Brachial-ankle PWV for predicting clinical outcomes in patients with acute stroke.

BACKGROUND: Although brachial-ankle pulse wave velocity (baPWV) is well-known for predicting the cardiovascular mortality and morbidity, its anticipated value is not demonstrated well concerning acute stroke. METHODS: Total 1557 patients with acute stroke who performed baPWV were enrolled. We evaluated the prognostic value of baPWV predicting all-cause death and vascular death in patients with acute stroke Results: Highest quartile of baPWV was ≥23.64 m/s. All-caused deaths (including vascular death; 71) were 109 patients during follow-up periods (median 905 days). Multivariate Cox regression analysis revealed that patients with the highest quartile of baPWV had higher risk for vascular death when they are compared with patients with all other three quartiles of baPWV (Hazard ratio with 95% confidence interval [CI] 1.879 [1.022-3.456], p = .042 for vascular death). CONCLUSION: High baPWV was a strong prognostic value of vascular death in patients with acute stroke.

The Curves Exercise Suppresses Endotoxemia in Korean Women with Obesity.

Obesity and metabolic syndrome is a worldwide pandemic and associated with high cardiovascular risk. Metabolic endotoxemia (ME) is thought to be an underlying molecular mechanism. It triggers toll-like receptor 4-mediated inflammatory adipokines and causes a chronic low grade inflammatory status, which results in cardiovascular risk increase. Exercise is the best nonpharmacological treatment to improve prognosis. In this study, we examined the circulating endotoxin level in Korean obese women and investigated effects of exercise on it. Women over body mass index (BMI) 25 kg/m² participated in a resistance training exercise, Curves. At baseline and after 12 weeks exercise, tests including blood samples were taken. In Korean obese women, the fasting endotoxin was 1.45 ± 0.11 EU/mL. Ingestion of a high calorie meal led to a peak level after 2 hours (postprandial 2 hours [PP2]) and a significant rise over the 4 hours (postprandial 4 hours [PP4]) in it (1.78 ± 0.15 and 1.75 ± 0.14 EU/mL for PP2 and PP4, P < 0.05 vs. fasting). After exercise, BMI and hip circumference were reduced significantly. The total cholesterol (TC) at fasting, PP2 and PP4 were decreased significantly. All levels of circulating endotoxin at fasting, PP2 and PP4 showed reduction. But, the peak change was only significant (baseline vs. 12 weeks for PP2; 1.78 ± 0.15 vs. 1.48 ± 0.06 EU/mL, P < 0.05). We report the circulating endotoxin level in Korean obese women for the first time. Also, we establish that energy intake leads to endotoxemia and exercise suppresses the peak endotoxemia after meal. It suggests an impact for a better prognosis in obese women who follow regular exercise.

Elevation of Serum APE1/Ref-1 in Experimental Murine Myocarditis.

Myocarditis is an inflammatory disease of the myocardium that causes cardiogenic shock and death. However, endomyocardial biopsy that is, the gold standard for a diagnosis is limited. Apurinic/apyrimidinic endonuclease 1/redox effector factor-1 (APE1/Ref-1) is a multifunctional protein, which is involved in DNA-based excision repair pathway, and in redox signaling, its changes are observed in various cardiovascular diseases including hypertension and coronary artery disease. We analyzed serum APE1/Ref-1 in experimental murine myocarditis. To induce myocarditis, coxsackievirus B3 was injected intraperitoneally to BALB/c mice. The serum APE1/Ref-1, N-terminal pro-B-type natriuretic peptide (NT-proBNP) and troponin I were measured. The histology and virus titers measurements were performed. The troponin I and inflammation were significantly elevated at day 3, peaked to day 7 and decreased at day 10. The NT-proBNP and virus titers were significantly peaked at day 3, and dropped at day 7 and 10. The serum APE1/Ref-1 was gradually raised and its elevation is still maintained until a later time, namely day 10. Also, its level was positively correlated with myocardial inflammation, reflecting severity of myocardial injury. We suggest that serum APE1/Ref-1 can be used to assess for myocardial injury in viral myocarditis without endomyocardial biopsy.

