ABSTRACT
OBJECTIVE: Despite their effectiveness, cardiac rehabilitation (CR) programs have low participation and adherence rates. CR participation and adherence are directly related to the social, economic, cultural, and geographical characteristics of the society. Therefore, our study aimed to investigate the reasons behind low participation in CR within Turkish society, as well as the barriers that restrict participation despite educational efforts. METHOD: The research was conducted with participants who were over 18 years of age, had any history of heart disease, and had been hospitalized in the last year. The patients' medical history, chronic diseases, demographics, habits, employment and income status, educational status, and approaches to CR were surveyed. Additionally, patients who still did not consider participating in CR after receiving information were asked about the reasons for their decisions. RESULTS: Although 95.6% of patients were eligible for CR, 91.9% of them were previously unaware of this treatment option. After being informed, 29.4% of patients agreed to participate in CR. The most common reasons for not participating after receiving information were as follows: three days a week is too much (21.9%); this place is far away, but if it were closer, I would come (18.1%); I can't come on weekdays (15.6%); and I would come if someone brought me (14.4%). CONCLUSION: We observed that the participation rate in CR increased from 0% to 29.4% after receiving information. Furthermore, it was determined that the CR schedule and transportation were significant factors influencing participation.
ABSTRACT
BACKGROUND: The available evidence on the impact of altitude training on sports performance is inconclusive. Heart rate variability (HRV) and heart rate recovery (HRR) are among the most frequently used parameters in athletic performance analysis and monitoring. Our study aims to investigate the effect of high altitude training on HRR and HRV, which are reliable predictors of athletic performance. METHODS: Elite national swimmers were included in the study. Time domain and frequency domain analyzes were performed with the Polar Verity Sense device and Kubios HRV software. HRR were measured at one-minute intervals for the first 15 minutes after peak heart rate, and then recorded at the 20th, 25th and 30th minutes. RESULTS: A significant difference is observed from the beginning to the 11th minute. The P value at 1, 3, 5, 7 and 11 minutes is 0.001, 0.023, 0.032, 0.019 and 0.020, respectively. Similarly, a significant change was observed in delta HRR. Among the HRV parameters, RMSSD, SDNN, Poincaré SD1 and PNS are statistically significant. P values are 0.004, 0.018, 0.024 and 0.013 respectively. CONCLUSIONS: High altitude training program has a positive effect on HRV and CRV in elite swimmers. This condition is associated with increased cardiac parasympathetic activity. Time domain analyses have proven to be more beneficial for HRV. HRR and HRV are effective, reliable and inexpensive methods of performance monitoring of elite athletes.
ABSTRACT
OBJECTIVE: Individuals across all age groups may experience elevated blood pressure due to a combination of internal and environmental factors. Factors influencing arterial pressure include diet, stress, sleep patterns, and lifestyle. This study aims to investigate the susceptibility to high blood pressure among occupational groups working night shifts. METHOD: The study included healthcare worker participants who had at least six night shifts per month. A control group consisted of participants performing the same roles during daytime. Participants with chronic diseases or those taking blood pressure-affecting medication were excluded. Holter recordings were made over a minimum of 48 hours, including both a free day and a work day. RESULTS: The study involved 114 participants-55 in the study group and 59 in the control group. Statistically significant differences were noted between the groups in the daylight-night ratios of systolic and diastolic pressures, with P values of 0.006 and 0.005, respectively. The systolic daylight-night difference was -5.7 ± 5.5% in the study group and -9.0 ± 7.0% in the control group. The diastolic daylight-night difference was -7.9 ± 9.6% in the study group and -12.7 ± 8.2% in the control group. CONCLUSION: Occupations with nighttime work schedules are often associated with non-dipping blood pressure patterns due to sleep disturbances. It is crucial to consider the blunted dipping of blood pressure induced by night shift work when assessing and monitoring hypertension and related medical conditions.

