We described two patients who were successfully resuscitated from out-of-hospital cardiac arrest. Their ECGs showed ST elevations in V1 and aVR, as well as diffuse ST depression. Their ST elevation in V1 was noted to be greater than in aVR. While one patient was found to have an occlusion of the right ventricular (RV) branch of the right coronary artery, the other was found to have an occlusion of a proximal non-dominant right coronary artery supplying the RV branch. Successful primary percutaneous coronary intervention was performed for each patient with angioplasty and implantation of a drug-eluting stent. Both patients made good physical and neurological recovery.

PURPOSE: We aimed to determine the demographic and epidemiologic variables that are associated with no treatment in lung cancer patients. MATERIALS AND METHODS: Patient data were collected from the Korean National Health Insurance Database. The lung cancer group included patients with an initial diagnosis of lung cancer between January 2009 and December 2014. Treated cases were defined as those that underwent surgery, radiation, or chemotherapy until death, after the diagnosis of lung cancer. Risk of no treatment was calculated by multiple logistic regression analysis. RESULTS: Among the 2,148 new cases of lung cancer from 2009 to 2104, 612 (28.4%) were not treated. Risk of no treatment was higher in the following patients: patients in their 60s (odds ratio [OR], 1.18; 95% confidence interval [CI], 0.75 to 1.84), 70s (OR, 3.64; 95% CI, 2.41 to 5.50), and >80 years old (OR, 16.55; 95% CI, 10.53 to 25.03) than those in their 50s; patients with previous myocardial infarction (OR, 2.07; 95% CI, 1.01 to 4.25) or chronic kidney disease (OR, 2.88; 95% CI, 1.57 to 5.30); and patients diagnosed at a non-referral hospital (OR, 1.40; 95% CI, 1.01 to 1.92) or primary care provider (OR, 1.81; 95% CI, 1.43 to 2.29) compared with referral hospital. Low-income patients receiving Medicaid were 1.75 times (95% CI, 1.14 to 2.68) more likely to forgo treatment than high-income patients (upper 20%). Risk was not associated with sex or the year in which the lung cancer was diagnosed. CONCLUSION: Age predominantly determines whether patients with lung cancer undergo anti-cancer treatment.

BACKGROUND: There is scanty evidence concerning the ability of Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes with Early Implementation of the ACC/AHA Guidelines (CRUSADE) and Acute Catheterization and Urgent Intervention Triage Strategy and Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction (ACUITY-HORIZONS) scores to predict out-of-hospital bleeding risk after percutaneous coronary interventions (PCIs) with drug-eluting stents (DES) in patients receiving dual antiplatelet therapy. We aimed to assess and compare the long-term prognostic value of these scores regarding out-of-hospital bleeding risk in such patients. METHODS: We performed a prospective observational study of 10,724 patients undergoing PCI between January and December 2013 in Fuwai Hospital, China. All patients were followed up for 2 years and evaluated through the Fuwai Hospital Follow-up Center. Major bleeding was defined as Types 2, 3, and 5 according to Bleeding Academic Research Consortium Definition criteria. RESULTS: During a 2-year follow-up, 245 of 9782 patients (2.5%) had major bleeding (MB). CRUSADE (21.00 [12.00, 29.75] vs. 18.00 [11.00, 26.00], P < 0.001) and ACUITY-HORIZONS (9.00 [3.00, 14.00] vs. 6.00 [3.00, 12.00], P < 0.001) risk scores were both significantly higher in the MB than non-MB groups. Both scores showed a moderate predictive value for MB in the whole study cohort (area under the receiver-operating characteristics curve [AUROC], 0.565; 95% confidence interval [CI], 0.529-0.601, P = 0.001; AUROC, 0.566; 95% CI, 0.529-0.603, P < 0.001, respectively) and in the acute coronary syndrome (ACS) subgroup (AUROC: 0.579, 95% CI: 0.531-0.627, P = 0.001; AUROC, 0.591; 95% CI, 0.544-0.638, P < 0.001, respectively). However, neither score was a significant predictor in the non-ACS subgroup (P > 0.05). The value of CRUSADE and ACUITY-HORIZONS scores did not differ significantly (P > 0.05) in the whole cohort, ACS subgroup, or non-ACS subgroup. CONCLUSIONS CRUSADE and ACUITY-HORIZONS scores showed statistically significant but relatively limited long-term prognostic value for out-of-hospital MB after PCI with DES in a cohort of Chinese patients. The value of CRUSADE and ACUITY-HORIZONS scores did not differ significantly (P > 0.05) in the whole cohort, ACS subgroup, or non-ACS subgroup.

