RESUMO
BACKGROUND: Obesity is associated with metabolic syndrome which increases further risk of coronary artery disease and adverse cardiovascular events. Impact of body mass index (BMI) on long-term outcome in patients with coronary chronic total occlusion (CTO) is less clear. METHOD AND RESULTS: From January 2005 to November 2020, a total of 1301 patients with coronary angiographic confirmed CTO were enrolled in our study. Patients were divided into two groups: low BMI group: 18-24.99 kg/m2 and high BMI group ≥25 kg/m2 . Clinical outcomes were 3-year all-cause mortality, 3-year cardiovascular mortality and 3-year non-fatal myocardial infarct. During the 3-year follow-up period, all-cause mortality was significantly higher in patients with low BMI group compared to those in high BMI groups (14% vs. 6%, p = .0001). Kaplan-Meier analysis showed patients with high BMI groups had significant better survival compared with those in low BMI group (p = .0001). In multivariate analysis, higher BMI was independently associated with decreased risk of 3-year all-cause mortality (Hazard ratio [HR]: 0.534; 95% confidence interval [CI]: 0.349-0.819, p = .004) after controlling for age, renal function, prior history of stroke, coronary artery bypass graft, co-morbidities with peripheral arterial disease, heart failure and revascularization status for CTO. In propensity-matched multivariate analysis, high BMI remained a significant predictor of 3-year all-cause mortality (HR, 0.525; 95% CI, 0.346-0.795, p = .002). CONCLUSION: Higher BMI was associated with better long-term outcome in patients with coronary CTO.

BACKGROUND AND AIMS: Nonalcoholic fatty liver disease (NAFLD) is commonly observed in patients with cardiovascular disease (CVD). However, whether the steatosis severity of NAFLD is independently associated with coronary artery atherosclerosis is still controversial. METHODS: Consecutive Taiwanese individuals (1502) who received coronary computed tomography angiography (CCTA) and abdominal sonography as part of a general routine health evaluation were enrolled. The association between steatosis severity, coronary atherosclerosis involvement and various plaque patterns were analysed. RESULTS: Compared with non-steatosis, NAFLD subjects had more cardiovascular risk factors that correlated with the severity of steatosis (P for the trend <.05). The presence of atherosclerotic plaques correlated with the severity of steatosis (none: 53%, mild: 64.1%, and moderate to severe: 66.9%; P for the trend <.001). Parameters of coronary atherosclerosis, including atheroma burden obstructive score (ABOS), segment involvement score (SIS) and segment stenosis score (SSS), were higher in the moderate to severe steatosis group. After adjusting for major confounding factors, the severity of steatosis still correlated with the mixed plaque pattern (P = .043). Subgroup analysis of the risk of the presence of overall coronary and mixed plaques showed a significant association with increasing severity of steatosis, especially among these who were <65 years old, male, without metabolic syndrome, and with lower low-density lipoprotein choleseterol values. CONCLUSION: In this general population, steatosis severity of NAFLD is associated with coronary artery atherosclerosis burden. Furthermore, steatosis severity correlated with the risk of the presence of coronary plaques, especially high-risk plaques, and was independent of traditional risk factors.

