The fibrosis-4 score is associated with long-term mortality in different phenotypes of acute heart failure.

BACKGROUND: Fibrosis-4 score (FIB4) was a non-invasive surrogate to estimate the amount of liver scarring in chronic hepatitis. Considering the presence of increased central venous pressure and congestive hepatopathy in patients with decompensated heart failure, we therefore investigated the prognostic values of FIB4 in acute heart failure (AHF) patients. METHOD: Patients hospitalised primarily for HF were drawn from an intramural registry. FIB4 was calculated according to age, aspartate aminotransferase, alanine aminotransferase and platelet count. All-cause mortality up to 5 years after discharge was obtained by linking to the national death registry. RESULTS: Among a total of 1854 participants, 940 patients died during a mean follow-up of 28.3 ± 21.8 months. FIB4 score was related to mortality and the composite of cardiovascular death or HF rehospitalisation, independent of age, sex, left ventricular ejection fraction, left atrial dimension, sodium and haemoglobin levels, estimated glomerular filtration rate, comorbidities, and medications [hazard ratio and 95% confidence interval of mortality: 1.009 (1.002-1.015), and the composite of cardiovascular death or HF hospitalisation: 1.020 (1.010-1.031)]. The prognostic value of FIB4 was predominantly in the subjects with heart failure and preserved or mildly reduced ejection fraction (HFpEF and HFmrEF), or coronary artery disease (CAD) than the counterparts [interaction p-value <0.001, and 0.004, respectively]. CONCLUSIONS: FIB4 was an independent predictor of survival in AHF patients, irrespective of the phenotypes of HF. The higher predictive value of mortality of FIB4 was observed in the subjects with HFpEF, HFmrEF or CAD.

The association of the steatosis severity in fatty liver disease with coronary plaque pattern in general population.

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.

Utilization of Amplitude-Integrated Electroencephalography to Predict Neurologic Function after Resuscitation in Adults with Cardiogenic Cardiac Arrest.

BACKGROUND: Amplitude-integrated electroencephalography (aEEG) has been used as a tool to recognize brain activity in children with hypoxic encephalopathy. OBJECTIVES: To assess the prognostic value of aEEG during the post-resuscitation period of adult cardiogenic cardiac arrest, comatose survivors were monitored within 24 h of a return of spontaneous circulation using aEEG. METHODS: Forty-two consecutive patients experiencing cardiac arrest were retrospectively enrolled, and a return of spontaneous circulation was achieved in all cases. These patients were admitted to the Coronary Intensive Care Unit due to cardiogenic cardiac arrest. The primary outcome was the best neurologic outcome within 6 months after resuscitation, and the registered patients were divided into two groups based on the Cerebral Performance Category (CPC) scale (CPC 1-2, good neurologic function group; CPC 3-5, poor neurologic function group). All patients received an aEEG examination within 24 h after a return of spontaneous circulation, and the parameters and patterns of aEEG recordings were compared. RESULTS: Nineteen patients were in the good neurologic function group, and 23 were in the poor group. The four voltage parameters (minimum, maximum, span, average) of the aEEG recordings in the good neurologic function groups were significantly higher than in the poor group. Moreover, the continuous pattern, but not the status epilepticus or burst suppression patterns, could predict mid-term good neurologic function. CONCLUSIONS: aEEG can be used to predict neurologic outcomes based on the recordings' parameters and patterns in unconscious adults who have experienced a cardiac collapse, resuscitation, and return of spontaneous circulation.

Systemic immune-inflammation index (SII) predicted clinical outcome in patients with coronary artery disease.

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.

Spirometric reference values in heathy Chinese adults in Taiwan: The secular changes and comparison with other Asian populations.

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.

2020 Consensus Statement of the Taiwan Hypertension Society and the Taiwan Society of Cardiology on Home Blood Pressure Monitoring for the Management of Arterial Hypertension.