PURPOSE: Calcium channel blockers diltiazem and nitrate have been used as selective coronary vasodilators for patients with significant coronary artery spasm (CAS). However, no study has compared the efficacy of diltiazem alone versus diltiazem with nitrate for long-term clinical outcomes in patients with CAS. MATERIALS AND METHODS: A total of 2741 consecutive patients without significant coronary artery disease with positive CAS by acetylcholine (Ach) provocation test between November 2004 and May 2014 were enrolled. Significant CAS was defined as a narrowing of >70% by incremental intracoronary injection of 20, 50, and 100 µg of Ach into the left coronary artery. Patients were assigned to either the diltiazem group (n=842) or the dual group (diltiazem with nitrate, n=1899) at physician discretion. To adjust for potential confounders, a propensity score matching (PSM) analysis was performed using the logistic regression model. After PSM analysis, two well-balanced groups (811 pairs, n=1622, C-statistic=0.708) were generated. RESULTS: At 5 years, there were similar incidences in primary endpoints, including mortality, myocardial infarction, revascularization, and recurrent angina requiring repeat coronary angiography between the two groups. Diltiazem alone was not an independent predictor for major adverse cardiovascular events or recurrent angina requiring repeat coronary angiography. CONCLUSION: Despite the expected improvement of endothelial function and the relief of CAS, the combination of diltiazem and nitrate treatment was not superior to diltiazem alone in reducing mortality and cardiovascular events up to 5 years in patients with significant CAS.

BACKGROUND/AIMS: Angiotensin II type 1 receptor blockers (ARBs) have not been adequately evaluated in patients without left ventricular (LV) dysfunction or heart failure after acute myocardial infarction (AMI). METHODS: Between November 2005 and January 2008, 6,781 patients who were not receiving angiotensin-converting enzyme inhibitors (ACEIs) or ARBs were selected from the Korean AMI Registry. The primary endpoints were 12-month major adverse cardiac events (MACEs) including death and recurrent AMI. RESULTS: Seventy percent of the patients were Killip class 1 and had a LV ejection fraction > or = 40%. The prescription rate of ARBs was 12.2%. For each patient, a propensity score, indicating the likelihood of using ARBs during hospitalization or at discharge, was calculated using a non-parsimonious multivariable logistic regression model, and was used to match the patients 1:4, yielding 715 ARB users versus 2,860 ACEI users. The effect of ARBs on in-hospital mortality and 12-month MACE occurrence was assessed using matched logistic and Cox regression models. Compared with ACEIs, ARBs significantly reduced in-hospital mortality(1.3% vs. 3.3%; hazard ratio [HR], 0.379; 95% confidence interval [CI], 0.190 to0.756; p = 0.006) and 12-month MACE occurrence (4.6% vs. 6.9%; HR, 0.661; 95% CI, 0.457 to 0.956; p = 0.028). However, the benefit of ARBs on 12-month mortality compared with ACEIs was marginal (4.3% vs. 6.2%; HR, 0.684; 95% CI, 0.467 to 1.002; p = 0.051). CONCLUSIONS: Our results suggest that ARBs are not inferior to, and may actually be better than ACEIs in Korean patients with AMI.