BACKGROUND: This study examines the predictive value of a novel systemic immune-inflammation index (SII, platelet × neutrophil/lymphocyte ratio) in coronary artery disease (CAD) patients. METHODS: A total of 5602 CAD patients who had undergone a percutaneous coronary intervention (PCI) were enrolled. They were divided into two groups by baseline SII score (high SII vs low SII) to analyse the relationship between SII groups and the long-term outcome. The primary outcomes were major cardiovascular events (MACE) which includes nonfatal myocardial infarction (MI), nonfatal stroke and cardiac death. Secondary outcomes included a composite of MACE and hospitalization for congestive heart failure. RESULTS: An optimal SII cut-off point of 694.3 × 109 was identified for MACE in the CAD training cohort (n = 373) and then verified in the second larger CAD cohort (n = 5602). Univariate and multivariate analyses showed that a higher SII score (≥694.3) was independently associated with increased risk of developing cardiac death (HR: 2.02; 95% CI: 1.43-2.86), nonfatal MI (HR: 1.42; 95% CI: 1.09-1.85), nonfatal stroke (HR: 1.96; 95% CI: 1.28-2.99), MACE (HR: 1.65; 95% CI: 1.36-2.01) and total major events (HR: 1.53; 95% CI: 1.32-1.77). In addition, the SII significantly improved risk stratification of MI, cardiac death, heart failure, MACE and total major events than conventional risk factors in CAD patients by the significant increase in the C-index (P < .001) and reclassification risk categories by significant NRI (P < .05) and IDI (P < .05). CONCLUSIONS: SII had a better prediction of major cardiovascular events than traditional risk factors in CAD patients after coronary intervention.

BACKGROUND/PURPOSE: Although the lung function test has played an important role in respiratory care for a long time, valid spirometry reference values in the Chinese population in Taiwan remain to be elucidated. METHODS: 2963 healthy Taiwanese subjects aged 21 to 88 years (1765 males, 59.6%) from February 2015 to February 2017 were enrolled. The subjects attempted to meet the 2005 American Thoracic Society (ATS) and the European Respiratory Society (ERS) guidelines when performing forced expiratory spirograms. We would like to establish the spirometry predictive equations for forced expiratory volume (FEV1), forced vital capacity (FVC), FEV1/FVC, and lower limit of normal (LLN) in Taiwan and compare with other Asian populations. RESULTS: We established the spirometry predictive equations using a linear model for the entire population, using age and height as independent variables, which best predicted all spirometry parameters for sea level and highland subjects. We found that the values of FEV1 and FVC for the Taiwanese subjects in our study were systematically lower than those reported in South Korea, Japan, and China, but higher than the values in Yang's 1993 and Pan's 1997 Taiwan study. CONCLUSION: This study addressed the up-to-date spirometry reference equations and values for a healthy adult Chinese population in Taiwan.

BACKGROUND: Current evidence supports the beneficial effect of physical activity in reducing adverse events, however studies on Asian populations are limited and have reported inconsistent findings. The aim of this study was to investigate the association between physical activity and the development of cardiovascular disease, diabetes, hypertension and malignancy in a large Asian cohort. We also investigated interactions between the intensity of physical activity, environmental exposure and biochemical markers. METHODS: Subjects who received annual checkups at Taipei Veterans General Hospital were invited to join this study. Information on physical activity was evaluated using the International Physical Activity Questionnaire Short Form (IPAQ-SF). Associations between the occurrence of clinical events including cardiovascular events, diabetes and malignancies and the intensity of physical activity, biochemical markers, imaging findings, personality trait evaluations and nutrition were evaluated. RESULTS: In the initial stage of this study, a total of 1010 patients enrolled, 626 (62%) were male, 74 (7.4%) had diabetes, 183 (18.3%) had hypertension, and 220 (21.8%) were smokers. The total cholesterol was 202.1 ± 36.2 mg/dL and low-density lipoprotein-cholesterol was 125.7 ± 32.9 mg/dL, including 49.3 ± 13.1 mg/dL for serum high-density lipoprotein-cholesterol and 120.7 ± 70.7 mg/dL for triglycerides. The fasting glucose level was 93.8 ± 21.9 mg/dL, and HbA1c was 5.7 ± 0.7%. All information collected will be incorporated with future events to analyze the relationship between biochemical parameters, physical activity and future adverse events. CONCLUSIONS: These findings will contribute to the understanding of the value of physical activity in determining future cardiovascular and non-cardiovascular events in Asian populations.