To facilitate the applications of home blood pressure (HBP) monitoring in clinical settings, the Taiwan Hypertension Society and the Taiwan Society of Cardiology jointly put forward the Consensus Statement on HBP monitoring according to up-to-date scientific evidence by convening a series of expert meetings and compiling opinions from the members of these two societies. In this Consensus Statement as well as recent international guidelines for management of arterial hypertension, HBP monitoring has been implemented in diagnostic confirmation of hypertension, identification of hypertension phenotypes, guidance of anti-hypertensive treatment, and detection of hypotensive events. HBP should be obtained by repetitive measurements based on the " 722 " principle, which is referred to duplicate blood pressure readings taken per occasion, twice daily, over seven consecutive days. The " 722" principle of HBP monitoring should be applied in clinical settings, including confirmation of hypertension diagnosis, 2 weeks after adjustment of antihypertensive medications, and at least every 3 months in well-controlled hypertensive patients. A good reproducibility of HBP monitoring could be achieved by individuals carefully following the instructions before and during HBP measurement, by using validated BP devices with an upper arm cuff. Corresponding to office BP thresholds of 140/90 and 130/80 mmHg, the thresholds (or targets) of HBP are 135/85 and 130/80 mmHg, respectively. HBP-based hypertension management strategies including bedtime dosing (for uncontrolled morning hypertension), shifting to drugs with longer-acting antihypertensive effect (for uncontrolled evening hypertension), and adding another antihypertensive drug (for uncontrolled morning and evening hypertension) should be considered. Only with the support from medical caregivers, paramedical team, or tele- monitoring, HBP monitoring could reliably improve the control of hypertension.

Prognostic Comparison of the Estimations of Renal Function in Patients With Acute Heart Failure.

BACKGROUND: The prognostic significance of the eGFR calculated by either the four-level Race Chronic Kidney Disease-Epidemiology Collaboration study equation (CKD-EPI4R) or the Chinese-modified Modification of Diet in Renal Disease equation (cMDRD) has not been compared in Asian populations with acute heart failure (AHF).Methods and Results:A total of 3,044 patients hospitalized for AHF were enrolled. The National Death Registry was linked to identify deaths within a 5-year follow-up. Net reclassification improvement (NRI) was calculated to compare the prognostic value of either eGFR equation. During a median follow-up of 23.3 months, 1,424 (47%) patients died. Both eGFRcMDRDand eGFRCKD-EPI4Rwere independently predictive of death in the total study population (hazard ratio and 95% confidence intervals per 1-SD: 0.76, 0.71-0.81 and 0.74, 0.70-0.79, respectively), and in the subgroups of either reduced (HFrEF) or preserved (HFpEF) ejection fraction, after accounting for important confounders. With reference to eGFRcMDRD, eGFRCKD-EPI4Rmay improve the NRI by 2.0% (0.8-3.2%) for the prediction of death. The prognostic value of the CKD stages categorized by eGFRCKD-EPI4Rsignificantly outperformed eGFRcMDRDwith a categorical NRI of 9.5% (4.7-14.3%) in the total study population, 11.5% in HFrEF, and 8.3% in HFpEF. CONCLUSIONS: Both eGFRcMDRDand eGFRCKD-EPI4Rwere independently associated with long-term survival in patients with AHF. However, the CKD stages derived from eGFRCKD-EPI4Rimproved the risk stratification of death, compared with eGFRcMDRD.

2019 Consensus of the Taiwan Hypertension Society and Taiwan Society of Cardiology on the Clinical Application of Central Blood Pressure in the Management of Hypertension.

The Taiwan Society of Cardiology (TSOC) and the Taiwan Hypertension Society (THS) have appointed a joint consensus group for the 2019 Consensus of the TSOC and THS on the Clinical Application of Central blood pressure (BP) in the Management of Hypertension with the aim of formulating a management consensus on the clinical application of central BP in the management of hypertension. This consensus document focuses on the clinical application of central BP in the care of patients with hypertension. The major determinants of central BP are increased arterial stiffness and wave reflection, which are also the dominant hemodynamic manifestations of vascular aging. Central BP can be measured noninvasively using various techniques, including with convenient cuff-based oscillometric central BP monitors. Noninvasive central BP is better than conventional brachial BP to assess target organ damage and long-term cardiovascular outcomes. Based on the analysis of long-term events, a central BP threshold of 130/90 mmHg for defining hypertension has been proposed. Recent studies have suggested that a central BP strategy to confirm a diagnosis of hypertension may be more cost-effective than conventional strategies, and that guiding hypertension management with central BP may result in the use of fewer medications to achieve BP control. Although noninvasive measurements of brachial BP are inaccurate and central BP has been shown to carry superior prognostic value beyond brachial BP, the use of central BP should be justified in studies comparing central BP-guided therapeutic strategies with conventional care for cardiovascular events.

InVestiGation of the Association of Physical Activity and Sedentary Behavior with tHe Occurrence of Future Cardiovascular Disease and Long Term Outcome in General Population Using the HEALTHCARE Database (VGH-HEALTHCARE).

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.

Association between nonsteroidal anti-inflammatory drugs and atrial fibrillation among a middle-aged population: a nationwide population-based cohort.

