The frontal QRS-T (fQRST) angle is associated with worse cardiovascular outcome. The study aimed to assess the effect of reverse dipping pattern on f(QRST) angle in newly diagnosed masked hypertens...
Background: Electrical cardioversion (ECV) is a technique used to restore sinus rhythm in atrial fibrillation (AF), aiming to reduce AF‐related symptoms. Various recurrence predictors, such as non‐paroxysmal pattern, prolonged duration, chronic obstructive pulmonary disease, advanced age, or left atrial dilation, have been identified. Hence, the aim of our study was to determine the parameters that could predict AF recurrence in the long term in patients who underwent ECV. Methods: One hundred seventy‐two patients who underwent electrical cardioversion due to AF at our tertiary center were included in the study. Patients with recurrent AF after cardioversion were defined as the AF recurrence (+) group, and those with normal sinus rhythm were defined as the AF recurrence (−) group. Parameters that would predict AF recurrence were investigated between these two groups. Results: AF recurrence was observed in 91 patients, while 81 patients did not experience any recurrence. The prediction model, constructed using multivariate Cox regression analysis, included six variables: non‐ high‐density lipoprotein (HDL) cholesterol, free T3, mean corpuscular volume (MCV), left atrium anterior–posterior diameter, number of cardioversions, and oral anticoagulant use. ROC curve analysis demonstrated that our prediction model effectively distinguished between patients with arrhythmia relapse and those without, with an AUC value of 0.719 ( p < .05). Conclusions: This study revealed that AF recurrence after ECV can be predicted by our prediction model consisting of patient characteristics, disease factors, and various biochemical parameters. The current study demonstrated a statistically significant association between the number of cardioversions and non‐HDL cholesterol levels in patients with recurrent AF.
Objectives: Our aim was to investigate whether admission advanced lung cancer inflammation index (ALI) values have a prognostic role on one-year major adverse cardiovascular and cerebrovascular events (MACCEs) in non-ST elevation myocardial infarction (NSTEMI) patients undergoing percutaneous coronary intervention (PCI). Methods: Our study consisted of 1173 consecutive patients aged 61.9 ± 12.5 years. The study population was divided into two groups according to the occurrence of MACCEs. BMI (body mass index), serum albumin levels and NLR (neutrophil to lymphocyte ratio) of patients were collected from hospital records, and ALI was calculated based on the following formula: BMI × serum albumin/NLR. We also calculated neutrophil to lymphocyte ratio (NLR), C-reactive protein/albumin ratio (CAR) and uric acid to albumin ratio (UAR) and investigated the association of these inflammation-based biomarkers with one-year MACCEs. Results: During the 12-month follow-up period, 158 (13.5%) patients had MACCEs, 55 (4.7%) of whom had all-cause mortality, 96 (8.2%) had nonfatal MI and 7 (0.6%) had nonfatal stroke. Patients with MACCEs had significantly lower ALI (p < 0.001), and also ALI (area under the curve [AUC] = 0.658, p < 0.001) had better discriminatory power and predictive accuracy in determining one-year MACCEs compared to albumin (AUC = 0.594, p < 0.001), NLR (AUC = 0.631, p < 0.001), CAR (AUC = 0.595, p < 0.001) and UAR (AUC = 0.577, p = 0.001) in the ROC analysis. Individuals with an ALI value lower than 43.9 were at greater risk of developing MACCEs (p < 0.001) due to the Delong test. Conclusions: Determining the level of ALI may have the potential to improve risk prognostication in NSTEMI patients undergoing revascularization therapy.

Heart failure patients with reduced ejection fraction are at high risk for ventricular arrhythmias and sudden cardiac death. Ivabradine, a specific inhibitor of the If current in the sinoatrial node, provides heart rate reduction in sinus rhythm and angina control in chronic coronary syndromes.