The Association of CHADS-P2A2RC Risk Score With Clinical Outcomes in Patients Taking P2Y12 Inhibitor Monotherapy After 3 Months of Dual Antiplatelet Therapy Following Percutaneous Coronary Intervention.

BACKGROUND AND OBJECTIVES: Concerns remain that early aspirin cessation may be associated with potential harm in subsets at high risk of ischemic events. This study aimed to assess the effects of P2Y12 inhibitor monotherapy after 3-month dual antiplatelet therapy (DAPT) vs. prolonged DAPT (12-month or longer) based on the ischemic risk stratification, the CHADS-P2A2RC, after percutaneous coronary intervention (PCI). METHODS: This was a sub-study of the SMART-CHOICE trial. The effect of the randomized antiplatelet strategies was assessed across 3 CHADS-P2A2RC risk score categories. The primary outcome was a major adverse cardiac and cerebral event (MACCE), a composite of all-cause death, myocardial infarction, or stroke. RESULTS: Up to 3 years, the high CHADS-P2A2RC risk score group had the highest incidence of MACCE (105 [12.1%], adjusted hazard ratio [HR], 2.927; 95% confidence interval [CI], 1.358-6.309; p=0.006) followed by moderate-risk (40 [1.4%], adjusted HR, 1.786; 95% CI, 0.868-3.674; p=0.115) and low-risk (9 [0.5%], reference). In secondary analyses, P2Y12 inhibitor monotherapy reduced the Bleeding Academic Research Consortium (BARC) types 2, 3, or 5 bleeding without increasing the risk of MACCE as compared with prolonged DAPT across the 3 CHADS-P2A2RC risk strata without significant interaction term (interaction p for MACCE=0.705 and interaction p for BARC types 2, 3, or 5 bleeding=0.055). CONCLUSIONS: The CHADS-P2A2RC risk score is valuable in discriminating high-ischemic-risk patients. Even in such patients with a high risk of ischemic events, P2Y12 inhibitor monotherapy was associated with a lower incidence of bleeding without increased risk of ischemic events compared with prolonged DAPT.

Immunoglobulin G4-Related Myocarditis with Eosinophilic Infiltration: A Case Report.

Immunoglobulin G4 (IgG4)-related disease (IgG4-RD) is a fibroinflammatory disorder that can involve any organ system; however, myocarditis is extremely rare. A 52-year-old male with dyspnea and chest discomfort underwent cardiac MRI that revealed edema and nodular, patchy, mesocardial and subendoardial delayed enhancement of left ventricle, suggesting myocarditis. Laboratory findings revealed elevated serum IgG4 and eosinophilia. Cardiac biopsy confirmed eosinophilic myocarditis with IgG4-positive cells. Here, we present an unusual case of IgG4-RD manifesting as eosinophilic myocarditis.

Prevalence and Prognostic Implications of Worsening Renal Function After Acute Myocardial Infarction.