AIMS: It remains inconclusive whether the use of nonsteroidal anti-inflammatory drugs (NSAIDs) increases the risk of atrial fibrillation (AF), especially in middle-aged Asian populations. In this study, we evaluated the association between NSAID use and the risk of AF in a nationwide population-based study of middle-aged individuals in Taiwan. METHODS: A nested case-control study was conducted using the National Health Insurance Research Database (NHIRD) in Taiwan. We identified the cases with a diagnosis of AF (ICD-9-CM codes: 427.31) and the matched controls from three independent Longitudinal Health Insurance Databases (LHIDs) derived from the NHIRD from data collected from 2001 to 2013. Conditional logistic regression models with covariate adjustment were performed to evaluate the association between NSAID use and the risk of AF. RESULTS: A total of 57 058 participants (28 529 AF cases and 28 529 matched controls) were included. Participants with NSAID use had an elevated risk of AF compared to non-users [adjusted odds ratio (AOR) = 1.18, 95% confidence interval (CI): 1.14-1.23]. When further assessing the effects of different classes of NSAIDs on the risk of AF, the results showed that participants who used non-selective NSAIDs had a significantly elevated risk of AF (AOR = 1.18, 95% CI: 1.13-1.23), as did participants with a combined use of selective and non-selective NSAIDs (AOR = 1.30, 95% CI: 1.21-1.39). CONCLUSIONS: NSAID use was associated with an increased risk of AF occurrence among the participants included in our study cohort. Closely monitoring the adverse effects of NSAID treatment on the risk of AF will be important, particularly among individuals at high risk.

Coronary Artery Bypass Surgery versus Percutaneous Coronary Intervention for Left Main Coronary Artery Disease with Chronic Kidney Disease.

Percutaneous coronary intervention (PCI) has emerged as an alternative treatment to coronary artery bypass grafting (CABG) in patients with unprotected left main coronary artery disease (ULMCAD). However, the optimal treatment for ULMCAD concomitant with chronic kidney disease (CKD) was rarely addressed. Herein, we compare the long-term outcomes of these patients treated with CABG or PCI.From January 2004 to December 2010, 185 patients with ULMCAD and CKD undergoing PCI (n = 84) or CABG (n = 101) were matched for the selection criteria. The primary end points included all-cause death, myocardial infarction (MI), stroke, repeat revascularization and major adverse cardiovascular and cerebrovascular event (MACCE).The mean age was 73.4 ± 10.3 years with male (84%) predominance. Baseline characteristics of both groups were similar, except that patients in CABG group were more frequently associated with significant stenosis of right coronary artery and triple vessel disease. Furthermore, most patients belonged to higher surgical risk population (EuroSCORE ≥ 6, PCI group: 80.9%, CABG group: 75.2%). After treatment, the 30-day mortality was 3.5% in PCI and 8.9% in CABG (P = 0.14). During the median follow-up of 3.5 years, the risk of MACCE (67% versus 55%, P = 0.048), MI (15.5% versus 6.9%, P = 0.024), and repeat revascularization (30.9% versus 7.9%, P < 0.001) was significantly higher in the PCI compared with CABG. There were no significant differences in long-term all-cause death, stroke, and impact on renal function.CABG was associated with significantly less long-term risk of MI and repeat revascularization in patients with ULMCAD and CKD.

Determinants and Prognostic Impact of Hyperuricemia in Hospitalization for Acute Heart Failure.

BACKGROUND: Hyperuricemia is a prognostic factor in patients with chronic heart failure, but whether uric acid level can predict clinical outcome of acute heart failure (AHF) remains to be elucidated. We therefore investigated the association of uric acid with mortality in patients hospitalized for AHF. METHODS AND RESULTS: Data for patients hospitalized for AHF were drawn from an intramural registry. Biochemistry data, echocardiographic characteristics, and uric acid level were collected. National Death Registry was linked for the identification of mortality data. Among a total of 1,835 participants (age, 75 ± 13 years, 68% men), 794 patients died during follow-up. Patients who died were older, had lower hemoglobin and estimated glomerular filtration rate, and higher pulmonary artery systolic pressure, NT-proBNP, and uric acid. Uric acid was a significant predictor of mortality on univariate analysis (HR per 1 SD, 1.18; 95% CI: 1.11-1.26) and in multivariate Cox models (HR, 1.15; 95% CI: 1.02-1.29). Survival analysis showed an increasing risk of death along the quartile distribution of uric acid level. Given renal function, cardiac performance, and kidney perfusion as major determinants of hyperuricemia, the prognostic impact of uric acid level was diminished as renal function deteriorated. CONCLUSIONS: Uric acid level was an independent predictor of mortality in patients hospitalized for AHF, but the prognostic impact of hyperuricemia was attenuated by worsening renal function.