Coronary artery anomalies (CAAs) are rare, but they can cause serious consequences, complicate the diagnosis of coronary artery disease (CAD), and hamper the ability of the physician to perform the correct intervention for patients with CAD. The widespread use of coronary computed tomography and angiography has shown that the incidence is higher than previously thought. CAAs can occur with various anatomical features. We present three rare examples. The first example involves a circumflex artery (CX) that originates from a different ostium on the right side, despite the presence of left arteries in normal anatomical structures. The second case involves an accessory CX originating from the right coronary artery (RCA) ostium, despite the CX origin being in the left cusp. Finally, the third case involves an accessory left anterior descending artery (LAD) originating from the RCA ostium, despite the LAD origin being in the left cusp. There were no high-risk features in all three cases, and no symptoms were observed during follow-up with the patients. The occurrence of these cases is exceptional and may be overlooked; hence, their identification has significance.
ABSTRACT
If a permanent pacemaker lead is misplaced in the left ventricle (LV), the lead may interfere with normal functioning of the heart leading various complications, including heart rhythm problems and blood clots. In our case, the LV lead that passed through the patent foramen ovale and was misplaced into the LV was detected in a 78-year-old patient who presented with embolic stroke. Thrombus regression was achieved with anticoagulation, and then the lead extraction was planned. The lead extraction is a priority in acute cases; but it is not the primary approach in long-term leads that were misplaced into the LV. A patient-based individual approach should be preferred in such cases.

Kounis syndrome is a rare type of acute coronary syndrome (ACS) that occurs as a result of an allergic or anaphylactic reaction. Kounis syndrome can be induced by various medications including antibiotics, proton pump inhibitors, antihypertensive medications, corticosteroids, and antineoplastic medications. Additionally, cases of Kounis syndrome associated with lansoprazole and pantoprazole have been previously reported in the literature. In this report, we present a case of Kounis syndrome associated with omeprazole use, and discuss the need for a high index of suspicion as it is often underrecognised.

Corynebacterium striatum is considered a rare pathogen in infective endocarditis (IE). C. striatum is a Gram-positive facultative anaerobic bacterium found in the environment and human flora. It is part of the microbiota of the skin and nasal mucosa of humans and has been increasingly reported as the etiologic agent of community-acquired and nosocomial diseases. A 91-year-old female patient was admitted to our clinic with complaints of increased fatigue for a week. Transthoracic echocardiography revealed a labile, echogenic appearance on the mitral valve that may be consistent with infective endocarditis, causing mitral regurgitation. Transesophageal echocardiography (TEE) confirmed this finding on the same day. In three-dimensional (3D) TEE, there was an oval mass of 1.9 cm × 1.1 cm at the level of the P2 scallop of the posterior mitral leaflet, and 1.0 cm of mobile vegetation was observed on it. Three serial blood cultures from peripheral vessels identified C. striatum. Antibiotic treatment of the patient was started with daptomycin 1 × 750 mg and meropenem 3 × 1 g. The cardiology team advised the patient to undergo early surgery, but the patient declined, and the case was followed up medically. On the 10th follow-up day, the patient had a speech disorder. Cerebral computed tomographic angiography showed an appearance compatible with a septic embolism in the left main cerebral artery. The patient's condition worsened throughout follow-ups, and she died on day 12. The purpose of presenting this case is to emphasize the importance of Corynebacterium species, which is a cause of rare native valve infectious endocarditis, and to show the difficulties in its treatment.
ABSTRACT
BACKGROUND: Electrocardiographic parameters, such as P wave peak time (PWPT), P wave duration (PWD), and P wave amplitude in lead DI, have been utilized to assess left atrial anomalies linked to the development of atrial fibrillation (AF) in different cohort settings. OBJECTIVE: To compare electrocardiographic parameters, such as P waves, in predicting long-term AF risk in acute ischemic stroke cases. METHODS: The data of 231 consecutive acute ischemic stroke cases were retrospectively collected. Two independent cardiologists interpreted the electrocardiography recordings for PWPT, PWD, and P wave amplitude in lead DI. The median follow-up study period was 16 (interquartile range [IQR]: 11-24) months. RESULTS: In total, AF was detected in 43 (18.6%) cases. All studied P wave parameters were found to be statistically significant in cases with AF. Based on multivariable logistic regression analysis, dementia, left atrium volume index, PWD (razão de chances [RC]: 1.11; 95% confidence interval [CI]: 1.058-1.184; p = 0.003), PWPT in lead DII (RC: 1.030; 95%CI: 1.010-1.050; p = 0.003), and advanced interatrial block morphology were independent predictors of long-term AF. P wave duration had the highest area under the curve value, sensitivity, and specificity for long-term AF in such cases compared with the other P wave parameters. CONCLUSIONS: Our head-to-head comparison of well-known P wave parameters demonstrated that PWD might be the most useful P wave parameter for long-term AF in acute ischemic stroke cases.
ANTECEDENTES: Parâmetros eletrocardiográficos, como tempo de pico da onda P (PWPT, na sigla em inglês), duração da onda P (PWD, na sigla em inglês) e amplitude da onda P na derivação DI, têm sido utilizados para avaliar anomalias atriais esquerdas ligadas ao desenvolvimento de fibrilação atrial (FA) em diferentes cenários de coortes. OBJETIVO: Comparar os parâmetros eletrocardiográficos destas ondas P na predição do risco de FA de longo prazo em casos de acidente vascular cerebral (AVC) isquêmico agudo. MéTODOS: Os dados de 231 casos consecutivos de AVC isquêmico agudo foram coletados retrospectivamente. Dois cardiologistas independentes interpretaram os registros eletrocardiográficos para PWPT, PWD e amplitude da onda P na derivação DI. O período médio do estudo de acompanhamento foi de 16 (intervalo interquartil [IQR, na sigla em inglês]: 1124) meses. RESULTADOS: No total, FA foi detectada em 43 (18,6%) casos. Todos os parâmetros da onda P estudados foram considerados estatisticamente significativos nos casos com FA. Com base na análise de regressão logística multivariável, demência, índice de volume do átrio esquerdo, PWD (razão de chances [RC]: 1,112; intervalo de confiança [IC] 95%: 1,0581,184; p = 0,003), PWPT na derivação DII (RC: 1,030; IC95%: 1,0101,050; p = 0,003) e avançada morfologia do bloqueio interatrial foram preditores independentes de FA de longo prazo. A PWD teve a maior área sob o valor da curva, sensibilidade e especificidade para FA de longo prazo em tais casos em comparação com os outros parâmetros da onda P. CONCLUSõES: Nossa comparação direta de parâmetros da onda P bem conhecidos demonstrou que a PWD pode ser o parâmetro da onda P mais útil para FA de longa duração em casos de AVC isquêmico agudo.

