RESUMO
Objective: Bruton tyrosine kinase inhibition in cardiac tissue causes inhibition of the PI3K-AKT signaling pathway, which is responsible for protecting cardiac tissue during stress. Therefore, there is an increase in the risk of arrhythmia. This study explores the prediction of that risk with the Age-Creatinine-Ejection Fraction (ACEF) score as a simple scoring system based on the components of age, creatinine, and ejection fraction. Materials and Methods: Patients diagnosed with chronic lymphocytic leukemia (CLL) and receiving ibrutinib treatment for at least 1 year were evaluated with echocardiography and Holter electrocardiography and the results were compared with a control group of CLL patients who had not received treatment. ACEF score was calculated with the formula age/left ventricular ejection fraction+1 (if creatinine >2.0 mg/dL). Results: When the arrhythmia development of the patients was evaluated, no statistically significant difference was found between the control and ibrutinib groups in terms of types of arrhythmias other than paroxysmal atrial fibrillation (PAF). PAF was found to occur at rates of 8% versus 22% (p=0.042) among ibrutinib non-users versus users. For patients using ibrutinib, an ACEF score of >1.21 predicted the development of PAF with 77% sensitivity and 75% specificity (area under the curve: 0.830, 95% confidence interval: 0.698-0.962, p<0.001). Conclusion: The ACEF score can be used as a risk score that predicts the development of PAF in patients diagnosed with CLL who are scheduled to start ibrutinib.

OBJECTIVE: To investigate the clinical and demographic factors affecting the selection of angiography in patients with severe left ventricular systolic dysfunction (SLVSD, ejection fraction lower than 30%) developing non-ST-segment elevation (NSTEMI). STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: This study was conducted at the Department of Cardiology, School of Medicine, Izmir Katip Celebi University, Izmir, Turkey, between March 2018 and March 2021. METHODOLOGY: Patients with SLVSD (Ejection fraction <30%) developing Clinical and demographic factors were compared between the patients who were or were not decided for angiography. Associated factors for the decision of angiography were evaluated. RESULTS: Overall, 68 (46%) out of 147 patients underwent coronary angiography. Angiography led to coronary artery bypass grafting (CABG) in 14 (21%), percutaneous coronary intervention (PCI) in 30 (44%), and medical treatment in 24 (35%). Among the patients who decided for CABG, 10 (71%) underwent surgery. In multivariate analysis; Killip score ≥2 [Odds ratio (OR) :33.85, 95% Confidence Interval (CI): 5.03-227.405 p<0.001], lower education level (OR: 17.66, 95% CI: 2.25-138.44, p=0.006), anaemia (OR: 10.60, 95% CI: 2.07-54.28, p=0.005), age ≥65 years (OR: 7.124, 95% CI: 1.33-38.12, p=0.02), and PCI history (OR: 0.132, 95% CI: 0.02-0.84, p=0.032) were associated factors with the decision of only medical treatments instead of angiography. CONCLUSION: Demographic factors such as age and education level and clinical factors such as decompensation, PCI history, and anaemia significantly affect the decision of angiography in the patients with SLVSD and NSTEMI. KEY WORDS: Heart failure, NSTEMI, Revascularisation, Severe left ventricular systolic dysfunction, Ejection fraction.

BACKGROUND: The European Society of Cardiology has recently defined heart failure (HF) patient group with a left ventricular ejection fraction (LVEF) of 41-49% as a different category with the term heart failure with mildly reduced ejection fraction (HFmrEF). In this study, we aimed to conduct a research about the correlation between left atrial volume index (LAVI) and atrial fibrillation in patients HFmrEF. METHODS: A total of 282 patients HFmrEF who were admitted to the cardiology department from three different centres were included in the study. The study was planned as multicenter, cross-sectional study. The patients were divided into two groups as sinus rhythm and atrial fibrillation based on their electrocardiographic findings. RESULTS: It was found out that Nt-ProBNP, LA area, LAVI, pulmonary artery pressure, and severe mitral regurgitation rates were significantly higher in the AF group (p < 0.001). ROC analysis resulting in LAVI > 30.5 had 64% sensitivity and 66% specificity in the predicting presence of AF (ROC area under the curve: 0.660, 95% CI: 0.587-0.733, p < 0.001). We also observed that the LA area being >16.55 predicting presence of AF with 60% sensitivity and 58% specificity (ROC area under the curve: 0.624, 95% CI: 0.549-0.699, p = 0.002). CONCLUSION: In the study conducted, we found a correlation between AF and LAVI values in patients in the HFmrEF group. If the LAVI value increases in the follow-up of this group of patients with echocardiography, close follow-up in terms of AF may allow the early control and treatment of AF-related incidents.