RESUMO
OBJECTIVES: The purpose of this study was to assess the long-term clinical impact of revascularization of coronary concomitant coronary chronic total occlusion (CTO) in patients with Non-ST-segment elevation myocardial infarction (NSTEMI). BACKGROUND: CTO is associated with poorer prognosis in patients with NSTEMI. The evidence of revascularization of CTO in patients with NSTEMI is still conflicting. METHODS: Consecutive patients with NSTEMI and CTO who underwent percutaneous coronary intervention (PCI) within 72 h of admission from 2006 to 2015 were retrospectively recruited and analyzed. A total of 967 patients underwent PCI for NSTEMI. Among them, 106 (11%) patients had concomitant CTO and were recruited for analysis. CTO lesions were revascularized successfully in 67 (63.2%) patients (successful CTO PCI group), while the CTO in the remaining 39 patients were either not attempted or failed (No/failed CTO PCI group). RESULTS: The 30-day cardiac death and major adverse cardiac events (MACE) were significantly lower in the successful CTO PCI group (both cardiac death and MACE were 3% vs 30%, P < 0.001, respectively). A landmark analysis set at 30th day for 30-day survivals was performed. After a mean of 2.5-year follow-up, the long-term cardiac death was still significantly lower (16.9% vs 42.3%, P < 0.001), whereas the MACE showed a trend toward lower incidence (26.2% vs 40.7%, P = 0.051) in the successful CTO PCI group. In multivariate Cox regression analysis, successful revascularization of CTO is an independent protective predictor for long-term cardiac death (HR 0.310, 95% CI, 0.109-0.881, P = 0.028) in all population and in propensity-score matched cohort (P = 0.007). CONCLUSIONS: Successful revascularization of CTO was associated with reduced risk of long-term cardiac death in patients with NSTEMI and concomitant CTO.

BACKGROUND: Soluble receptor for advanced glycation end-products (sRAGE) and advanced glycation end-products (AGE) have been associated with risks of cardiovascular disease. Because sRAGE is regarded as a scavenger to AGE, we hypothesized that the ratio of AGE to sRAGE (AGE/sRAGE) is associated with albuminuria in hypertensive patients. METHODS: In this cross-sectional study, a total of 104 patients with essential hypertension were recruited. Hypertension was defined as a systolic blood pressure ≥ 140 mmHg, a diastolic blood pressure ≥ 90 mmHg, or use of antihypertensive treatment. Albuminuria was defined as albumin excretion rate ⧠20 µg/min. Multivariate logistic regression analyses were performed to evaluate the association between AGE/sRAGE and albuminuria. RESULTS: Among the 104 patients, 30 (28.8%) patients had albuminuria and 74 (71.2%) patients did not. Patients with albuminuria had higher AGE (2.15 vs. 1.71 µg/mL), lower sRAGE (424.5 vs. 492.5 pg/ml) and higher AGE/sRAGE (3.79 vs. 3.29 µg/pg) than those without albuminuria. Multivariate logistic regression model revealed that AGE/sRAGE (OR = 1.131, 95% CI = 1.001-1.278, P = 0.048) was independently associated with albuminuria. There was no significant relationship between AGE and sRAGE alone with albuminuria. CONCLUSION: This study suggests that the ratio of AGE to sRAGE may be a surrogate biomarker for microvascular injury. Further prospective studies of the prognostic value of the ratio in relation to microvasular injury are needed.

BACKGROUND: Little is known about the long-term prognostic values of both thrombolysis in myocardial infarction (TIMI) and Global Registry of Acute Cardiac Events (GRACE) risk scores (RSs) to the Asian ethnicity. The purpose of this study is to compare the usefulness of these two scores in risk stratification and prediction of long-term (up to 3 years) outcomes for Chinese patients with myocardial infarction (MI). METHODS: We calculated the TIMI and GRACE RSs for 726 consecutive patients with MI [55.6% with ST-segment elevation (STEMI) and 44.4% with non-ST-segment elevation (NSTEMI)]. RESULTS: Although the risk profile of our population (median TIMI score = 5 for STEMI, 4 for NSTEMI, and median GRACE score = 164) was higher, the in-hospital mortality (7.1% for NSTEMI and 6.7% for STEMI) was comparable to that predicted by GRACE RS. The GRACE RS worked well in predicting short-term and long-term death (C-statistics range 0.710 to 0.789) and triple (death, MI, and stroke) endpoints (C-statistics range 0.695 to 0.764) in both subsets of MI. GRACE RS performed significantly better than the TIMIRS in predicting 3-year mortality in NSTEMI (p = 0.035) and 1-year and 3-year mortality in STEMI (p = 0.028 and 0.009, respectively). Stratification by tertiles of GRACERS furnished greater prognostic information versus risk assessment by the TIMI RS. CONCLUSIONS: The use of RSs revealed a fair to good discriminatory accuracy in predicting both short-term and long-term major adverse cardiac events in Asian patients with MI. Compared with the simpler TIMI RS, the GRACERS was more accurate in predicting long-term mortality.
