OBJECTIVE

This study aims to determine the clinical profile and incidence of in-hospital outcomes of patients who underwent coronary artery bypass graft surgery (CABG) under the Philippine Health Insurance Corporation (Philhealth) Z Benefit Package (PZBP).

A retrospective descriptive cohort study. A review of medical records was done from July 2017 to October 2023 to collect data and in-hospital outcomes of patients who underwent CABG surgery under Z benefit package.

One hundred twenty-six patients were included in the study. The mean age of patients was 60 years and majority of them were male and came from NCR. Hypertension was the leading cause of comorbidity. The top two most common in-hospital outcomes were hospital-acquired pneumonia and postoperative atrial fibrillation. Most commonly observed caused of increased length in hospitalization was pneumonia. The mean Society of Thoracic Surgeons (STS) (operative mortality) and Euro scores were 1.04 ± 0.82 and 0.88 ± 0.56, respectively. All patients had successful surgical outcome with no mortality and an average length of stay in the hospital of six days.

This study will serve as a future reference to enhance screening criteria and improved in-hospital outcomes for those who will undergo CABG under Z benefit package. The study also showed insights on clinical profile and in-hospital outcomes of patients who underwent CABG in our own institution and this may give way to a larger scale of study involving multiple centers who also offer the said program.

Objective: To describe the treatment outcomes of patients who underwent coronary artery bypass grafting (CABG) with vein patch angioplasty with internal mammary artery (IMA) grafting of the diffusely diseased left anterior descending (LAD) coronary artery. Methods: This is a retrospective observational study of 26 patients who have undergone vein patch angioplasty of the LAD coronary artery with IMA grafting in three centers by a single surgeon from January 2012 to August 2017. The demographic profile, intraoperative data, and postoperative outcome (including in-hospital mortality and morbidity, perioperative myocardial infarction, and NYHA functional classification) were recorded. Continuous variables were expressed as means with standard deviation and categorical variables summarized as frequencies and percentages. Student’s t-test was used to compare the preoperative versus postoperative mean NYHA functional class. Results: There were 22 (85%) males and 4 (15%) females with a mean age of 62 years (range: 34 to 82). Twentyfive patients (96%) had a three-vessel disease, and one (4%) had a two-vessel disease. Nine patients (35%) had a preoperative myocardial infarction. The mean cardiopulmonary bypass and aortic-cross clamp times were 156 and 118 minutes, respectively. The mean number of vessels grafted was 4.12. Multiple arterial grafting was used in seven patients (27%). There were two in-hospital mortalities (7.7%) and three morbidities (11.5%), including reoperation for bleeding, acute kidney injury, and leg wound infection. Six patients (23%) developed postoperative atrial fibrillation. No patient developed perioperative myocardial infarction. The mean ICU stay was three days, and the mean hospital stay was 10.27 days. The mean NYHA functional class improved from 2.85 preoperatively to 1.5 postoperatively (p<0.00001). Among patients with improvement, postoperative NYHA improved by two functional classes in 38% and by one functional class in 62%. Conclusion Vein patch angioplasty is a valuable technique for diffuse coronary stenosis of the LAD artery with acceptable early results.

