the ULC-PCI group. No significant difference in secondary safety outcomes between two study arms at 30 days. IVUS was used in 17% patients in ULC PCI. Conclusion: ULC-PCI in patients with increased risk of developing CI-AKI is feasible, appears safe, and has the potential to decrease the incidence of CI-AKI specially in resource limited setting such as ours where coronary imaging by IVUS is not possible in every patient.
ABSTRACT
Aims: To evaluate the feasibility of small-bore single laparoscopy-assisted trans-vaginal ovarian cystectomy. Study Designs: A retrospective study was performed through a review of the medical records of women who had undergone laparoscopy-assisted trans-vaginal ovarian cystectomy for benign conditions. Place and Duration of Study: Department of obstetrics & gynecology of Her women’s clinic and Chonnam National University Hospital, Between January 2010 to January 2014. Methodology: 148 women had undergone small-bore (3-5mm) single-port laparoscopy-assisted trans-vaginal ovarian cystectomy for benign adnexal mass. The technique consists of small bore single laparoscopic inspection phase, trans-vaginal operative phase, and laparoscopic checking phase. Age, parity, body mass index (BMI), bilaterality, dimensions of mass, location, total operative time, hemoglobin change, and complications were measured. Results: 148 procedures were successfully completed without the need for extra-umbilical puncture. The mean±SD of total operative time and the largest dimension of the mass were 46.9±21.5min and 6.9±4.1cm, respectively. Spillage of cystic contents was minimal, and if it did occur, it was localized to the posterior cul-de-sac with no related complication. The median decline in the hemoglobin level from before surgery to postoperative day 1 was 1.7±0.8g/dL. The pathologic diagnoses were as follows: dermoid cyst, 82; endometriotic cyst, 31; corpus luteal cyst, 12; serous cystadenoma, 5; mucinous cystadenoma, 9; parovarian or paratubal cyst, 9. The postoperative courses were uneventful in most patients, but four had a transient fever greater than 38ºC and 8 women had small operation site hematoma. All of them recovered following conservative management. Conclusion: We believe that small-bore single laparoscopy-assisted trans-vaginal ovarian cystectomy ensures the advantages of trans-vaginal surgery and the safety of the laparoscope.