RESUMO
BACKGROUND: To date, it remains unsettled whether aortic arch calcification (AAC) has prognostic value in patients with acute coronary syndrome. METHODS: From January 1 to December 31, 2013, a total of 225 patients with acute coronary syndrome (mean age 72 ± 26 years, 75% male) were enrolled in this study. Patients admitted to the coronary care unit of a tertiary referral medical center under the preliminary diagnosis of acute coronary syndrome were retrospectively investigated. The primary endpoint was composite of long-term major adverse cardiovascular events. The secondary endpoints were 30-day and long-term all-cause mortality. RESULTS: Of the 225 patients enrolled in this study, 143 had detectable AAC. Those who had AAC were older, with higher Killip classification and thrombolysis in myocardial infarction (TIMI) score with a lower probability of single vessel disease. Acute coronary syndrome patients with AAC had significantly higher 30-day mortality (17.3% vs. 7.1%, log-rank p = 0.02). During a mean follow-up period of 165 ± 140 days (maximum 492 days), the calcification group had significantly increased cardiovascular deaths (27.6% vs. 11.2%, log-rank p = 0.002), all-cause mortality (28.3% vs. 11.2%, log-rank p = 0.001) and composite endpoint of major adverse cardiovascular events (39.4% vs. 24.6%, log-rank p = 0.01). After adjusting for age, gender, diabetes mellitus and hypertension, AAC was an independent risk factor for primary and secondary endpoints among patients with acute coronary syndrome. CONCLUSIONS: AAC provided valuable prognostic information on clinical outcomes in patients with acute coronary syndrome. However, different treatment strategies would be warranted for optimal risk reduction in such a population.
RESUMO
BACKGROUND/PURPOSE: To investigate the correlation between the CHADS2 score and risk of contrast-induced nephropathy (CIN), we conducted a retrospective study in patients who underwent elective percutaneous coronary intervention (PCI) and compared its accuracy with previous scoring systems. METHODS: A total of 539 patients who underwent elective PCI were enrolled. Based on their underlying diseases, such as hypertension, diabetes, and kidney disease, CHADS2 score, R2CHADS2 score, and Mehran's risk score were calculated for each patient. Incidence of CIN was defined as a rise in serum creatinine >0.5 mg/dL or >25% increase in baseline within 48 hours after PCI. All study participants were followed up until October 2014, or until the occurrence of major adverse cardiovascular events (MACEs). RESULTS: Overall, 55 cases (10.2%) of CIN and 90 cases (16.7%) of MACEs were identified after participants were followed up for 1.57 ± 1.46 years. The study cohort was divided into three groups according to CHADS2 scores: score 0, score 1-2, and score 3-6. In multivariate analysis, an increase of 1 point in the CHADS2 score was independently associated with a 37% increase in the risk of CIN (odds ratio, 1.37; 95% confidence interval, 1.00-1.87; p = 0.048) and a 49% increase in MACEs (hazard ratio, 1.49; 95% confidence interval, 1.18-1.88, p = 0.001). In pairwise comparison, the discriminatory performance of CHADS2 score was not inferior to either R2CHADS2 score (p = 0.226) or Mehran's risk score (p = 0.075). CONCLUSION: CHADS2 score could be a simple and useful predictor for CIN in patients undergoing elective PCI.