OBJECTIVE: To evaluate the feasibility and safety of Liuzijue exercise (LE) for the clinical effect in patients after cardiac surgery. METHODS: Totally 120 patients who underwent cardiac surgery and were admitted to the Cardiothoracic Intensive Care Unit of Nanjing Drum Tower Hospital between July and Oclober, 2022 were allocated to the LE group, the conventional respiratory training (CRT) group, and the control group by a random number table at a ratio of 1:1:1; 40 patients in each group. All patients received routine treatment and cardiac rehabilitation. LE group and CRT group respectively performed LE and CRT once a day for 30 min for 7 days. Control group did not receive specialized respiratory training. The forced vital capacity, forced expiratory volume in 1 s, peak inspiratory flow rate, peak expiratory flow rate, maximum inspiratory pressure, maximum expiratory pressure, modified Barthel index (MBI), and Hamilton Rating Scale for Anxiety (HAM-A) were evaluated before, after 3 and 7 days of intervention. In addition, the postoperative length of hospital stay (LOS) and the adverse events that occurred during the intervention period were compared. RESULTS: A total of 107 patients completed the study, 120 patients were included in the analysis. After 3 days of intervention, the pulmonary function, respiratory muscle strength, MBI and HAM-A of all 3 groups improved compared with that before the intervention (P<0.05 or P<0.01). Compared with the control group, pulmonary function and respiratory muscle strength were significantly improved in the CRT and LE groups (P<0.05 or P<0.01). MBI and HAM-A were significantly improved in the LE group compared with the control and CRT groups (P<0.05 or P<0.01). On the 7th day after intervention, the difference was still statistically significant (P<0.01), and was significantly different from that on the 3rd day (P<0.05 or P<0.01). In addition, on the 7th day of intervention, the pulmonary function and respiratory muscle strength in the LE group were significantly improved compared with those in the CRT group (P<0.01). MBI and HAM-A were significantly improved in the CRT group compared with the control group (P<0.01). There were no significant differences in postoperative LOS among the 3 groups (P>0.05). No training-related adverse events occurred during the intervention period. CONCLUSIONS LE is safe and feasible for improving pulmonary function, respiratory muscle strength, the ability to complete activities of daily living and for relieving anxiety of patients after cardiac surgery (Registration No. ChiCTR2200062964).

In this study, we aim to elucidate the clinical impact and long-term course of tricuspid regurgitation (TR), taking into account its dynamic nature, after biatrial orthotopic heart transplant (OHT). All consecutive adult patients undergoing biatrial OHT (1984-2017) with an available follow-up echocardiogram were included. Mixed-models were used to model the evolution of TR. The mixed-model was inserted into a Cox model in order to address the association of the dynamic TR with mortality. In total, 572 patients were included (median age: 50 years, males: 74.9%). Approximately 32% of patients had moderate-to-severe TR immediately after surgery. However, this declined to 11% on 5 years and 9% on 10 years after surgery, adjusted for survival bias. Pre-implant mechanical support was associated with less TR during follow-up, whereas concurrent LV dysfunction was significantly associated with more TR during follow-up. Survival at 1, 5, 10, 20 years was 97% ± 1%, 88% ± 1%, 66% ± 2% and 23% ± 2%, respectively. The presence of moderate-to-severe TR during follow-up was associated with higher mortality (HR: 1.07, 95% CI (1.02-1.12), p = 0.006). The course of TR was positively correlated with the course of creatinine (R = 0.45). TR during follow-up is significantly associated with higher mortality and worse renal function. Nevertheless, probability of TR is the highest immediately after OHT and decreases thereafter. Therefore, it may be reasonable to refrain from surgical intervention for TR during earlier phase after OHT.

Compared with conventional cardiopulmonary resuscitation (CCPR), extracorporeal cardiopulmonary resuscitation (ECPR) can improve the survival rate of patients with cardiac arrest, and reduce the risk of reperfusion injury. However, it is still difficult to avoid the risk of secondary brain damage. Low temperature management has good neuroprotective potential for ECPR patients, which minimizes brain damage. However, unlike CCPR, ECPR has no clear prognostic indicator. The relationship between ECPR combined with hypothermia management-related treatment measure and neurological prognosis is not clear. This article reviews the effect of ECPR combined with different therapeutic hypothermia on brain protection and provides a reference for the prevention and treatment of neurological injury in patients with ECPR.

OBJECTIVE: To summarize the application experience and clinical effect of radial artery in total arterial coronary revascularization (TAR) in elderly patients. METHODS: Retrospectively analyzed the clinical data of patients who underwent TAR at the University of Hong Kong Shenzhen Hospital from July 1, 2020 to May 30, 2022. Patients were divided into ≥ 65-year-old group and < 65-year-old group according to age. The radial artery blood flow, diameter, intimal integrity and Allen test were evaluated by ultrasound before operation. The distal ends of radial artery were collected for pathological examination during operation. Coronary artery CT angiography (CTA) was examined postoperatively and follow up. The safety and reliability of ultrasonic assessment of radial artery and application of radial artery in elderly patients with TAR were summarized and analyzed. RESULTS: A total of 101 patients received TAR, including 35 cases aged ≥ 65 years old, 66 cases aged < 65 years old; 78 cases used bilateral radial arteries, and 23 cases used unilateral radial arteries. 4 cases of bilateral internal mammary arteries. All the proximal ends of the radial artery were anastomosed to the proximal end of the ascending aorta, 34 cases were performed of "Y" grafts, and 4 cases were sequential anastomoses. There was no in-hospital death and perioperative cardiovascular events. Perioperative cerebral infarction occurred in 3 patients. 1 patients was reoperated for bleeding. Intra-aortic balloon pump (IABP) assistance was used in 21 patients. Poor wound healing occurred in 2 cases and healed well after debridement. Follow-up of 2 to 20 months after discharge showed no internal mammary artery occlusion and 4 radial artery occlusions; no major adverse cardiovascular and cerebrovascular event (MACCE) occurred, and the survival rate was 100%. There was no significant difference in the above perioperative complications and follow-up endpoints between the two age groups. CONCLUSIONS By adjusting the order of bypass anastomosis and optimizing the preoperative evaluation method, radial artery combined with internal mammary artery can obtain better outcome early in TAR, and can be safely and reliably applied to elderly patients.

