RESUMEN
The CHA2DS2-VASc (congestive heart failure, hypertension, age, diabetes mellitus, stroke, vascular disease, sex) scoring system, which includes conventional risk factors of coronary artery disease, was originally created to quantify the risk of thromboembolism in patients with atrial fibrillation. This study evaluated the usefulness of this score to predict adverse outcomes in STEMI (ST-elevation myocardial infarction) patients without atrial fibrillation. Primary end points were identified as MACE (major adverse cardiovascular events) which included in-hospital death or cerebrovascular accident. MACE rate was 10% (193 patients). The CHA2DS2-VASc score was an independent predictor of MACE (95% CI, 2.31 [1.37-3.9]; P = .0016). Other independent predictors of MACE included heart rate (95% CI, 1.56 [0.97-2.50]; P = .0242), admission Killip class (95% CI, 24.19 [10.74-54.46]; P < .0001), admission creatinine level (95% CI, 1.54 [1.10-2.16]; P = .0024), peak CK-MB level (95% CI, 1.63 [0.98-2.70]; P = .0001), and no-reflow (95% CI, 2.45 [1.25-4.80]; P = .0085). A nomogram was developed to estimate the risk of in-hospital adverse outcomes for STEMI patients. The CHA2DS2-VASc score was an independent predictor of MACE in STEMI patients. Linear analysis of CHA2DS2-VASc score without dichotomization was the main difference of this study from others.
RESUMEN
OBJECTIVES: Pulmonary embolism (PE) is one of the leading causes of cardiovascular mortality worldwide. Electrocardiography (ECG) may provide useful information for patients with acute PE. In this study, we aimed to investigate the diagnostic value of the QRS duration and RS time in inferolateral leads in patients admitted to the emergency department, and pre-diagnosed with acute PE. METHODS: We retrospectively enrolled 136 consecutive patients, admitted to the emergency department, pre-diagnosed with the clinical suspicion of acute PE, and underwent computerized tomographic pulmonary angiography (CTPA) to confirm the PE diagnosis. The study subjects were divided into two groups according to the presence or absence of PE, and the independent predictors of PE were investigated. RESULTS: Sixty-eight patients (50%) had PE. Patients with PE had a longer RS time. Among the ECG parameters, only RS time was an independent predictor of PE (OR: 1.397, 95% CI: 1.171-1.667; pâ¯<â¯0.001). The ROC curve analyses revealed that the cut-off value of RS time for predicting acute PE was 64.20â¯ms with a sensitivity of 85.3% and a specificity of 79.4% (AUC: 0.846, 95%CI: 0.749-0.944; pâ¯<â¯0.001). In the correlation analyses; the RS time was correlated with RV end-diastolic diameter (râ¯=â¯0.422; pâ¯<â¯0.001), RV/left ventricle (LV) ratio (râ¯=â¯0.622; pâ¯<â¯0.001), and systolic pulmonary artery pressure (SPAP) (râ¯=â¯0.508; pâ¯<â¯0.001). CONCLUSION: As a novel ECG parameter, RS time could be measured for each patient. A longer RS time can be a very useful index for diagnosing acute PE as well as for estimating the RV end-diastolic diameter and SPAP.

BACKGROUND: Atrial fibrillation is the most common clinically significant arrhythmia. It is now established that atrial high-rate episodes are highly correlated with atrial fibrillation. AIMS: To investigate the relation between diastolic electrocardiographic parameters and subclinical atrial fibrillation detected by cardiac implantable electronic devices. STUDY DESIGN: Ccross-sectional study. METHODS: A total of 203 patients who had a dual-chamber, rate-modulated pacing pacemaker implanted due to sinus node dysfunction were prospectively enrolled in this study. Atrial high-rate episodes were defined as any lasting more than 5 min with an atrial rate of ≥220 beats per minute during the previous year. Patient groups were categorized on the basis of pacemaker interrogation as the absence of atrial high-rate episodes [atrial high-rate episodes (-)] and the presence of atrial high-rate episodes [atrial high-rate episodes (+)]. Episodes related to atrial over sensing were excluded. Twelve-lead surface electrocardiography was independently analyzed by two experienced readers for the measurement of diastolic electrocardiography parameters. RESULTS: Among 203 patients (mean age: 67.5±9.1, 60.1% male), 51 (25.1%) with atrial high-rate episodes were defined as group 1 and 152 (74.9%) without atrial high-rate episodes were defined as group 2. Both groups were similar in terms of demographic characteristics and cardiovascular risk factors. Tend-Q and Tend-P were significantly longer in group 2. PQ interval was statistically longer in group 1. Corrected QT interval was significantly longer in group 1. Diastolic electrocardiography index, heart rate and PQ and QT intervals were the only independent predictors of atrial high-rate episodes in patients with dual pacemakers in multivariate analysis. CONCLUSION: Abnormal diastolic electrocardiography parameters are powerful predisposing factors for the initiation of incident atrial fibrillation. Diastolic electrocardiography parameters and a novel diastolic index predict atrial high-rate episodes. Evaluating these parameters enables clinicians to identify patients who are at high risk and who may benefit from prophylactic treatment.

