The Impact of Education on Patients Eligible for Cardiac Rehabilitation and Factors Contributing to Declining Participation in Turkish Society: Are Patients Aware of Cardiac Rehabilitation?

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.

Evaluation of high altitude training camps with heart rate recovery and heart rate variability analysis: beneficial effect in elite swimmers.

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.

The Effect of Night Shift on Blood Pressure in Healthcare Workers.

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.

Aortic Origin Coronary Artery Anomalies: A Case Series.

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.

Evaluation of the non-alcoholic fatty liver fibrosis score in predicting short-term outcomes and severe coronary artery disease in patients undergoing coronary computed tomography angiography.

Introduction: The correlation between non-alcoholic fatty liver disease (NAFLD) and cardiovascular disease is well established. Aim: The objective of this study was to assess the short-term associations of the non-alcoholic fatty liver disease fibrosis score (NFS) with various outcomes, including mortality, severe coronary artery disease, myocardial infarction, and the need for coronary angiography, among patients who underwent coronary computed tomographic angiography (CCTA). Material and methods: In this study, we assessed 499 patients who underwent 640-slice CCTA and evaluated their liver fibrosis using the NFS. The NFS takes into account factors such as age, body mass index, impaired fasting glycemia or diabetes mellitus, aspartate aminotransferase/alanine aminotransferase ratio, platelets, and albumin. Our primary focus was myocardial infarction, the need for coronary angiography, and death. Additionally, we examined the association between NFS and severe coronary artery disease. Results: Patients with a higher NFS had a greater number of coronary angiography procedures and higher Agatston score (p < 0.001), with NFS and Agatston score emerging as independent predictors of severe coronary artery disease and the primary endpoint. An NFS value above -0.92 could predict the primary endpoint with 61% sensitivity and 63% specificity, while an NFS value above -0.88 could predict severe coronary artery disease with 62% sensitivity and 65% specificity. To analyze primary endpoints, the Kaplan-Meier method was used for survival analysis, with NFS groups compared using the log-rank test. During the follow-up period, patients with higher NFS were exposed to primary outcomes at an earlier period (p = 0.009). Conclusions: NFS is an effective predictor of major cardiovascular events such as death, myocardial infarction, severe coronary artery disease, and the need for coronary angiography. These findings underscore the importance of NFS as a valuable tool for risk assessment and early intervention in patients with suspected or confirmed coronary artery disease.

Role of Resistance Exercise in Cardiology.

Resistance exercise is a form of exercise that increases muscular strength and endurance by exercising a muscle or muscle group against external resistance. Resistance exercises have an important potential in preventing cardiac diseases, increasing treatment efficiency, and improving quality of life. In spite of the fact that the vast majority of cardiology research to date has focused on aerobic exercise, an increasing number of studies on resistance exercise have been published in the past few years. Although resistance exercise was combined with aerobic exercise in most of these studies, its isolated efficacy was also examined. In conditions such as coronary artery disease, peripheral artery disease, heart failure, arrhythmias, and cardiac rehabilitation, resistance exercise (RE) is regarded as a potentially beneficial approach. In addition to interventional and medical treatments, resistance exercise can also be considered as a cost-effective and sustainable method. The effects of resistance exercise on a variety of cardiovascular conditions were investigated in this evaluation of the literature.

Interventional Treatment Options for the Prevention of Amputation in Patients With Lower Extremity Wounds From Peripheral Arterial Disease.

BACKGROUND: Peripheral arterial disease and related lower extremity wounds are prominent causes of amputation. Revascularization may reduce amputation rates or the amputation margin more distally in patients with peripheral arterial disease who have wounds resulting from critical limb ischemia. This study examined the association of risk factors and intervention types with amputation rates in patients with critical lower extremity arterial disease. METHODS: A total of 211 patients who underwent peripheral intervention because of foot wound were followed up for 12 months after the intervention. All patients had lower extremity wounds resulting from peripheral arterial disease. The effects of treatment approaches were compared in patients who underwent and did not undergo amputation. RESULTS: Revascularization of the anterior tibial artery reduced the amputation rate by 6.52 times compared with occlusion. Posterior tibial artery revascularization reduced the amputation rate by 49.95 times. CONCLUSION: In this study of percutaneous intervention methods for prevention of amputation, the most effective option was revascularization of the posterior tibial artery and anterior tibial artery. Considering these results, treatment of critical peripheral arterial disease can be cost-effective and efficient and may shorten procedure time.