BACKGROUND: There is a limited data about the one-year outcomes of patients diagnosed with acute coronary syndrome (ACS) and coronavirus disease 2019 (COVID-19). OBJECTIVES: To assess one-year mortality of invasively managed patients with ACS and COVID-19 compared to ACS patients without COVID-19. METHODS: In our investigation, we defined the study time period as April 30 through September 1, 2020. The control groups consisted of ACS patients without COVID-19 at the same time period and ACS patients prior to the pandemic, within the same months as those of the study. COVID-19 infection was confirmed in all participants utilizing real-time polymerase chain reaction testing. RESULTS: This investigation examined 721 ACS participants in total. Among the participants, 119 patients were diagnosed with ACS and COVID-19, while 149 were diagnosed with ACS and without COVID-19. The other 453 ACS participants were diagnosed before the outbreak of the pandemic, within the same months as those of the study. One-year mortality rates were higher in the ACS participants with COVID-19 than in the ACS participants without COVID-19 and the pre-COVID-19 ACS participants (21.3% vs. 6.5% vs. 6.9%, respectively). An ACS along with COVID-19 was the only independent predictor of one-year mortality (HR=2.902, 95%CI=1.211-6.824, P = 0.018). According to the Kaplan-Meier survival curves, patients with ACS and COVID-19 had a lower chance of survival in the short-term and one-year periods. CONCLUSION: This is believed to be the first study to report that ACS patients with COVID-19 had higher one-year risk of mortality compared to ACS patients without COVID-19.

Whole blood viscosity (WBV) is considered as a reasonable proxy measure of blood flow, and it has been investigated in different cohort settings, including in patients with deep venous thrombosis, arterial thrombosis, acute stent thrombosis, and left ventricular apical thrombus formation following acute coronary syndrome. To determine the association between WBV and the presence of thrombus in the left atrium (LA) or left atrial appendage (LAA) in individuals who had transoesophageal echocardiography (TEE). The clinical data from 262 consecutive patients who had TEE at our facility were included in this retrospective cohort study. WBV was determined at both a high shear rate (HSR) and low shear rate (LSR) using hematocrit and total protein levels. In 22 cases (8.3%), the thrombus was detected. According to multivariable analyses, WBV at HSR and LSR were independently linked with thrombus detection in TEE. In a receiver operating characteristic (ROC) analysis, the area under curve (AUC) values of WBV at HSR and LSR were 0.77 and 0.76, respectively. To predict the presence of thrombus in TEE; the ideal value of WBV at HSR was > 16.6 with 81% sensitivity and 69% specificity and the ideal value of WBV at LSR was > 51.4 with 81% sensitivity and 70% specificity. This was the first study to indicate that significantly higher levels of WBV at both the HSR and LSR were linked to the presence of thrombus in the LA and LAA in cases who underwent TEE.