BACKGROUND: Bilirubin has emerged as an important endogenous antioxidant molecule, and increasing evidence shows that bilirubin may protect against atherosclerosis. The SYNTAX score has been developed to assess the severity and complexity of coronary artery disease. The aim of this study was to evaluate whether serum bilirubin levels are associated with SYNTAX scores and whether they could be used to predict future cardiovascular events in patients undergoing coronary intervention. METHODS: Serum bilirubin levels and other blood parameters in patients with at least 12-h fasting states were determined. The primary endpoint was any composite cardiovascular event within 1 year, including death, nonfatal myocardial infarction, and target-vessel revascularization. RESULTS: In total, 250 consecutive patients with stable coronary artery disease (mean age 70 ± 13) who had received coronary intervention were enrolled. All study subjects were divided into two groups: group 1 was defined as high SYNTAX score (> 22), and group 2 was defined as low SYNTAX score (≤ 22). Total bilirubin levels were significantly lower in the high SYNTAX score group than in the low SYNTAX score group (0.51 ± 0.22 vs. 0.72 ± 0.29 mg/dl, p < 0.001). By multivariate analysis, serum total bilirubin levels were identified as an independent predictor for high SYNTAX score (adjusted odds ratio: 0.28, 95% confidence interval 0.04-0.42; p = 0.004). Use of the Kaplan-Meier analysis demonstrated a significant difference in 1-year cardiovascular events between high (> 0.8 mg/dl), medium (> 0.5, ≤ 0.8 mg/dl), and low (≤ 0.5 mg/dl) bilirubin levels (log-rank test p = 0.011). CONCLUSIONS: Serum bilirubin level is associated with SYNTAX score and predicts future cardiovascular events in patients undergoing coronary intervention.
RESUMO
INTRODUCTION: The DESyne novolimus-eluting coronary stent (NES) is a new-generation drug-eluting stent (DES) that is widely used, but clinical data are rarely reported for this stent. We compared the safety and effectiveness of the DESyne NES and the Orsiro bioresorbable polymer sirolimus-eluting stent (SES) in patients undergoing percutaneous coronary intervention (PCI). METHODS: This was a retrospective, single-center, observational study. Between July 2017 and December 2022, patients who presented with chronic or acute coronary syndrome undergoing PCI with DESyne NES or Orsiro SES were consecutively enrolled in the present study. The primary endpoint, major adverse cardiovascular event (MACE), was a composite of cardiovascular death, target-vessel myocardial infarction, or clinically driven target-lesion revascularization. RESULTS: A total of 776 patients (age 68.8 ± 12.2; 75.9% male) undergoing PCI were included. Overall, 231 patients with 313 lesions received NES and 545 patients with 846 lesions received SES. During a follow-up duration of 784 ± 522 days, the primary endpoint occurred in 10 patients (4.3%) in the NES group and in 36 patients (6.6%) in the SES group. After multivariate adjustment, the risk of MACE did not significantly differ between groups (NES vs. SES, hazard ratio 0.74, 95% CI, 0.35-1.55, p = 0.425). The event rate of individual components of the primary endpoint was comparable between the two groups. CONCLUSIONS: Favorable and similar clinical outcomes were observed in patients undergoing PCI with either NES or SES in a medium-term follow-up duration. Future studies with adequately powered clinical endpoints are required for further evaluation.