Inadvertent misplacement of pacemaker lead presented with acute ischemic stroke.

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.

Comparison of the effects of resistance, aerobic and mixed exercise on athlete's heart.

BACKGROUND: There are various changes in cardiac physiology in athletes compared to the normal population. These physiological changes may differ according to the exercise content. The aim of this study was to compare the effects of different exercise methods on the heart. METHODS: A total of 122 male athletes from various sports were evaluated. Depending on the sorts of sports, these participants were split into aerobic, mixed, and resistance groups. Each athlete had to meet the inclusion criteria of having participated in the present sport for at least a year and having trained for at least 600 minutes per week over the previous three months. Transthoracic echocardiography was used to investigate the effects of different exercise types. RESULTS: The aerobic group's heart rate and ejection fraction were found to be lower than those of the resistance and mixed groups (F(2.105)=23.487, P=0.001). The end-diastolic thicknesses of the interventricular septum (8.7 SD 0.8 vs. 10.0 SD 0.7), interventricular septum (11.3 SD 0.9 vs. 13.0 SD 0.9), left ventricular posterior wall (8.6 SD 0.7 vs. 9.9 SD 0.8), and interventricular septum (11.1 SD 0.9 vs. 13.3 SD 0.9) were all found to be lower in the aerobic group than in the resistance group (P=0.0001). The effect of resistance exercise on heart rate was not observed as clearly as other groups. CONCLUSIONS: Resistance exercise has a more dominant effect on ventricular thickness than aerobic exercise. In mixed exercise groups, this increase in thickness is similar to resistance exercise. The content of the training should be considered in the evaluation of the athlete's heart. Identifying the subgroups of the athlete's heart will be useful in the differentiation of pathologies and also in the follow-up of the athletes.

Acute Myocardial Infarction Due to Myocardial Bridge Treated With Surgery: a Case Report.

Myocardial bridging is congenital anomaly characterized by segment of epicardial coronary arteries passing through the myocardium. Various ischemic conditions are related with this pathology. We report a case of myocardial bridging that was complicated with acute anterior myocardial infarction and a review of the literature. The patient was treated successfully with coronary bypass graft surgery after unsuccessful percutaneous intervention.

Misplacement of pacemaker leads: How to avoid and how to approach?

The use of cardiac implantable electronic devices has increased in recent years due to factors such as a growing population, increased life expectancy, and improved access to healthcare services. In parallel with this trend, complications related to pacemakers have also increased. One of the most important and preventable complications among these is lead misplacement. Misplacement of a permanent pacemaker lead in the LV can lead to a variety of complications, including damage to the heart muscle, arrhythmias, blood clotes and cerebrovascular events. It is recommended to use the fluoroscopic 40° LAO view during implantation. That view clearly defines the interatrial and interventricular septum. Right bundle branch block pattern on ECG is an important clue to suspected misplaced lead. In addition to the postero-anterior (PA) projection of x-ray, the latero-lateral (LL) projection provides a clearer view of lead malposition. In the LL view, the tip of an incorrectly positioned LV lead is characteristically directed toward the spine. If diagnosed soon after implantation, percutaneous lead extraction can reduce the risk of future thromboembolic events without the need for lifelong anticoagulation. It should be noted that in cases with a lead in the LV for a long time, lead removal is not the primary recommendation. Patient-based approach should be fundamental.

A Rare Case of Aggressive Infective Endocarditis Due to Corynebacterium striatum.

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.

Prognostic Value of Systemic Immune-Inflammation Index in Predicting Premature Saphenous Vein Graft Disease in Patients With Coronary Artery Bypass Grafting.