Comparison of Bare-Metal Stent and Drug-Eluting Stent for the Treatment of Patients Undergoing Percutaneous Coronary Intervention for Unprotected Left Main Coronary Artery Disease - Long-Term Result from a Single Center Experience.

BACKGROUND: Percutaneous coronary intervention (PCI) has become an alternative treatment for left main (LM) coronary artery disease. The aim of our study was to compare long-term clinical outcomes of patients undergoing unprotected LM PCI with bare-metal stent (BMS) or drug-eluting stent (DES) in a high-risk population. METHODS AND RESULTS: We enrolled 223 consecutive patients with unprotected LM coronary artery disease undergoing PCI (mean age: 71.1 ± 11.2 years, 187 male), including 94 patients receiving BMS and 129 patients receiving DES. The patients receiving DES had a significantly higher SYNTAX score (p = 0.05). During the mean follow-up period of 2.5 years, there were 31 cardiovascular deaths (BMS: 21 cases, DES: 10 cases, p = 0.04 by log-rank test), 56 major adverse cardiovascular events (MACE, including cardiovascular death, non-fatal myocardial infarction (MI) and clinical-driven target lesion revascularization; BMS: 33 cases, DES: 23 cases, p = 0.03 by log-rank test) and 6 cases with definite/probable stent thrombosis (BMS: 5 cases, DES: 1 cases, p = 0.09). In multivariate Cox analysis, the use of DES was identified as an independent protective factor against cardiovascular death [hazard ratio (HR) = 0.34, 95% confidence interval (Cl) = 0.15-0.79, p = 0.01] and MACE (HR = 0.50, 95% CI = 0.28-0.88, p = 0.02). The clinical outcome analyses in propensity-score matched the cohort (87 matched pair of patients receiving BMS and DES) and yielded similar results. CONCLUSIONS: In the general practice among a high-risk population undergoing unprotected LM PCI, the use of DES appeared to be beneficial in reducing the risk of long-term cardiovascular death and MACE. KEY WORDS: Bare-mental stent; Drug-eluting stent; Left main coronary artery disease; Percutaneous coronary intervention.

Asymmetric dimethylarginine and long-term adverse cardiovascular events in patients with type 2 diabetes: relation with the glycemic control.

BACKGROUND AND AIMS: Elevated plasma asymmetric dimethylarginine (ADMA) levels have been observed in patients with insulin resistance and diabetes, and have been reported to predict adverse cardiovascular events in type 2 diabetic patients. However, the relationship between ADMA and glycemic control in patients with type 2 diabetes remained controversial. METHODS AND RESULTS: We evaluated 270 patients with type 2 diabetes and measured their plasma ADMA and hemoglobin A1c (HbA1c) levels by high performance liquid chromatography. The mean age was 67 ± 12 years. The mean plasma ADMA and HbA1c level were 0.46 ± 0.09 µmol/l and 7.8 ± 1.6%, respectively. There was no significant correlation between plasma ADMA level and HbA1c level (r = -0.09, p = 0.13). During the median follow-up period of 5.7 years (inter-quartile range: 5.0 - 7.3 years), major adverse cardiovascular event (MACE, including cardiovascular death, myocardial infarction and stroke) was observed in 55 patients (20.4%). Multivariate Cox regression analysis revealed that the ADMA tertile was an independent risk factor for MACE (ADMA tertile III versus ADMA tertile I: p = 0.026, HR: 2.31, 95% CI: 1.10 - 4.81). The prognosis predictive power of ADMA disappeared in patients with well glycemic control (HbA1c ≤6.5%), and the ADMA-HbA1c interaction p value was 0.01. CONCLUSIONS: In patients with type 2 diabetes, ADMA might be an independent risk factor for long-term adverse cardiovascular events. However, ADMA was not correlated with serum HbA1c level, and in diabetic patients with HbA1c ≤6.5%, elevated ADMA level was no longer associated with increased risk of long-term prognosis. Our findings suggested that the prognosis predictive value of ADMA in type 2 diabetes might be modified by the glycemic control.

The impacts of anemia burden on clinical outcomes in patients with out-of-hospital cardiac arrest.