We sought to investigate the relation between worsening renal function (WRF) at 1-year follow-up and clinical outcomes at 3 years after acute myocardial infarction (AMI). We analyzed data from 13,104 patients enrolled in the national AMI registry from November 2011 to December 2015. Patients with all-cause death, recurrent myocardial infarction (re-MI), and rehospitalization for heart failure at 1-year follow-up after AMI were excluded. A total of 6,235 patients were extracted and divided into WRF and non-WRF groups. WRF was defined as a ≥25% decrease in estimated glomerular filtration rate (eGFR) from baseline to 1-year follow-up. The primary outcome was 3-year major adverse cardiac events, a composite of all-cause death, re-MI, and rehospitalization for heart failure. On average, a -1.5 ml/min/1.73 m2/y rate of decrease in eGFR was exhibited, and 575 patients (9.2%) exhibited WRF at 1-year follow-up. After multiple adjustments, WRF at 1-year follow-up was independently associated with increased risks of major adverse cardiac events (adjusted hazard ratio 1.498, 95% confidence interval 1.113 to 2.016, p = 0.01), all-cause death, and re-MI at 3-year follow-up. Older age, female, diabetes mellitus, hypertension, non-ST-segment elevation AMI, anterior AMI, anemia, left ventricular ejection fraction <35%, and baseline eGFR <30 ml/min/1.73 m2 were identified as independent predictors of WRF after AMI. In conclusion, WRF at 1-year follow-up after AMI intuitively seems like a risk marker indicating multiple co-morbidities. Monitoring serum creatinine in patients at 1-year follow-up after AMI may help to identify those who are at the highest risk and guide effective long-term therapeutics.

Age-related difference in the impact of diabetes mellitus on all-cause mortality after acute myocardial infarction.

AIM: To test the hypothesis that the impact of diabetes mellitus on clinical outcomes after acute myocardial infarction (AMI) can vary by age. METHODS: A total of 12,600 AMI patients from the Korea Acute Myocardial Infarction Registry-National Institute of Health (KAMIR-NIH) between November 2011 and December 2015 was classified into young (n = 3,590 [29%]) and old (n = 9,010 [72%]). Those less than 55 years of age were considered young. We performed comparisons of baseline characteristics, in-hospital treatments, and 3-year clinical outcomes between patients with and without diabetes after stratification according to age group. RESULTS: The prevalence of diabetes mellitus was 27% in the young AMI group. In the multivariable adjusted model of the entire cohort, diabetes mellitus was associated strongly with 3-year all-cause mortality (13% vs. 6.8%; adjusted hazard ratio [HR], 1.318; 95% confidence interval [CI], 1.138-1.526; P<0.001). When the entire cohort was subdivided into two age groups, young diabetic patients showed a 107% higher mortality rate than those without diabetes (adjusted HR, 2.07 [1.15-3.72];P = 0.015). Meanwhile, old diabetic patients had a 25% higher risk of mortality than non-diabetic patients (adjusted HR, 1.25 [1.08-1.46];P = 0.004). The interaction of diabetes with age was significant (adjusted P for interaction = 0.008). CONCLUSIONS: Diabetes mellitus is not uncommon in younger AMI patients, and the relative risk of 3-year mortality is significantly higher in young patients than in older counterparts. More aggressive treatments are needed to prevent future cardiovascular events in younger patients after AMI.

Ambulatory blood pressure response to S-amlodipine in Korean adult patients with uncontrolled essential hypertension: A prospective, observational study.

Although amlodipine is recommended as the first-line therapy for the treatment of hypertension, its use is limited by its potential side effects. S-amlodipine is expected to be able to minimize side effects of amlodipine with a similar antihypertensive effect by removing the malicious R-chiral form. However, sustainable blood pressure control with S-amlodipine has not been well established yet. The purpose of the current study was to evaluate ambulatory blood pressure (ABP) profiles before and after a 12-week treatment of S-amlodipine. Patients received once-daily S-amlodipine 2.5 or 5 mg. ABP during 24 hr and office blood pressure were measured at baseline and after the 12-week treatment. Primary endpoints were changes of systolic and diastolic 24 hr ABP. After 12-week S-amlodipine treatment, mean systolic ABP (-15.1 ± 16.2 mmHg, p < .001) and diastolic ABP (-8.9 ± 9.8 mmHg, p < .001) were decreased significantly. Both daytime and night-time mean systolic BP and diastolic BP were also significantly decreased after the 12-week treatment. Global trough-to-peak ratio and smoothness index after 12-week S-amlodipine treatment were .75 and .79 for SBP and .65 and .61 for DBP, respectively. Age ≥65 years (hazard ratio [HR]: 3.13; 95% confidence interval [CI]: 1.67-14.3) and nonalcohol drinking (HR: 3.09; 95% CI: 1.34-7.17) were independent clinical factors for target ABP achievement. Adverse drug reactions (ADR) were developed in 16 (6.4%) patients, including two (.8%) cases of peripheral edema. In conclusion, this study demonstrated the efficacy and safety of S-amlodipine in patients with uncontrolled essential hypertension.