BACKGROUND: Systemic inflammation is a risk factor for premature coronary artery disease (CAD), and systemic immune-inflammation index (SII), a new marker of systemic inflammation, is linked to the severity and prognosis of CAD. However, the prognosis of the SII in bypass patients' venous saphenous grafts has not been adequately evaluated. This study aimed to evaluate the prognostic value of SII in predicting premature saphenous vein graft disease (SVGD) in patients who underwent bypass surgery with venous saphenous grafts. METHODS: We retrospectively included 422 patients who had saphenous vein grafts (SVG) at least one year after bypass surgery. Of these, 222 patients had SVGD, and 200 had patent SVG. RESULTS: SII was higher in the SVGD group than in the control group (631.55 ± 397.84, 421.71 ± 351.07, P=0.001). A receiver operating characteristic (ROC) analysis was performed to identify the optimal cutoff point with the highest sensitivity and specificity. The optimal cutoff point for SII was defined as 430. Using a cutoff level of >430, SII predicted SVGD with a sensitivity of 73% and specificity of 56%. CONCLUSION: Our study demonstrated that SII was substantially higher in patients with SVGD than in those with patent SVG. SII predicted SVGD in bypass surgery patients. SII may be a helpful parameter for identifying patients at high risk of SVGD and guiding preventive treatments.

Long-Term Observational Study of the Isolated Ostial Diagonal Stenosis in Patients with Chronic Coronary Syndrome.

OBJECTIVE: Isolated ostial diagonal stenoses are very rare lesions in which percutaneous intervention could cause significant vessel compromise, and the long-term results have been reported in a few studies. This study sought the characteristics and long-term follow-up of the patients with isolated osteal diagonal stenosis regarding percutaneous coronary intervention and presence of angina. METHODS: The study was an observational retrospective study conducted between January 2014 and December 2020. A total of 9769 patients who underwent coronary angiography were analyzed, and 87 patients had isolated diagonal stenosis. The patients were evaluated according to treatment modality and angina severity in long-term pattern. RESULTS: Median follow-up time was 36 months. A total of 54 (83.1%) patients were followed up with only medical treatment, and 11 (16.9%) patients underwent revascularization in addition to medical treatment. The degree of stenosis of the diagonal artery was significantly higher in the percutaneous coronary intervention group than medical group (P = 0.002) and the patients with wider reference diameter of diagonal artery complaint of more angina (P = 0.007). Class I angina was significantly higher in percutaneous coronary intervention group than medical and the patients with no angina were significantly higher in medical group than percutaneous coronary intervention group. CONCLUSION: Percutaneous coronary intervention was mainly performed for diagonal arteries with a higher degree of stenosis; however, the patients who underwent percutaneous coronary intervention had angina more than 50% rates. Furthermore, the patients with ongoing angina had a larger diameter of the diagonal artery regardless of the type of treatment.

Radiographic predictors of failure of simple manual traction of transvenous implantable cardioverter-defibrillator leads: a single-center experience.

BACKGROUND: Extraction of the implantable cardioverter-defibrillator (ICD) leads could be a difficult procedure due to fibrous tissue around the lead and anatomical variations. In this report, we present our experience in the radiographic predictors of failure of simple manual traction (SMT) in patients with dual-coil ICD requiring lead extraction (LE). METHODS: Between January 2017 and February 2021, 103 leads were removed in 65 consecutive patients; 65 (63.1%) were dual-coil ICD leads, 22 (21.4%) were atrial, and 16 (15.5%) were coronary sinus leads. Patient-based and procedural data were collected and analyzed retrospectively. Clinical and procedural characteristics were compared and radiographic predictors of failure of SMT of ICD leads were assessed. Projected anteroposterior (AP) lead tortuosity was measured and lead slack score was estimated on chest X-ray (CXR). RESULTS: Simple manual traction failed in 27 (42%) of the ICD leads. Ottawa slack score (odds ratio [OR] 2.368, 95% CI [1.261-4.447]; P = 0.007), AP lead tortuosity > 1.10 (OR 7.477, 95% CI [1.718-35.542]; P = 0.007), and number of previous interventions (OR 6.016, 95% CI [1.184-30.557]; P < 0.030) were found to be independently related to the failure of SMT. Receiver-operator characteristic curve analysis yielded an AP lead tortuosity cutoff value of > 1.10 for predicting the failure of SMT. The area under the curve was 0.744; the 95% confidence interval (CI) was 0.617 to 0.871 (P = 0.001), with a sensitivity of 63% and a specificity of 73%. CONCLUSION: Simple manual traction success in our study varied based on radiographic lead-related parameters. Before planning the procedure, increased AP lead tortuosity in vasculature and higher lead slack score can be easily determined on CXR and may be associated with more fibrous adherences, the complexity of the LE, and failure of SMT.