We evaluated whether primary percutaneous coronary intervention (pPCI) during off-hours is related to an increased incidence of contrast-induced nephropathy (CIN). We retrospectively analyzed the incidence of CIN mortality among 2552 patients with consecutive ST-segment elevation myocardial infarction treated with pPCI during regular hours (weekdays 8:00 am to 5:00 pm) and off-hours (weekdays 5:01 pm to 7:59 am, weekends and holidays). Patients in the off-hour group were more frequently admitted with acute heart failure symptoms (16.4% vs 7.8%, P < .001) and more contrast was injected during the procedure (235.2 ± 82.3 vs 248.9 ± 87.1 mL, P = .002). The frequency of CIN between on-hour and off-hour groups was similar (7.1% vs 6.2%, P = .453), but there was a trend toward higher in-hospital mortality when pPCI was performed during off-hours (1.9% vs 0.7%, P = .081). Off-hour pPCI was not associated with an increased risk of CIN (odds ratio: 1.051, P = .833). The incidence of CIN did not increase during off-hours, and off-hour pPCI is not a risk factor for CIN, despite an apparent increase in contrast media use during off-hour pPCI.

We aimed to investigate the relationship between platelet-to-lymphocyte ratio (PLR) and contrast-induced acute kidney injury (CI-AKI) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). A total of 2563 patients diagnosed with STEMI and underwent primary pPCI were retrospectively included in the study. Levels of PLR and creatinine were measured before and at 72 hours after pPCI. Patients were divided into 2 groups: non-CI-AKI group and CI-AKI group. Contrast-induced acute kidney injury occurred in 6.4% of the overall study population. Patients in the CI-AKI group had significantly higher PLR than those in the non-CI-AKI group (169.18 ± 81.01 vs 149.49 ± 74.54, P < .001). In logistic regression analysis, PLR was an independent predictor of CI-AKI (odds ratio [OR]: 1.774, 95% CI: 1.243-2.532, P = .002), along with age, use of angiotensin-converting enzyme inhibitor/angiotensin receptor blocker prior to the procedure, preprocedural creatinine level, amount of contrast material used during the procedure, and hypertension. Increased PLR levels are independently associated with a greater risk of CI-AKI in patients undergoing primary PCI for STEMI.

AIM: Octogenarian patients have higher mortality and morbidity rates after acute coronary syndromes. Risk factors for in-hospital mortality in the primary percutaneous coronary intervention (PCI) era were underrepresented in previous studies. In the present study, we aimed to assess the risk factors of in-hospital mortality after primary PCI in this population. METHODS: We analyzed 2353 patients who underwent primary PCI after ST segment elevated myocardial infarction (STEMI). Patients were divided into two groups according to aged: ≥80 years (octogenarian) and <80 years (control). Risk factors for in-hospital mortality were analyzed in the whole group and octogenarian patients. RESULTS: We found that octogenarians have 10.6-fold higher mortality risk after STEMI. After a univariate and multivariate analysis, acute stent thrombosis was the most explicit risk factor for in-hospital mortality in the octogenarian group (OR 21.13, 95% CI 2.11-102.76, P < 0.001). Additionally, anterior myocardial infarction (OR 4.90, 95% CI 1.90-22.10, P = 0.04), ventricular arrhythmias (OR 15.64, 95% CI 2.81-87.12, P = 0.002), multivessel disease (OR 6.5, 95% CI 1.11-38.85, P = 0.04), ejection fraction <30% (OR 1.24, 95% CI 0.26-6.00, P = 0.04) and KILLIP score ≥2 (OR 1.20, 95% CI 0.20- 7.41, P = 0.01) were also significantly associated with mortality. CONCLUSIONS: Acute stent thrombosis, anterior MI, heart failure, low ejection fraction, ventricular arrhythmias and multivessel disease are the independent risk factors for in-hospital mortality among octogenarian patients after primary PCI. Geriatr Gerontol Int 2017; 17: 584-590.

BACKGROUND AND AIM OF THE STUDY: The neutrophil-tolymphocyte ratio (NLR) was found to be a predictor of adverse outcome in patients with coronary artery disease (CAD). The ratio may also be a useful marker to predict mortality following valve replacement surgery. METHODS: A total of 932 patients was enrolled retrospectively. Patients were allocated to three tertiles based on their NLR (group 1, NLR ≤1.90; group 2, 1.90 < NLR ≤2.93; group 3, NLR >2.93). RESULTS: Patients in the highest tertile were older (p = 0.049, 95% CI 0.09-5.98), tended to have chronic renal failure (p = 0.028, OR: 2.6, 95% CI 1.08-6.35), and had more frequent critical CAD on preoperative angiography (p <0.001, OR 2.1, 95% CI 1.38-3.21). Postoperatively, patients in the highest NLR tertile had a higher in-hospital mortality rate than those in the first tertile (p <0.001, OR 4.67, 95% CI 2.37-9.20) and second tertile (p = 0.002, OR 2.26, 95% CI 1.32-3.86). Patients in the third tertile had the highest mortality at day 300 (log-rank p <0.001). The hazard ratio (HR) for the second tertile was 1.8 (p = 0.11, 95% CI 0.88-3.79), and for the third tertile was 2.8 (p = 0.003, 95% CI 1.40-5.59). CONCLUSIONS: The NLR is a useful parameter to assess postoperative in-hospital mortality risk after valvular surgery.

