RESUMO

BACKGROUND AND AIMS: Effective treatment of high low-density lipoprotein cholesterol (LDL-C) levels has been shown to improve cardiovascular outcomes of patients with diabetes mellitus (DM). Herein, we aimed to provide insight to the real-life management of patients with DM in terms of LDL-C goal attainment and adherence to lipid management recommendations. Our objective was also to reveal the reasons of poor LDL-C goal attainment by assessing the perceptions of both physicians and patients. METHODS: We compared the diabetic and non-diabetic patients from the database of a nation-wide registry conducted in cardiology outpatient clinics with regard to the demographic characteristics, educational status, comorbidities, medications, laboratory parameters, and LDL-C goal attainment. Also, both the patients and attending physicians were surveyed to analyze perceptions and awareness of hypercholesterolemia. RESULTS: Of the 1868 consecutively enrolled patients, 873 (47%) had DM. Proportion of patients on statins was significantly lower in patients with DM (67.8% vs 55.3%; p<0.001). The proportion of patients who attained LDL-C targets were lower among the diabetic patients (17.8% vs 15%; p=0.06). The most common causes of the discontinuation of statin therapy were negative media coverage about statins (32.1%), and recommendations of physicians to stop the lipid lowering therapy (29.6%). Analysis of the physician survey revealed that the physicians could determine the off-target patients accurately (negative predictive value 98.4%) while the positive predictive value (48.8%) was low. The reasons for not attaining the LDL-C goals in diabetic patients were not prescription of statins (38%) and inadequate (e.g., low-dose, non-adherent) statin (28.3%) dosages. CONCLUSIONS: In real-life clinical cardiology practice, diabetic patients are far below the recommended LDL-C treatment goals. High intensity statin treatment in diabetic population is still avoided because of the concerns about polypharmacy and drug interactions. Also, the inertia of physicians and even cardiologists is probably a major cause of refraining of prescription of optimal statin dosages.

RESUMO

BACKGROUND AND AIMS: Mobile technology-based solutions present promising effects against cardiovascular diseases. Long-term follow-up in mobile phone-based interventions has not yet been elucidated as a primary prevention technique for cardiovascular diseases. The objective of the present trial is to evaluate the effectiveness of lifestyle intervention on the change in the atherosclerotic cardiovascular disease (ASCVD) risk score in a 1-year follow-up using smart phone technology in patients with high cardiovascular risk. METHODS: This prospective, randomised, single-centre clinical investigation enrolled 242 and 241 patients to the intervention plus usual care and usual care arms, respectively. The primary outcome of this study was the 1-year ASCVD risk score adjusted to baseline ASCVD risk score. ASCVD risk scores were calculated for every study participant at the randomisation and final stages. RESULTS: After a 1-year follow-up, the intervention plus usual care reduced the ASCVD score by 2.7% (adjusted treatment effect -2.7, 95% confidence interval (CI): -2.2,-3.3, p<0.0001). An improvement was observed in favour of the intervention plus usual care arm in the majority of the pre-specified secondary endpoints. The high sensitive troponin and high sensitive C-reactive protein levels at 1 year were similar between the two arms. The treatment effect was homogenous for diabetes mellitus, gender, systolic blood pressure, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides and body mass index; however, heterogeneity in the treatment effect was observed for age. CONCLUSIONS: The lifestyle intervention using smart phone technology compared to usual care alone in patients with high cardiovascular risk reduced the ASCVD score at 1-year follow-up.

RESUMO

BACKGROUND: The benefit of implantable cardiac defibrillator (ICD) in patients with heart failure and reduced ejection fraction (HFrEF) could be limited in a particular group of patients. Low prognostic nutritional index (PNI) indicates malnutrition and proinflammatory condition. We sought to investigate the value of PNI in predicting long-term mortality among HFrEF patients with ICD. METHODS: Electronic database was searched for identifying patients with HFrEF who were implanted ICD in our institution between 2009 and 2019. Demographic and clinical characteristics of included patients were recorded. PNI was calculated according to the formula: 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (per mm3 ). Patients were divided into the quartiles according to PNI values. Differences between the groups were analyzed by the log-rank test. A forward Cox proportional regression model was used for multivariable analysis. RESULTS: One thousand and hundred patients were included to the study. The underlying heart failure etiology was ischemic and nonischemic in 77.3% and 22.7% of patients, respectively. Mortality rate in Q1 (5.1%) was considered as the reference. In the unadjusted model the mortality rate was 9.5% (hazard ratio [HR] 1.76, 95% confidence interval [95% CI] [0.92-3.38]) in Q2, 10.2% (HR 1.88, 95% CI 0.99-3.58) in Q3, and 39.6% (HR 8.12, 95% CI 4.65-14.17) in Q4. The same trend was consistent in the age- and sex-adjusted, comorbidities-adjusted, and covariates-adjusted models. CONCLUSION: Among patients who were implanted with ICD secondary to HFrEF, lower PNI value predicted all-cause mortality during long-term follow-up. This is the first study demonstrating the value of PNI in this population.