Recurrent pericarditis after chemotherapy for acute myeloid leukemia: a case report and a modern approach to chemotherapy-induced pericarditis.

Chemotherapy-induced pericarditis has been reported in a limited number of case series. Furthermore, the management of acute pericarditis associated with chemotherapy is not standardized. In a few case reports, pericarditis associated with chemotherapy has been treated with pericardiocentesis or anti-inflammatory drugs such as steroid or nonsteroidal anti-inflammatory drugs. Recently, colchicine was introduced as an effective tool in order to manage idiopathic recurrent pericarditis. However, the effectiveness of colchicine in chemotherapy-induced pericarditis has never been reported. We report a case of recurrent pericarditis associated with chemotherapy, which was successfully treated with colchicine and ibuprofen. We maintained colchicine when the patient required repeated chemotherapy for relapsed leukemia. And the concomitant use of colchicine prevented the patient from the full development of acute pericarditis. Colchicine may be effective in the treatment and prevention not only of idiopathic recurrent pericarditis but also of acute pericarditis associated with chemotherapy as in this case.

Difficulties in Differentiating Cardiac Lymphoma and Metastasis Based on Radiologic Features: Two Case Reports.

Cardiac tumors are rare diseases with various imaging findings. However, differentiating cardiac tumors based on imaging findings is challenging because of similarities in imaging features. We present two cases of cardiac tumors, including primary cardiac lymphoma and cardiac metastasis, in which the differential diagnosis was difficult.

Adherence to triple-component antihypertensive regimens is higher with single-pill than equivalent two-pill regimens: A randomized controlled trial.

Using a single-pill combination (SPC) for hypertension (HTN) treatment resulted in better adherence and persistence than a free-equivalent combination in previous observational studies. The aim of this study is to confirm superior adherence with a triple-component SPC compared with an equivalent two-pill regimen in a randomized controlled trial (RCT) using a medication event monitoring system (MEMS). This is a multicenter, open-label, RCT. Subjects were persons with HTN whose clinic blood pressure was not adequately controlled (systolic >140 mmHg or diastolic >90 mmHg) with a dual combination. Eligible patients were randomized to either the triple-component SPC (olmesartan/amlodipine/hydrochlorothiazide 20/5/12.5 mg) group or the equivalent two-pill (olmesartan/hydrochlorothiazide 20/12.5 mg + amlodipine 5 mg) group and maintained for 12 weeks. Primary outcomes were the difference in percentage of doses taken (PDT) and percentage of days with the prescribed dose taken correctly (PDTc) between the single- and two-pill therapy groups, calculated from MEMS data. From 8 hospitals, 145 patients with HTN were randomized. The single-pill group had significantly higher PDT and PDTc than the two-pill group: median (25-75 percentile) PDT 95.1 (86.7-100.0) versus 92.1 (73.0-97.3); and PDTc 91.0 (79.4-96.5) versus 88.6 (69.2-96.3%), P = 0.04 for both by the Wilcoxon rank sum test. The single-pill combination of the triple-component antihypertensive regimen showed better adherence than the equivalent two-pill therapy. Reducing pill burden by means of a single-pill combination is an effective strategy for enhancing adherence to multiple-agent antihypertensive therapy. Study Highlights WHAT IS THE CURRENT KNOWLEDGE ON THE TOPIC? Previous studies suggested that the use of a single-pill combination (SPC) in hypertension (HTN) treatment produced better adherence and persistence than a free-equivalent combination. However, supportive data are confined to dual-component SPC and came from observational studies using medication possession ratio as an outcome. WHAT QUESTION DID THIS STUDY ADDRESS? The objective of this study is to investigate whether a triple-component SPC improved medication adherence over an equivalent two-pill combination therapy in a randomized controlled trial using medication event monitoring systems. WHAT DOES THIS STUDY ADD TO OUR KNOWLEDGE? Medication adherence in the SPC group was superior to that of two-pill group, confirming previous findings from observational studies. HOW MIGHT THIS CHANGE CLINICAL PHARMACOLOGY OR TRANSLATIONAL SCIENCE? This finding strongly supports the current HTN treatment guideline to prefer SPC with a higher level of evidence.