BACKGROUND/AIMS: This meta-analysis compared the effects of amlodipine besylate, a charged dihydropyridine-type calcium channel blocker (CCB), with other non-CCB antihypertensive therapies regarding the cardiovascular outcome. METHODS: Data from seven long-term outcome trials comparing the cardiovascular outcomes of an amlodipine-based regimen with other active regimens were pooled and analyzed. RESULTS: The risk of myocardial infarction was significantly decreased with an amlodipine-based regimen compared with a non-CCB-based regimen (odds ratio [OR], 0.91; 95% confidence interval [CI], 0.84 to 0.99; p = 0.03). The risk of stroke was also significantly decreased (OR, 0.84; 95% CI, 0.79 to 0.90; p < 0.00001). The risk of heart failure increased slightly with marginal significance for an amlodipine-based regimen compared with a non-CCB-based regimen (OR, 1.14; 95% CI, 0.98 to 1.31; p = 0.08). However, when compared overall with beta-blockers and diuretics, amlodipine showed a comparable risk. Amlodipine-based regimens demonstrated a 10% risk reduction in overall cardiovascular events (OR, 0.90; 95% CI, 0.82 to 0.99; p = 0.02) and total mortality (OR, 0.95; 95% CI, 0.91 to 0.99; p = 0.01). CONCLUSIONS: Amlodipine reduced the risk of total cardiovascular events as well as all-cause mortality compared with non-CCB-based regimens, indicating its benefit for high-risk cardiac patients.

OBJECTIVETo improve the awareness of acute coronary artery thrombosis in Kawasaki disease (KD).

METHODSix KD patients with acute coronary artery thrombosis (Jan. 2004 to Jan. 2013) were studied retrospectively. The basic information, clinical manifestations, laboratory data, echocardiography and electrocardiography (ECG), method and consequence of thrombolytic therapy were analyzed.

RESULTThe mean age of patients with coronary artery thrombosis (5 males and 1 female) was (17.2 ± 11.3) months.Five cases had thrombosis in left coronary artery (LCA), and four cases had thrombosis in aneurysm of left anterior descending artery (LAD). One case had thrombosis in both left and right coronary artery (RCA).One case died. Maximum thrombus was about 1.60 cm × 0.80 cm, locating in LAD. The diameter of LCA and RCA was (0.44 ± 0.07) cm and (0.45 ± 0.07) cm. Two patients showed abnormal ECG. Case 3 showed ST segment depression in lead V5. Case 6 showed myocardial infarction.In acute phase of KD, three patients received treatment with intravenous immunoglobin (IVIG), five patients were treated with aspirin.In sub-acute and convalescent phase of KD, all patients were treated with low-dose aspirin.Warfarin and dipyridamole were applied in 5 patients. All cases were treated with thrombolytic therapy using urokinase and/or heparin. After thrombolytic therapy, echocardiography showed thrombolysis in four cases and no change in one.One patient died of myocardial infarction.

CONCLUSIONMost of acute coronary thrombosis in KD occurred in LAD. KD patients with coronary artery thrombosis are at risk of sudden death due to myocardial infarction.

As the first nationwide Korean prospective multicenter data collection registry, the Korea Acute Myocardial Infarction Registry (KAMIR) launched in November 2005. Through a number of innovative approaches, KAMIR suggested new horizons about acute myocardial infarction (AMI) which contains unique features of Asian patients from baseline characteristics to treatment strategy. Obesity paradox was existed in Korean AMI patients, whereas no gender differences among them. KAMIR score suggested new risk stratifying method with increased convenience and an enhanced accuracy for the prediction of adverse outcomes. Standard loading dose of clopidogrel was enough for Asian AMI patients. Triple antiplatelet therapy with aspirin, clopidogrel and cilostazol could improve clinical outcomes than dual antiplatelet therapy with aspirin and clopidogrel. Statin improved clinical outcomes even in AMI patients with very low LDL-C levels. The rate of percutaneous coronary intervention was higher and door-to-balloon time was shorter than the previous reports. Zotarolimus eluting stents as the 2nd generation drug-eluting stent (DES) was not superior to the 1st generation DES, in contrast to the western AMI studies. KAMIR made a cornerstone in the study of Korean AMI and expected to be new standards of care for AMI with the renewal of KAMIR design to overcome its pitfalls.