BACKGROUND: The benefit of utilizing an invasive strategy in elderly Chinese patients with non-ST-elevation myocardial infarction (NSTEMI) remains unclear. The aim of this study was to determine whether in-hospital revascularization is associated with long-term prognosis in elderly Chinese patients with NSTEMI, as compared with younger patients. METHODS: All patients were followed up for at least 3 years or until the occurrence of a major event. The primary endpoint was all-cause mortality, and the secondary endpoint was the combined occurrence of major adverse cardiovascular events (MACE), including death, nonfatal MI, and ischemic stroke. RESULTS: A total of 343 consecutive NSTEMI patients (148 over the age of 75 years and 195 aged < 75 years) were enrolled. Coronary angiography was performed less frequently in elderly patients (66% vs. 76%; p = 0.027). Multiple logistic regression analysis confirmed the benefit of in-hospital revascularization in the elderly and younger patients, with a statistically significant reduction in the odds of all-cause death and MACE at 1 year and 3 years, respectively. In a multivariable Cox regression analysis, in-hospital revascularization was an independent predictor of future MACE not only in elderly patients [hazard ratio (HR), 0.61; 95% confidence interval (CI), 0.38-0.97] but also in younger patients as well (HR, 0.51; 95% CI, 0.31-0.84). CONCLUSIONS: In Chinese patients with NSTEMI, in-hospital revascularization was associated with significant benefits at 1 year and 3 years in both younger and elderly groups. These results are consistent with the published literature and suggest that advanced age alone should not be regarded as a contraindication to invasive management following presentation with NSTEMI. KEY WORDS: Elderly; Invasive strategy; Myocardial infarction.
RESUMO
Asymmetric dimethylarginine (ADMA) is considered to be an atherogenic molecule. We aimed to investigate the relationship between ADMA and plaque vulnerability assessed by optical coherence tomography (OCT) in patients with stable coronary artery disease (CAD). Two hundred and forty-five patients with stable CAD undergoing OCT-guided percutaneous coronary intervention were included in this study and were divided into two groups according to their ADMA levels. Micro-vessel, macrophage accumulation, thin-cap fibroatheroma, intra-plaque calcium and lipid core content, and vulnerable score (VS) were evaluated by OCT analysis. The patients with higher ADMA levels had significantly higher calcium and lipid content (p < 0.001, respectively). There were significantly more micro-vessel and macrophage (32.8%, p = 0.004 and 52.5%, p < 0.001, respectively) and higher VS (87.7 ± 17.6, p < 0.001) in the higher ADMA group. Moreover, plasma ADMA level was significantly correlated with the intra-plaque lipid, calcium content and VS (p < 0.001, respectively). Plasma ADMA level was identified as an independent predictor of future adverse cardiovascular events, following OCT-guided PCI. In patients with stable CAD, higher plasma ADMA levels were significantly associated with the presence of intra-plaque lipid, calcification, vulnerable plaque, and poor long-term outcomes.

BACKGROUND: Women usually have higher risk after receiving percutaneous coronary interventions (PCIs) than men with coronary artery disease (CAD). The aim of this study was to investigate the association of sex differences with future outcomes in CAD patients undergoing PCI, to assess the role of age, and to extend observed endpoints to stroke and congestive heart failure. METHODS: Six thousand six hundred forty-seven patients with CAD who received successful PCIs. The associations between clinic outcomes and sex were analyzed. The primary outcome was major cardiovascular events (MACE), including cardiac death, nonfatal myocardial infraction, and nonfatal stroke. The secondary outcome was MACE and hospitalization for heart failure (total CV events). RESULTS: During a mean of 52.7 months of follow-up, 4833 men and 1614 women received PCI. Univariate and multivariate analyses showed that women were independently associated with an increased risk of cardiac death (HR, 1.78; 95% CI, 1.32-2.41), hospitalization for heart failure (HR, 1.53; 95% CI, 1.23-1.89), MACE (HR, 1.34; 95% CI, 1.10-1.63), and total CV events (HR, 1.39; 95% CI, 1.20-1.62). In the subgroup analysis, women aged under 60 years had higher cardiovascular risks than men of the same age category. CONCLUSION: Women with CAD after successful PCI had poorer cardiovascular outcomes than men. Additionally, younger women (aged <60 years) were especially associated with a higher risk of developing future adverse cardiovascular outcomes.