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) has low survival rates, and few patients achieve a desirable neurological outcome. Anemia is common among OHCA patients and has been linked to worse outcomes, but its impact following the return of spontaneous circulation (ROSC) is unclear. This study examines the relationship between anemia burden and clinical outcomes in OHCA patients. HYPOTHESIS: Higher anemia burden after ROSC may be related to higher mortality and worse neurologic outcomes. METHODS: Patients who experienced OHCA and had ROSC were enrolled retrospectively. Anemia burden was defined as the area under curve from the target hemoglobin level over a 72-h period after OHCA. Hemoglobin level was measured at 12-h intervals. The clinical outcomes of the study included mortality and neurological outcomes at Day 30. RESULTS: The study enrolled 258 nontraumatic OHCA patients who achieved ROSC between January 2017 and December 2021. Among the 162 patients who survived more than 72 h, a higher anemia burden, specifically target hemoglobin levels below 7 (hazard ratio [HR]: 1.129, 95% confidence interval [CI]: 1.013-1.259, p = .029), 8 (HR: 1.099, 95% CI: 1.014-1.191, p = .021), and 9 g/dL (HR: 1.066, 95% CI: 1.001-1.134, p = .046) was associated with higher 30-day mortality. Additionally, anemia burden with target hemoglobin levels below 7 (HR: 1.129, 95% CI: 1.016-1.248; p = .024) and 8 g/dL (HR: 1.088; 95% CI: 1.008-1.174, p = .031) was linked to worse neurological outcomes. CONCLUSIONS: Anemia burden predicts 30-day mortality and neurological outcomes in OHCA patients who survive more than 72 h. Maintaining higher hemoglobin levels within the first 72 h after ROSC may improve short-term outcomes.

Successful catheter ablation reduces the risk of cardiovascular events in atrial fibrillation patients with CHA2DS2-VASc risk score of 1 and higher.

AIMS: It is not known if successful catheter ablation for atrial fibrillation (AF) improves the patient's long-term cardiovascular outcomes. This study investigated the long-term outcomes and mortality of AF patients at high risk who received antiarrhythmic medication and catheter ablation. METHODS AND RESULTS: The propensity scores for AF were calculated for each patient and were used to assemble a cohort of 174 AF patients with ablation who were compared with an equal number of AF patients without ablation. Composite cardiovascular end points (major adverse cardiovascular event, MACE), including mortality and vascular events in the medically treated patients representing the control group (group 1), were compared with those in the ablation-treated patients (group 2). The rates of the total mortality (2.95% vs. 0.74% per year; P < 0.01), cardiovascular death (1.77% vs. 0% per year; P = 0.001), and ischaemic stroke/transient ischaemic attack (2.21% vs. 0.59% per year; P = 0.02) were higher in group 1 than group 2, respectively. A multivariate Cox regression analysis of the MACE scores showed that a higher CHA2DS2-VASc score [hazard ratio (HR) = 1.309 per increment of score, 95% confidence interval (CI) = 1.06-1.617; P = 0.01] and the performance of the ablation procedure (HR = 0.225, CI = 0.076-0.671; P = 0.007) were independent predictors of a MACE. In patients who received catheter ablation, recurrence of any atrial arrhythmia was a predictor of vascular events and total mortality (P < 0.05). CONCLUSION: In AF patients with CHA2DS2-VASc score ≥1, catheter ablation of AF reduced the risk of the total/cardiovascular mortality and total vascular events. Atrial fibrillation recurrence predicts long-term cardiovascular outcomes, as well as the CHA2DS2-VASc score.

The Impacts of Serum Uric Acid on arterial hemodynamics and Cardiovascular Risks.

UNLABELLED: Hyperuricemia, and its clinical manifestation gout, is a metabolic disease process that has been recognized since the dawn of medical inquiry. Uric acid was hypothesized to be a mediator of cardiovascular disease for period of time. Epidemiological correlations of hyperuricemia with hypertension and cardiovascular events were evident for two centuries' studies. With recent animal studies shedding light on the causal mechanisms of hypertension, and clinical trials suggesting that urate-lowering therapy can lower blood pressure, there appears to be growing evidence of a connection between hyperuricemia and cardiovascular disease. To help bring this recent uric acid research into context, we have undertaken this narrative review of hyperuricemia, hypertension, its hemodynamics and its outcomes, and the risk for cardiovascular diseases. KEY WORDS: Cardiovascular risk; Hemodynamics; Uric acid.

Sex and age differences of major cardiovascular events in patients after percutaneous coronary intervention.

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.

Association between Coronary Artery Plaque Progression and Liver Fibrosis Biomarkers in Population with Low Calcium Scores.

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.