Targeted temperature management (TTM) has been partially applied in patients with restoration of spontaneous circulation (ROSC) after cardiac arrest (CA). In the 2020 American Heart Association (AHA) cardiopulmonary resuscitation (CPR) guidelines, TTM is used as advanced life support after ROSC for the treatment of patients with CPR. TTM has a protective effect on cardiac function after CA, but the specific mechanism of its protective effect on cardiac function remains unclear. In this paper, the basic experimental progress, clinical trial progress and development prospect of TTM on the protective mechanism of cardiac function after CA are reviewed.

Objective: To evaluate the predictive value of the proportion of hibernating myocardium (HM) in total perfusion defect (TPD) on reverse left ventricle remodeling (RR) after coronary artery bypass graft (CABG) in patients with heart failure with reduced ejection fraction (HFrEF) by ^99mTc-methoxyisobutylisonitrile (MIBI) single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) combined with ¹⁸F-flurodeoxyglucose (FDG) gated myocardial imaging positron emission computed tomography (PET). Methods: Inpatients diagnosed with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2016 to January 2022 were prospectively recruited. MPI combined with ¹⁸F-FDG gated PET was performed before surgery for viability assessment and the patients received follow-up MPI and ¹⁸F-FDG gated PET at different stages (3-12 months) after surgery. Δ indicated changes (post-pre). Left ventricular end-systolic volume (ESV) reduced at least 10% was defined as RR, patients were divided into reverse remodeling (RR+) group and the non-reverse group (RR-). Binary logistic regression analysis was used to identify predictors of RR. Receiver operating characteristic (ROC) curve analysis was performed and the area under the curve (AUC) was calculated to assess the cut-off value for predicting RR. Additionally, we retrospectively enrolled inpatients with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2021 to January 2022 as the validation group, who underwent MPI and ¹⁸F-FDG gated PET before surgery. Echocardiography was performed before CABG and after CABG (3-12 months). In the validation group, the reliability of obtaining the cut-off value for the ROC curve was verified. Results: A total of 28 patients with HFrEF (26 males; age (56.9±8.7) years) were included in the prospective cohort. HM/TPD was significantly higher in the RR+ group than in the RR- group ((51.8%±17.9%) vs. (35.7%±13.9%), P=0.016). Binary logistic regression analysis revealed that HM/TPD was an independent predictor of RR (Odds ratio=1.073, 95% Confidence interval: 1.005-1.145, P=0.035). ROC curve analysis revealed that HM/TPD=38.3% yielded the highest sensitivity, specificity, and accuracy (all 75%) for predicting RR and the AUC was 0.786 (P=0.011). Meanwhile, a total of 100 patients with HFrEF (90 males; age (59.7±9.6) years) were included in the validation group. In the validation group, HM/TPD=38.3% predicted RR in HFrEF patients after CABG with the highest sensitivity, specificity and accuracy (82%, 60% and 73% respectively). Compared with the HFrEF patients in the HM/TPD<38.3% group (n=36), RR and cardiac function improved more significantly in the HM/TPD≥38.3% group (n=64) (all P<0.05). Conclusions: Preoperative HM/TPD ratio is an independent factor for predicting RR in patients with HFrEF after CABG, and HM/TPD≥38.3% can accurately predict RR and the improvement of cardiac function after CABG.