OBJECTIVES: The aim of this study was to determine the impact of in-hospital revascularization on different genders and to compare the gender difference in short- and long-term prognosis of Chinese patients with non-ST-elevation myocardial infarction (NSTEMI). BACKGROUND: The benefit of invasive strategy between the genders of Asian ethnic populations with NSTEMI remains unclear. METHODS: A total of 343 consecutive NSTEMI patients were enrolled, 104 (30%) of them were women. All patients were followed up for at least 3 years or until the occurrence of a major event. The primary end point was all-cause death. The secondary end point was the combined occurrence of death or myocardial (re-)infarction (MI). RESULTS: The adjusted in-hospital and long-term clinical outcomes were similar between men and women. However, in-hospital revascularization significantly reduced long-term mortality and composite endpoint in men (P < 0.001), but not in women. After risk stratification by GRACE score, there was favorable effect of invasive strategy in high-risk women. In a multivariate Cox regression analysis, GRACE score (hazard ratio; HR, 1.017; P < 0.001) and in-hospital revascularization (HR, 0.516; P = 0.008) were the independent predictors of death or MI in men. However, only GRACE score was the independent predictor of composite endpoint in women (HR, 1.012; P = 0.004). CONCLUSIONS: In Asian ethnic patients with NSTEMI, the in-hospital and long-term prognosis were similar between men and women. In-hospital revascularization has a benefit in men and high-risk women for reducing the all-cause death at 1 and 3 years.

OBJECTIVES: We aimed to assess the prognostic values of the EuroSCORE, SYNTAX score, and the novel Clinical SYNTAX score (CSS) for 30-day and 1-year outcomes in patients undergoing left main (LM) percutaneous coronary intervention (PCI). BACKGROUND: PCI has become an alternative treatment for LM coronary artery disease, and risk scoring system might be beneficial for pre-PCI risk stratification. METHODS AND RESULTS: We enrolled 198 consecutive patients with unprotected LM disease undergoing PCI (mean age 71.5 ± 10.7 years). The CSS was calculated by multiplying the SYNTAX Score to (age/left ventricular ejection fraction +1 for each 10 mL the estimated glomerular filtration rate <60 mL/min per 1.73 m(2)). The endpoints were 30-day, and 1-year all-cause death and major adverse cardiovascular events (MACE), which were defined as all-cause death, nonfatal MI, and clinical-driven target vessel revascularization. Comparing with the SYNTAX score, the predictive accuracy of CSS for 30-day and 1-year all-cause death and MACE were significantly higher (c-statistics, CSS versus SYNTAX score: P < 0.01 for 30-day and 1-year all-cause death; P < 0.05 for 30-day and 1-year MACE, respectively). Furthermore, in the multivariate Cox regression analysis, both EuroSCORE and CSS were identified as the independent predictors of 30-day and 1-year all-cause death and MACE, but the SYNTAX score was not. CONCLUSIONS: In the general practice among a high-risk population undergoing LM PCI, EuroSCORE and CSS might be independent predictors for 30-day and 1-year all-cause death and MACE. Furthermore, the CSS had a superior discriminatory ability in predicting the 30-day and 1-year clinical outcomes comparing with the SYNTAX score.

OBJECTIVES: Acute infection is a well-known provocative factor of acute myocardial infarction (AMI). Prognosis is worse when it is associated with sepsis. Coronary revascularization is reported to provide benefit in these patients; however, the optimal timing remains uncertain. METHODS: This retrospective study was performed at a tertiary center in Taipei from January 2010 to December 2017. 1931 patients received coronary revascularization indicated for AMI. Among these, 239 patients were hospitalized for acute infection but later developed AMI. Patients with either an ST-elevation myocardial infarct or the absence of obstructive coronary artery disease were excluded. Revascularization was performed via either percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG). We defined early and delayed revascularization groups if it was performed within or after 24 hours of the diagnosis of AMI, respectively. We evaluated whether the timing of revascularization altered 30-day and one-year all-cause mortality. RESULTS: At one month, 24 (26%) patients died in early revascularization group and 32 (22%) patients in delayed revascularization group. At one year, 40 (43%) and 59 (40%) patients died on early and delayed revascularization groups respectively. Early revascularization did not result in lower 30-day all-cause mortality (P = 0.424), and one-year all-cause mortality (Hazard ratio (HR): 0.935; 95% confidence interval (CI): 0.626-1.397, P = 0.742) than delay revascularization. CONCLUSIONS: Timing of coronary revascularization of post infectious acute coronary syndrome may be arranged according to individual risk category as those without sepsis.