BACKGROUND: Coronary artery tortuosity (CAT) is a relatively common finding on coronary angiography and may be associated with impaired left ventricular relaxation and coronary ischemia However, the significance of CAT remains unknown. This study aimed to investigate whether the severity of tortuosity in the targeted coronary segment is a predictor of stent restenosis. METHODS: The study included a total of 637 patients undergoing drug-eluting stent implantation due to stable or unstable angina and who had no native coronary artery stenosis on their last coronary angiogram. The patients were separated into two groups: 312 patients with in-stent restenosis and 325 patients without in-stent restenosis. All patients underwent computed tomography (CT) coronary angiography after invasive angiography and CAT was calculated using the computer software. RESULTS: Patients with in-stent restenosis had higher CAT than those without restenosis (1.25⯱ 0.11 vs. 1.11â¯+ 0.07, pâ¯< 0.001). Multivariate Cox regression analysis showed that the tortuosity index (hazard ratio [HR]: 1.246 95% confidence interval [CI]: 1.127-1.376 pâ¯< 0.001) and the circumflex lesion (HR: 1.437 95% CI: 1.062-1.942 pâ¯= 0.019) were independently associated with in-stent restenosis. With the threshold value of severe tortuosity set at 1.15, the prediction of could be made with 81% sensitivity and 80% specificity. CONCLUSION: The severity of tortuosity is proportional to coronary in-stent stenosis in patients with stable and unstable angina pectoris undergoing drug-eluting stent implantation for a severe single coronary artery.

BACKGROUND: Although the incidence of myocardial bridge (MB) has been defined in different femoral access conventional coronary angiography (FACCA) studies, the frequency of MB on radial access coronary angiography (RACA) is unknown. The aim of this study was to determine the difference in the incidence of MB between patients undergoing RACA and FACCA. METHOD: A total of 2500 consecutive patients who underwent RACA and a total of 1455 consecutive patients who underwent FACCA were retrospectively investigated to detect the presence of MB. The incidences of the groups were calculated separately and compared. The clinical and angiographic features of the patients with MB were analyzed. RESULTS: MB was detected at an incidence of 10.2%, in 255/2500 patients who underwent RACA, and 1.8% in 27/1455 patients who underwent FACCA (p < 0.001). In both RACA and FACCA patients, the most involved coronary artery was the left anterior descending artery (LAD) (86.9% and 93.1%) and the mid-segment (84.9% and 88.9%) was the most affected section. Co-involvement of multiple coronary arteries by MB was 7.8% in patients who underwent RACA and 7.4% in patients who underwent FACCA. Coronary artery disease (CAD) was determined in 111 (35.7%) of the coronary arteries with MB, of which 81.9% were proximal to the MB. No significant CAD was detected in any of the vessels of 69.8% (178/255) of the patients who underwent RACA for different clinical indications. CONCLUSION: These data demonstrated that the incidence of myocardial bridge able to be detected on RACA was much higher than FACCA.