BACKGROUND: Atrial fibrillation (AF) is the most common preventable cause of stroke. Diagnosis of new AF is frequent after acute ischemic stroke (AIS). We aimed to evaluate the predictive value of the recently developed morphology-voltage-P-wave duration (MVP) ECG risk score for in-hospital and long-term AF diagnosis following AIS. MATERIAL AND METHODS: In this observational investigation, we evaluated the ability of the MVP ECG risk score to predict AF in 266 consecutive patients with AIS. The study population was divided into three groups according to their calculated MVP ECG risk score on admission electrocardiography. The groups were compared in terms of their predictive value for in-hospital and long-term AF diagnosis. RESULTS: After adjustment for confounding baseline variables, MVP ECG risk score 5-6 group had 13.2 times higher rates of in-hospital AF compared to MVP ECG risk score 0-2 group, which was used as the reference group. For long-term follow-up, MVP ECG risk score 5-6 group had 5.2 times higher rates of long-term AF compared to MVP ECG risk score 0-2 group. A ROC analysis showed that the optimal cut-off value of the MVP ECG risk score to predict in-hospital AF was 4 with 78% sensitivity and 76% specificity (AUC: 0.80; 95% CI: 0.64-0.96; p < 0.001), the optimal cut-off value of the MVP ECG risk score to predict long-term AF was 3 with 85% sensitivity and 59% specificity (AUC: 0.81; 95% CI: 0.76-0.86; p < 0.001). CONCLUSION: The MVP ECG risk score, which can be easily calculated from a surface ECG, can be used to guide who needs stricter monitoring for the diagnosis of long-term AF in patients with AIS.

OBJECTIVE: The prognostic effect of the mean serum D-dimer levels, which was calculated from the first five days of hospitalization of the patients, has not been elucidated. This study aimed to evaluate the effect of mean D-dimer level about in-hospital mortality in patients hospitalized due to coronavirus disease-2019 (COVID-19) infection. METHODS: In this observational retrospective study, we examined the in-hospital prognostic value of mean D-dimer [D-dimerfirst day+D-dimerthird day+D-dimerfifth day)/3 on 240 consecutive adult patients with COVID-19. Patients were stratified into tertiles according to their mean D-dimer starting from the lowest one. In-hospital mortality rates were compared between tertiles and the power of the mean D-dimer level was also presented by a receiver operating curve analysis. RESULTS: After adjustment for confounding baseline variables, mean D-dimer in tertile 3 was associated with 4.2-fold hazard ratio of in-hospital mortality (odds ratio [OR] 4.2; 95% confidence interval [CI] 1.8-20.1, p<0.001). A receiver-operating curve analysis revealed that the optimal cutoff value of the mean D-dimer to predict in-hospital mortality was 779 µg/L with 77% sensitivity and 83% specificity (area under the curve [AUC] 0.87; 95%CI 0.81-0.94; p<0.001). CONCLUSION: Patients with a higher mean D-dimer level should be followed-up more closely as they may be a candidate for a more aggressive treatment modality, such as biologic agents or convalescent plasma.