Comparison of in-hospital outcomes of patients with vs. without ischaemic cardiomyopathy undergoing veno-arterial-extracorporeal membrane oxygenation.

AIMS: This study aimed to investigate differences in baseline and treatment characteristics, and in-hospital mortality according to the aetiologies of cardiogenic shock in patients undergoing veno-arterial-extracorporeal membrane oxygenation (VA-ECMO). METHODS AND RESULTS: The RESCUE registry is a multicentre, observational cohort that includes 1247 patients with cardiogenic shock from 12 centres. A total of 496 patients requiring VA-ECMO were finally selected, and the study population was stratified by cardiogenic shock aetiology [ischaemic cardiomyopathy (ICM, n = 342) and non-ICM (NICM, n = 154)]. The primary outcome of interest was in-hospital mortality. Sensitivity analyses including propensity-score matching adjustments were performed. Mean age of the entire population was 61.8 ± 14.2, and 30.8% were women. There were significant differences in baseline characteristics; notable differences included the older age of patients with ICM (65.1 ± 13.7 vs. 58.2 ± 13.8, P < 0.001), preponderance of males [258 (75.4%) vs. 85 (55.2%), P < 0.001], and higher prevalence of diabetes mellitus [140 (40.9%) vs. 39 (25.3%), P = 0.001] compared with patients in the NICM aetiology group. Patients with ischaemic cardiogenic shock were more likely to have longer shock duration before VA-ECMO implantation (518.7 ± 941.4 min vs. 292.4 ± 707.8 min, P = 0.003) and were less likely to undergo distal limb perfusion than those with NICM [108 (31.6%) vs. 79 (51.3%), P < 0.001]. In-hospital mortality in the overall cohort was 52.2%; patients with ICM had a higher unadjusted risk of in-hospital mortality [203 (59.4%) vs. 56 (36.4%); unadjusted hazard ratio, 2.295; 95% confidence interval, 1.698-3.100; P < 0.001]. There were no significant differences in the primary outcome between the two aetiologies following propensity-score matching multiple adjustments (adjusted hazard ratio, 1.265; 95% confidence interval, 0.840-1.906; P = 0.260). CONCLUSIONS: Results of the current study indicated among patients with cardiogenic shock undergoing VA-ECMO, ischaemic aetiology does not seem to impact in-hospital mortality. These findings underline that early initiation and appropriate treatment strategies of VA-ECMO for patients with ICM shock are required.

Impact of Thrombus Aspiration on Clinical Outcomes in Korean Patients with ST Elevation Myocardial Infarction.