BACKGROUND: Drug-induced atrioventricular block (AVB) is generally considered reversible and does not require a permanent pacemaker implantation (PPM). However, some studies have demonstrated a failure of AVB cessation even when the inducing agent has been discontinued. This study has investigated the use of systemic immune-inflammation index (SII) to predict irreversible drug-induced AVB after drug discontinuation. METHOD: Files of patients with high-degree AVB that required a temporary pacemaker (TPM) were retrospectively analyzed. Sixty-three patients in which AVB was drug-induced were included in the study. The patients were divided into the following two groups: (1) those whose AVB reversed after discontinuation of the related drug, and (2) those in which AVB did not reverse. RESULTS: AVB reversed in 24 patients (38%) after the inducing agent was discontinued while in the remaining 39 patients (62%) PPM was required. The most common drugs to induce AVB were beta-blockers (n = 46, 73%). Follow-up time with TPM was significantly longer in the irreversible group (2.91 ± 1.05 days vs. 4.94 ± 2.15 days, p < .001). Multivariate logistic regression analysis showed that SII (odds ratio [OR] = 1.002; 95% confidence interval [CI] = 1.000-1.003; p = .01) was an independent predictor of the requirement for a PPM. An SII > 752.05 was found to be a predictor of irreversible AVB requiring PPM with a sensitivity of 64% and specificity of 75% (receiving-operating characteristics [ROC] area under the ROC curve [AUC]: 0.704, 95% CI = 0.570-0.838, p = .007). CONCLUSION: Approximately 2/3 of drug-induced high-degree AVBs are irreversible. SII is an easily available and cheap inflammatory biomarker that can be used to predict irreversible AVB.

The treatment process of patients using warfarin is expected to be hindered during the COVID-19 pandemic. Therefore we investigated whether the time in therapeutic range (TTR) and bleeding complications were affected during the COVID-19 pandemic. 355 patients using warfarin were included between March 2019 to March 2021. Demographic parameters, INR (international normalized ratio), and bleeding rates were recorded retrospectively. The TTR value was calculated using Rosendaal's method. The mean age of the patients was 61 ± 12 years and 55% of them were female. The mean TTR value during the COVID-19 pandemic was lower than the pre-COVID-19 period (56 ± 21 vs 68 ± 21, P < 0.001). Among the patients, 41% had a lack of outpatient INR control. During the COVID-19 pandemic, 71 (20%) patients using VKA suffered bleeding. Among patients with bleeding, approximately 60% did not seek medical help and 6% of patients performed self-reduction of the VKA dose. During the COVID-19 pandemic, TTR values have decreased with the lack of monitoring. Furthermore, the majority of patients did not seek medical help even in case of bleeding.

BACKROUND: We aimed to evaluate the utility of the preprocedural platelet-lymphocyte ratio (PLR) for predicting the no-reflow phenomenon after thrombus aspiration during percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). METHOD: We retrospectively analyzed postprocedural thrombolysis in myocardial infarction (TIMI) flow grades and myocardial blush grades (MBG) of 247 patients who underwent a PCI procedure with thrombus aspiration.We divided these patients into two groups according to whether they had no-reflow (TIMI < 3, MBG < 2) or not (TIMI 3, MBG ≥ 2). RESULTS: No-reflow developed in 43 (17%) patients.Preprocedural PLR was significantly higher in the no-reflow group (183.76 ± 56.65 vs 118.32 ± 50.42 p < 0.001).Independent predictors of no-reflow were as follows: higher preprocedural platelet-lymphocyte ratio (PLR) (OR = 1.018; 95% CI = 1.004, 1.033; p = 0.013),mean corpuscular volume (MCV) (OR = 1.118; 95% CI = 1.024, 1.220; p = 0.012) and SYNTAX Score-2 (OR = 1.073; 95% CI = 1.005, 1.146; p = 0.036). PLR of 144 had 79% sensitivity and 75% specificity for the prediction of no-reflow. CONCLUSION: PLR is a reliable predictor for no-reflow in STEMI patients undergoing thrombus aspiration.