OBJECTIVE: We aimed to assess the risk factors for coronary artery ectasia (CAE) as infarct-related artery (IRA) and short-term and 1 year outcomes. BACKGROUNDS: CAE in patients with ST elevated myocardial infarction (STEMI) is a rare condition with a limited knowledge about the risk factors associated with coronary artery ectasia in STEMI and prognosis after primary percutaneous coronary interventions. METHODS: Retrospectively, 1655 patients with STEMI who were undergone coronary angiography were included in this study. Patients were divided into two groups according to their coronary anatomy as ectasia and control groups. Demographic features, angiographic results, and clinical events were compared. Multivariate analysis was performed to assess the association of the features with CAE in STEMI. RESULTS: In total, 1655 patients (99 patients in CAE group vs 1556 patients in control group) were analyzed. Hypertension and smoking were significantly higher in CAE group. No-reflow rates were significantly higher (13.1% vs 5.4%, p = 0.004) in CAE group. In-hospital mortality rates were similar between the groups. Difference in revascularization rates (8.1% vs 9.6%, p = 0.39) and death in 1 year (6.1% vs 4.9%, p = 0.37) were also nonsignificant between the groups. According to results of the multivariate analysis, hypertension (Odds ratio (OR): 1.71 (1.14-2.58), p = 0.01) and smoking (OR: 1.98 (1.32-2.99), p = 0.001) remained significantly associated with coronary ectasia. CONCLUSION: In conclusion, despite being higher no-reflow rates, short-term and 1 year survival and revascularization rates were similar between the groups. Additionally, hypertension and smoking were associated with CAE as IRA. © 2016 Wiley Periodicals, Inc.

Thrombosis and distal embolization play crucial role in the etiology of no-reflow. CHA2DS2-VASc score is used to estimate the risk of thromboembolism in patients with atrial fibrillation. We tested the hypothesis that CHA2DS2-VASc can predict no-reflow among patients who underwent primary percutaneous coronary intervention (PCI). A total number of 2375 consecutive patients with ST-segment elevation myocardial infarction were assessed for the study. Patients were divided into 2 groups as no-reflow (n = 111) and control (n = 1670) groups according to post-PCI no-reflow status. CHA2DS2-VASc scores were calculated for all patients. CHA2DS2-VASc scores were significantly higher in the no-reflow group compared to the control group. After a multivariate regression analysis, CHA2DS2-VASc score remained as an independent predictor (odds ratio: 1.58, 95% confidence interval: 1.33-1,88, P < .001) of no-reflow. Receiver-operating characteristics analysis revealed the cutoff value of CHA2DS2-VASc score ≥2 as a predictor of no-reflow with a sensitivity of 66% and a specificity of 59%. Moreover, in-hospital mortality was also associated with significantly higher CHA2DS2-VASc scores. In conclusion, CHA2DS2-VASc score is associated with higher risk of no-reflow and in-hospital mortality rates in patients who underwent primary PCI.

Pulmonary embolism (PE) is a major cause of cardiovascular death. Thrombolytic therapy was shown to reduce mortality, especially in high risk patients. In elderly patients (>65 years old) with PE, thrombolytic therapy may be underused due to risk of hemorrhagic complications. In this study, we aimed to assess the effectiveness and safety of thrombolytic therapy among elderly patients with PE. 363 patients (205 subjects in study group, 158 subjects in control group) who were admitted to our hospital with PE were enrolled to the study. The patients were divided into subgroups according to their age and treatment strategy. Mortality rates and bleeding complications according to TIMI bleeding criteria in 30 days and 1-year were analyzed. In elderly patients, total mortality (7.8 vs. 20.1 %, p = 0.05) and mortality at 1-year follow-up (1.9 vs. 12.9 %, p = 0.03) was significantly lower in patients who received thrombolytic treatment. Difference in total bleeding (9.8 vs. 4.5 %, p = 0.18) and major bleeding (3.9 vs. 0.6 %, p = 0.10) in thrombolytic and non-thrombolytic groups was non-significant. Thrombolytic therapy is associated with lower mortality and acceptable bleeding complication rates in PE patients older than 65 years old.

Marijuana (cannabis) is a frequently used recreational drug that potentially imposes serious health problems. We present a case of acute myocardial infarction with chronic total occlusion of left main coronary artery due to marijuana smoking in a 27-year-old man, which was not previously reported. This case illustrate that marijuana abuse can lead to serious cardiovascular events.