We evaluated whether thrombus aspiration (TA) during primary percutaneous coronary intervention (PCI) reduces adverse clinical outcomes within 30-days and 1-year periods. There is no well-designed, Korean data about the clinical impact of intracoronary TA during primary PCI in patients with ST-segment elevation myocardial infarction (STEMI). From the Korea Acute Myocardial Infarction Registry-National Institute of Health, 3749 patients with STEMI undergoing primary PCI within 12 hours (60.8±12.9 years, 18.7% women) with pre-procedural Thrombolysis in Myocardial Infarction (TIMI) flow 0, 1 in coronary angiography were enrolled between November 2011 and December 2015. The patients were divided into two groups: PCI with TA (n=1630) and PCI alone (n=2119). The primary end-point was major adverse cardiac event (MACE), defined as the composite of cardiovascular death (CVD), recurrent MI and stroke for 30-days and 1-year. TA did not diminish the risk of MACE, all-cause mortality and CVD in all patients during 30-days or 1-year. After performing the propensity score matching, TA also did not reduce the risk of MACE (Hazard ratio (HR) with 95% Confidence Interval (CI):1.187 [0.863-1.633], p value=0.291), all-cause mortality (HR with 95% CI: 1.130 [0.776-1.647], p value=0.523) and CVD (HR with 95% CI: 1.222 [0.778-1.920], p value=0.384) during the 1-year period. In subgroup analysis, there was no benefit of clinical outcomes favoring PCI with TA. In conclusion, primary PCI with TA did not reduce MACE, all-cause mortality or CVD among the Korean patients with STEMI and pre-procedural TIMI flow 0, 1 during the 30-day and 1-year follow ups.

Association of baseline platelet count with all-cause mortality after acute myocardial infarction.

BACKGROUND: We sought to evaluate baseline platelet count as a prognostic indicator in patients with acute myocardial infarction (AMI). METHODS: Data of 13,085 patients with AMI were retrieved from a prospective nationwide AMI registry from November 2011 to December 2015. Using Cox hazards models, cumulative risks for adverse outcomes were compared among patients with baseline platelet count of less than 150 K/µL (lowest quartile), 150 to 249 K/µL, 250 to 349 K/µL (reference) and equal to or greater than 350 K/µL (higher quartile). The primary outcome of interest was all-cause mortality. Secondary outcomes included myocardial infarction, re-hospitalisation for heart failure, and stroke. RESULTS: During a median follow-up of 2.1 years, a steep U-shaped association was observed for the occurrence of all-cause mortality (p for non-linearity <0.001). For stroke, a similar U-shaped curve was also seen (p for non-linearity = 0.095). After multiple adjustments, the lowest and higher quartiles of baseline platelet count were positively associated with all-cause mortality (adjusted hazard ratio: 2.120; 95% confidence interval: 1.345-3.341; p = 0.001, and adjusted hazard ratio: 1.642; 95% confidence interval: 0.957-2.817; p = 0.072, respectively). Similar results were observed in sensitivity analyses even after excluding patients with age ≥75 years or patients with heart failure. CONCLUSIONS: In patients with AMI, baseline platelet count demonstrated a U-shaped association with an increased risk of all-cause mortality at two years. If validated, these findings suggest that baseline platelet count could serve as a preferred prognostic marker in AMI due to its low cost and universal availability.

One-Year Clinical Outcomes between Single- versus Multi-Staged PCI for ST Elevation Myocardial Infarction with Multi-Vessel Coronary Artery Disease: from Korea Acute Myocardial Infarction Registry-National Institute of Health (KAMIR-NIH).

BACKGROUND AND OBJECTIVES: Although complete revascularization is known superior to incomplete revascularization in ST elevation myocardial infarction (STEMI) patients with multi-vessel coronary artery disease (MVCD), there are no definite instructions on the optimal timing of non-culprit lesions percutaneous coronary intervention (PCI). We compared 1-year clinical outcomes between 2 different complete multi-vessel revascularization strategies. METHODS: From the Korea Acute Myocardial Infarction Registry-National Institute of Health, 606 patients with STEMI and MVCD who underwent complete revascularization were enrolled from November 2011 to December 2015. The patients were assigned to multi-vessel single-staged PCI (SS PCI) group (n=254) or multi-vessel multi-staged PCI (MS PCI) group (n=352). Propensity score matched 1-year clinical outcomes were compared between the groups. RESULTS: At one year, MS PCI showed a significantly lower rate of all-cause mortality (hazard ratio [HR], 0.42; 95% confidential interval [CI], 0.19-0.92; p=0.030) compared with SS PCI. In subgroup analysis, all-cause mortality increased in SS PCI with cardiogenic shock (HR, 4.60; 95% CI, 1.54-13.77; p=0.006), age ≥65 years (HR, 4.00; 95% CI, 1.67-9.58, p=0.002), Killip class III/IV (HR, 7.32; 95% CI, 1.68-31.87; p=0.008), and creatinine clearance ≤60 mL/min (HR, 2.81; 95% CI, 1.10-7.18; p=0.031). After propensity score-matching, MS PCI showed a significantly lower risk of major adverse cardiovascular event than SS PCI. CONCLUSIONS: SS PCI was associated with worse clinical outcomes compared with MS PCI. MS PCI for non-infarct-related artery could be a better option for patients with STEMI and MVCD, especially high-risk patients.