An impaired heart rate recovery (HRR) has been associated with increased risk of cardiovascular events, cardiovascular, and all-cause mortality. However, the diagnostic ability of HRR for the presence and severity of coronary artery disease (CAD) has not been clearly elucidated. Our aim was to investigate the relationship between HRR and the SYNTAX (SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery) score in patients with stable CAD (SCAD). A total of 406 patients with an abnormal treadmill exercise test and ≥50% coronary stenosis on coronary angiography were included. The HRR was calculated by subtracting the HR in the first minute of the recovery period from the maximum HR during exercise. The SYNTAX score ≥23 was accepted as high. Correlation of HRR with SYNTAX score and independent predictors of high SYNTAX score were determined. A high SYNTAX score was present in 172 (42%) patients. Mean HRR was lower in patients with a high SYNTAX score (9.8 ± 4.5 vs. 21.3 ± 9, p < 0.001). The SYNTAX score was negatively correlated with HRR (r: -0.580, p < 0.001). In multivariate logistic regression analysis, peripheral arterial disease (OR: 13.3; 95% CI: 3.120-34.520; p < 0.001), decreased HRR (OR: 0.780; 95% CI: 0.674-0.902; p = 0.001), peak systolic blood pressure (OR: 1.054; 95% CI: 1.023-1.087; p = 0.001), and peak HR (OR: 0.950; 95% CI: 0.923-0.977; p < 0.001) were found to be independent predictors of a high SYNTAX score. Our results showed that HRR is significantly correlated with the SYNTAX score, and a decreased HRR is an independent predictor of a high SYNTAX score in patients with SCAD.

Adherence to non-vitamin K antagonist oral anticoagulants (NOACs) is an important factor for ensuring efficacy and safety in nonvalvular atrial fibrillation (NVAF). There are controversial results regarding NOAC adherence in real-world data and there are no data about NOAC adherence in Turkish population. This study investigated the NOAC adherence based on self-report, factors affecting nonadherence, and the relation of the adherence level with efficacy and safety outcomes. This multicenter cross-sectional study included 2738 patients (59% female) using NOAC (dabigatran, apixaban, and rivaroxaban) due to NVAF for more than 3 months with >30 days of supply between September 1, 2015, and February 28, 2016. To measure the adherence level, an 8-item Morisky Medication Adherence Scale was used. The mean age of the patients was 70 ± 10 years. Of the 2738 patients, 44% were receiving dabigatran, 38% rivaroxaban, and 18% apixaban. A total of 630 (23%) patients had high medication adherence, 712 (26%) moderate adherence, and 1396 (51%) low adherence. Nonadherence had related to stroke (5.6% vs 2.5%, P < .001) and minor (21.2% vs 11.1%, P < .001) and major (6.1% vs 3.7%, P = .004) bleeding rates. The adherence to NOAC was found to be quite low in Turkey. Nonadherence is associated with bleeding and thromboembolic cardiovascular events. Age, taking NOAC twice a day, and the additional noncardiac diseases, depression, and dementia were the independent factors affecting poor medication adherence.

Pulmonary embolism (PE) is a potentially life-threatening emergency that is sometimes difficult to diagnose due to nonspecific symptoms and findings. A 69-year-old male was admitted to our hospital with new-onset chest pain and sweating. The electrocardiogram (ECG) revealed sinus rhythm with ST elevations in the inferior leads. His angiogram showed noncritical coronary artery disease with a few plaques. Right heart catheterization was made, which revealed an elevated pulmonary artery pressure of 45/23 mmHg. A pulmonary angiogram was then performed, at first from the pulmonary trunk and then the right pulmonary artery, which showed occlusion of the pulmonary artery to the right lower lobe. This report emphasizes that acute PE should be suspected in every patient with ST elevation myocardial infarction and normal coronary arteries. ST changes may be in the inferior as well as the anterior leads.

Our aim was to evaluate the acute cardiac toxicity of adjuvant trastuzumab treatment and its possible relation to changes in oxidative stress. Electrocardiographic and echocardiographic tissue Doppler imaging (TDI) parameters, activity of antioxidant enzymes (superoxide dismutase; SOD), and products of oxidative stress (malondialdehyde; MDA) were analyzed in 30 patients with early-stage breast cancer who had adjuvant trastuzumab treatment. There was a significant prolongation of QT interval after trastuzumab treatment. There was also a significant decrease in left ventricular ejection fraction (LVEF), TDI-derived S' parameters, and SOD enzyme activity and increase in MDA levels after trastuzumab infusion. There was a positive correlation between changes in SOD activity and LVEF and a negative correlation between changes in MDA levels and LVEF. This study demonstrated a correlation between decreases in LVEF and increases in products of the oxidative stress in patients who had adjuvant trastuzumab treatment.