Background: The severity of nonalcoholic fatty liver disease (NAFLD) has been found to be associated with atherosclerosis burden. However, whether liver fibrosis scores can be used to predict atherosclerosis progression, especially for patients with low calcium scores, remains undetermined. Methods: A total of 165 subjects who underwent repeated coronary computed tomography angiography (CCTA) and had low calcium scores (<100) were enrolled. The segment stenosis score (SSS) from the CCTA was measured, and the association between SSS progression and biochemical parameters was analyzed in addition to liver fibrosis scores, including nonalcoholic fatty liver disease fibrosis score (NFS), fibrosis-4 index (FIB-4), aspartate aminotransferase (AST) to platelet ratio index (APRI), and Forns score. Results: When compared with those without plaque at baseline (SSS = 0), subjects with plaque had higher blood pressure, higher coronary artery calcium (CAC) scores, and higher liver fibrosis scores, including Forns score, Fib-4, and NFS. During the medium follow-up interval of 24.7 months, 60 (39.4%) patients displayed SSS progression, while the remaining 105 (63.6%) patients showed no CAD progression. In a multivariate analysis, being male having a high diastolic blood pressure (DBP), and having a high NFS liver fibrosis score were independently associated with the odds ratio for SSS progression. Conclusions: Higher baseline blood pressure and liver fibrosis markers are associated with the presence of coronary artery disease (CAD) plaques in subjects in early CAD stages. For disease progression, the male gender, DBP, and NFS appear to be independently associated with coronary atherosclerosis plaque progression in subjects with low calcium scores.

AIMS: Physical activity has a protective effect against mortality and cardiovascular events in chronic kidney disease (CKD) patients. Nonetheless, how different levels of physical activity affect the health benefits in CKD remains unclear. This study aimed to investigate the dose-response effects of physical activity on mortality and major cardiorenal events in CKD. METHODS AND RESULTS: We evaluated a longitudinal cohort of 4508 Taiwanese CKD patients between 2004 and 2017. Physical activity was assessed by the NHANES questionnaire and quantified in metabolic equivalent-hours per week (MET-hour/week). Patients were categorized into highly active (≥7.5 MET-h/week), low-active (0.1 to <7.5 MET-h/week), or inactive (0 MET-h/week) groups. Cox regression and restricted cubic spline models were utilized to explore the association between physical activity and the risks of study outcomes, including all-cause mortality, end-stage renal disease (ESRD), and major adverse cardiovascular events (MACE, a composite of cardiovascular death, myocardial infarction, ischaemic stroke, and hospitalized heart failure). During a median follow-up of 686 days, 739 death, 1059 ESRD, and 521 MACE events occurred. Highly active group had the lowest chance of all study outcomes, followed by low-active and inactive groups (P < 0.001). Multivariable Cox regression showed that only highly active group was independently associated with lower risks for all-cause mortality [hazard ratio (HR) 0.62; 95% confidence interval (CI) 0.53-0.74], ESRD (HR 0.83, 95% CI 0.72-0.96), and MACE (HR 0.63, 95% CI 0.51-0.76) compared to the inactive group. The risks of MACE did not further decrease once physical activity surpassed 15 MET-h/week, indicating a U-shaped association. The results were consistent in the subgroup and sensitivity analyses. CONCLUSION: Physical activity of 7.5 to <15 MET-h/week is associated with lower risks of adverse cardiorenal outcomes and should be integrated into the care of CKD.