Comparison of 1-year clinical outcomes between prasugrel and ticagrelor versus clopidogrel in type 2 diabetes patients with acute myocardial infarction underwent successful percutaneous coronary intervention.

Although the new oral P2Y12 inhibitors, prasugrel/ticagrelor have shown greater efficacy than clopidogrel in patients with the acute coronary syndrome, but they have not shown better efficacy in Korean patients. So we evaluated the efficacy of the prasugrel/ticagrelor in patients with myocardial infarction (MI) and diabetes, a more high-risk patients group.From the Korea Acute Myocardial Infarction Registry-National Institute of Health, 3985 patients with MI and diabetes who underwent PCI were enrolled between November 2011 and December 2015. The patients were divided into 2 groups: clopidogrel (n = 2985) and prasugrel/ticagrelor (n = 1000).After propensity score matching, prasugrel/ticagrelor group showed a no significant difference in risk of the composite of cardiac death (CD), recurrent MI or stroke (hazard ratio [HR], 0.705; 95% confidence interval [CI], 0.474-1.048; P = .084). However, the risk of major bleeding was significantly higher in the prasugrel/ticagrelor group. (HR; 2.114, 95% CI; [1.027-4.353], P = .042). In subgroup analysis, major bleeding was significantly increased in the subgroup of creatinine clearance <60 ml/min/1.73 m, hypertension, underwent a trans-femoral approach and diagnosed as NSTEMI among the prasugrel/ticagrelor group.The use of prasugrel/ticagrelor did not improve the composite of CD, recurrent MI or stroke, however, significantly increased major bleeding events in Korean patients with MI and diabetes undergoing PCI.

Height and sex is strongly associated with radial augmentation index in Korean patients with never-treated hypertension.

OBJECTIVES: Central hemodynamics may better represent the load imposed on the coronary and cerebral arteries and thereby bear a stronger relationship to cardiovascular outcomes. METHODS: Patients who had confirmed hypertension as assessed by daytime 24-hour ambulatory blood pressure monitoring (≥135/85 mmHg) were enrolled. Central blood pressure and radial augmentation index (AIx) corrected for a heart rate of 75 bpm (radial AIx 75) were measured for all patients. We evaluated the association of age, height, and sex with central hemodynamics in patients with never-treated hypertension. RESULTS: A total of 203 patients were enrolled, of whom men numbered 101 (49.7%). The median height of all patients was 162 cm, and mean age was 53.2 years. In the Pearson correlation analysis, regardless of sex difference (R=-0.627 for height, R=0.035 for age, P-value =0.005), a stronger relationship was observed between height and radial AIx 75 than between age and radial AIx 75. In the multiple regression analysis, the sex difference and height were strongly associated with elevated radial AIx 75 in all patients (adjusted R (2)=0.428, ß=6.237, 95% confidence interval [CI] for women 1.480-10.995, P-value =0.011 and ß=-0.632, 95% CI for height -0.929 to -0.335, P-value =0.009, respectively). CONCLUSION: In patients with never-treated hypertension, female sex and shorter height are the important risk factors of elevated radial AIx 75.
