RESUMO
BACKGROUND: Compared with conventional bilateral femoral (BF) approach, radial plus ipsilateral femoral (RF) approach may be feasible in the percutaneous intervention for iliac artery chronic total occlusion (CTO). METHODS: We included patients who underwent iliac CTO intervention between August 2009 and July 2018 in a tertiary referral center in Korea. RESULTS: A total of 83 patients were enrolled in this study. Of them, 51 and 32 patients were categorized into RF and BF initial access groups, respectively. The overall success rates were 98.0% and 96.7% in RF and BF group, respectively, and the techniques were also similar including use of bilateral wiring, stent type and profile, and post balloon but longer procedure time in the BF group. Additional contralateral femoral access was needed in 6 patients for the treatment of contralateral lesions, distal embolization, and due to tortuous right subclavian artery. Periprocedural complications including vascular injury, iliac perforation, and distal embolization occurred similarly in both groups with numerically lower rate of periprocedural bleeding in the RF group (9.8%) than in the BF group (21.9%). Clinical follow-up at 6 months showed there were no difference in the rates of death, cardiovascular death, target-limb reintervention, and unplanned target limb amputation in both groups. CONCLUSIONS: RF approach for iliac CTO intervention was related to similar technical success rate with acceptable periprocedural safety outcomes compared with conventional BF approach.

OBJECTIVES: Previous epidemiological studies have limitations in revealing whether cardiovascular disease (CVD) incidence is mediated by interim occurrence of other metabolic diseases in otherwise healthy nonalcoholic fatty liver disease (NAFLD) patients. METHODS: The study population consisted of 334 280 healthy subjects who had had the National Health check-ups in South Korea from 2009 to 2014. The fatty liver index (FLI) was used to identify subjects with NAFLD. CVD was defined as occurrence of a composite of cardiovascular death, myocardial infarction, ischemic stroke, or coronary revascularization. The association between FLI and CVD incidence was analyzed using time-dependent Cox regression analyses. RESULTS: The study population was categorized into quartile groups according to FLI (range: Q1, 0-4.9; Q2, 5.0-12.5; Q3, 12.6-31.0; Q4, >31.0). The median follow-up duration was 5.4 years, during which subjects with higher FLIs experienced CVD more frequently than did those with lower FLIs [Q1, 215 (0.3%); Q2, 498 (0.6%); Q3, 753 (0.9%); Q4, 981 (1.2%); P < 0.001]. Adjustment of baseline characteristics revealed that a higher FLI was independently associated with an increased risk for CVD [hazard ratio between Q4 and Q1, 1.86; 95% confidence interval (CI), 1.59-2.17; P < 0.001]. The association between them remained statistically significant (hazard ratio between Q4 and Q1, 1.92; 95% CI, 1.63-2.25; P < 0.001) after further adjustment for the interim events (diabetes, hypertension, heart failure, and atrial fibrillation). CONCLUSIONS: Otherwise healthy NAFLD patients progressed to develop CVD independently of the interim occurrence of other metabolic diseases, which emphasizes the importance of NAFLD as a potential therapeutic target for prevention of CVD.

BACKGROUND AND OBJECTIVES: Aortic valve replacement (AVR) is the treatment of choice in severe symptomatic aortic stenosis (AS) patients. However, a substantial number of elderly patients refuse AVR and treated medically. We investigated their long-term prognosis. METHODS: From January 2005 to December 2016, we analyzed elderly patients with severe symptomatic AS who refused to have AVR. RESULTS: After screening of total 534 patients, we analyzed total 180 severe symptomatic AS patients (78±7 years old, 96 males). Hypertension was the most common cardiovascular risk factor (72%) and the most common symptom was dyspnea (66%). Calculated aortic stenosis area was 0.73±0.20 cm² and mean left ventricular ejection fraction (LVEF) was 57.8±12.2%. Total 102 patients died during follow-up period (39.1±31.0 months). One-, 3-, and 5-year all-cause mortality rate was 21.1±3.0%, 43.1±3.8%, and 56.5±4.2%, respectively. Of them, 87 died from cardiac causes, and 1-, 3-, and 5-year cardiac mortality rate was 18.0±2.9%, 38.2±3.8%, and 50.7±4.3%, respectively. Their all-cause mortality and cardiac mortality were significantly higher than those of controls. Univariate analysis showed that age, anemia, LVEF, and Log N-terminal pro B-type natriuretic peptide (NT-proBNP) were significant parameters in all-cause mortality (p<0.001, p=0.001, p=0.039, and p=0.047, respectively) and in cardiac mortality (p<0.001, p<0.001, p=0.046, and p=0.026, respectively). Multivariate analysis showed that age and anemia were significant prognostic factors for cardiac and all-cause mortality. CONCLUSIONS: In elderly severe symptomatic AS patients who treated medically, their 1-, 3- and 5-year all-cause mortality rate was 21.1±3.0%, 43.1±3.8%, and 56.5±4.2%, respectively. Age and anemia were significant prognostic factors for cardiac and all-cause mortality.