Introduction: The objective of the present research was to evaluate the possible association between the N-terminal pro-brain type natriuretic peptide (NT-proBNP) levels and in-hospital mortality in coronavirus disease 2019 (COVID-19) pneumonia patients who did not have pre-existing heart failure (HF). Methods: A total of 137 consecutive patients without pre-existing HF and hospitalized due to COVID-19 pneumonia were enrolled into the current research. The main outcome of the research was the in-hospital death. The independent parameters linked with the in-hospital death were determined by multivariable analysis. Results: A total of 26 deaths with an in-hospital mortality rate of 18.9% was noted. Those who died were older with an increased frequency of co-morbidities such as hypertension, chronic kidney disease, coronary artery disease, stroke and dementia. They had also increased white blood cell (WBC) counts and had elevated glucose, creatinine, troponin I, and NT-pro-BNP levels but had decreased levels of hemoglobin. By multivariable analysis; age, NT-pro-BNP, WBC, troponin I, and creatinine levels were independently linked with the in-hospital mortality. After ROC evaluation, the ideal value of the NT-pro-BNP to predict the in-hospital mortality was found as 260 ng/L reflecting a sensitivity of 82% and a specificity of 93% (AUC:0.86; 95%CI:0.76-0.97). Conclusion: The current research clearly shows that the NT-proBNP levels are independently linked with the in-hospital mortality rates in subjects with COVID-19 pneumonia and without HF. Thus, we believe that this biomarker can be used as a valuable prognostic parameter in such cases.
ABSTRACT
OBJECTIVE: The present study aimed to compare the value of D-dimer measured on the 3rd day of hospitalization with admission D-dimer level in predicting in-hospital mortality in coronavirus disease 2019 (COVID-19) cases. METHOD: In total, 231 patients with COVID-19 disease were included in the study. D-dimer levels were estimated using immunoturbidimetric assay with normal range of 0-500 µg/mL. In the current research, the primary outcome was the in-hospital mortality. RESULTS: In the present research, 39 (16.8%) COVID-19 cases died during the index hospitalization. In a multivariable analysis; age, D-dimer (3rd day) (OR: 1.00, 95% CI: 1.00-1.00, p<0.001), WBC count, and creatinine were independent predictors of the in-hospital death for COVID-19 cases. The ideal value of D-dimer level on the 3rd day of hospitalization was 774 µq/mL (area under curve (AUC): 0.903, 95% CI: 0.836-0.968; p<0.01) with sensitivity of 83.2% and specificity of 83.6%. It was noted that D-dimer level on the 3rd day of hospitalization had a higher sensitivity (83.2% vs 67.6%, respectively) and AUC value than that of D-dimer level on admission (0.903 vs 0.799, respectively). CONCLUSION: The main finding in this investigation was that D-dimer elevation on the 3rd of hospitalization is more sensitive predictor of in-hospital mortality than D-dimer elevation on admission in COVID-19 patients. Even though further investigations are needed to forecast precise prognosis in patients with COVID-19 disease in terms of D-dimer levels, we believe that D-dimer levels on the 3rd day of hospitalization have an enhanced potential to be used as a prognostic marker in routine clinical practice.

BACKGROUND: In the current literature, there is a growing evidence that supports the significant role of inflammation in the progression of viral pneumonia, including patients with coronavirus disease 2019 (COVID-19). AIM: The present study aimed to investigate the predictive value of C-reactive protein/albumin ratio (CAR) for in-hospital mortality in patients with COVID-19. MATERIAL AND METHODS: This retrospective study included the data of 275 consecutive COVID-19 patients who were hospitalized in a referral pandemic center. The CAR ratio was obtained by dividing the CRP level with albumin level. The study population was divided into tertiles (T1, T2, and T3) according to their admission CAR values. The endpoint of the study was a composite outcome of in-hospital mortality. RESULTS: During the in-hospital course, 33 (12%) patients died. The patients classified into T3 group had significantly higher CAR compared those classified into T2 and T1 groups. After the adjustment for the confounders, T3 group had 8.2 (95% CI: 4.2-48.1) times higher rates of in-hospital mortality compared to T1 group (the reference group) in a logistic regression model using CAR values. CONCLUSION: To the best of our knowledge, this is the first study to demonstrate the predictive value of CAR for in-hospital mortality in COVID-19 patients.

BACKGROUND: This study examined the possible association between the prognostic nutritional index (PNI) and in-hospital mortality rates in cases with a high cardiovascular risk burden and hospitalized with the diagnosis of coronavirus disease 2019 (COVID-19). MATERIAL AND METHODS: This retrospective and cross-sectional study included 294 COVID-19 patients hospitalized in a tertiary referral pandemic center. The study cohort was grouped into tertiles based on the initial PNI values as T1, T2, and T3. The PNI was calculated for each case and the prognostic value of this index was compared to CURB-65 and 4C mortality risk scores in predicting in-hospital mortality. RESULTS: Patients stratified into the T1 tertile had a lower lymphocyte count, serum albumin level, and PNI values. In a multivariate analysis, the PNI (OR: 0.688,%95CI: 0.586-0.808, p < 0.001) was an independent predictor for all-cause in-hospital death. After adjusting for confounding independent parameters, patients included in the T1 tertile were found to have 11.2 times higher rates of in-hospital mortality compared to the T3 group, which was presumed as the reference group. In addition, we found that the area under curve (AUC) value of PNI was significantly elevated than that of serum albumin level and total lymphocyte counts alone. [(AUC):0.79 vs AUC:0.75 vs AUC:0.69; respectively). CONCLUSION: This study demonstrated that the PNI is independently related with in-hospital mortality in patient with COVID-19 and cardiovascular risk factors. The power of the PNI was also validated using well-accepted risk scores of COVID-19 such as CURB-65 and 4C mortality risk scores.