RESUMO

OBJECTIVES: Pulmonary hypertension (PHT) is one of the essential predictors of mortality in chronic obstructive pulmonary disease (COPD). It is thought that PHT is due to vasoconstriction secondary to hypoxia caused by airway obstruction in COPD patients; however, loss of capillary bed with emphysema, inflammation and endothelial dysfunction may also play a role in the development of PHT. Epicardial adipose tissue (EAT) has a role as a metabolically active endocrine organ and secretes various proinflammatory cytokines. We hypothesized that EAT thickness in COPD patients might be associated with the systolic pulmonary arterial pressure (PAPs) level, and we aimed to test it. METHODS: The present study included 129 consecutive patients with the diagnosis of COPD. All patients underwent transthoracic echocardiographic evaluation. The relationship between PAPs and EAT thickness was evaluated. RESULTS: Positive correlations with PAPs were reported with age, EAT, white blood cell (WBC) and GOLD grade score (range 0.197-0.275, p values 0.026 to 0.002), negative correlations with body-mass index (BMI), hyperlipidemia, FEV1 (% predicted) and pO2 (range -0.216 to -0.340, p values 0.014 to <0.001). In stepwise linear regression analysis, BMI (p=0.003), EAT (p=0.002), WBC (p=0.001), and FEV1 (% predicted) (p=0.010), were independently associated with PAPs. CONCLUSION: EAT thickness in COPD patients with preserved left venticular systolic function is associated with increased PAPs, and this association is independent of the parameters indicating the severity of COPD.

RESUMO

Background: Long-term mortality rate following coronary artery bypass grafting (CABG) procedure is still considered to be high despite advances in surgical techniques and perioperative management. Identifying high-risk patients by using cost-effective and clinically useful parameters is needed. Methods: Patients who were admitted to our cardiology clinic with the diagnosis of coronary artery disease and underwent CABG between January 2008 and August 2010 were included. Study patients were followed-up for 112.6 ± 17.8 months for major adverse cardiac events (MACE) which were defined as all-cause mortality and new-onset decompensated heart failure (HF). Results: Patients in MACE (+) group were older (p < 0.001), had higher additive Euroscore (p < 0.001), and lower left ventricular ejection fraction (p < 0.001). Multivariate Cox regression analysis showed that additive Euroscore [odds ratio (OR) = 1.601; 95% confidence interval (CI) = 1.374-1.864; p < 0.001)] and blood urea nitrogen-to-left ventricular ejection fraction ratio (BUNEFr; OR = 1.028; 95% CI = 1.006-1.050; p = 0.011) independently predicted MACE. Receiver operating characteristic curve analysis demonstrated that BUNEFr had an area under curve of 0.794 and BUNEFr >33 had a sensitivity and specificity of 74% and 64%, respectively. Conclusion: BUNEFr is a clinically useful and cost-effective parameter for the prediction of long-term mortality and new-onset decompensated HF in patients undergoing CABG.

RESUMO

Introduction: It is important to identify those at higher risk for ventricular arrhythmia among hypertensive patients. Epicardial adipose tissue (EAT) leads to electromechanical changes in the heart by endocrine and paracrine effects with cytokines and mediators. Higher amount of EAT carries the risk of QT prolongation. Therefore, we investigated the association between EAT thickness and QTc interval in patients with arterial hypertension. Methods: A total of 230 patients who previously diagnosed with arterial hypertension between February 2019 to March 2020 were included in the study. Patients with atrial fibrillation, U-wave, atrioventricular block, left anterior or posterior fascicular block, right bundle branch block, left bundle branch block, and taking QT-prolonging medication were excluded. The corrected QT (QTc) interval was calculated with Bazzet's formula following the calculated QT interval in the semi-automatic application tool. EAT was measured at the point on the free wall of the right ventricle using transthoracic echocardiography. Results: The mean age was 62.1 ± 11.4 years and 95 (41.3%) of the patients were male. QTc was over 450 ms were considered as the prolonged interval. Both groups were similar in terms of age (p = .862), gender (p = .265) and other demographic characteristics. Left ventricle mass index (LVMI) (82.5 ± 29.5 vs 91.9 ± 32.6 g/1.7.m2, p = .051) and EAT thickness (5.3 ± 2.3 vs 6.6 ± 2.6 mm, p = .001) were higher in the prolonged QTc group. Serum potassium (K) level was lesser in the prolonged QTc group (4.2 ± 0.39 vs 4.1 ± 0.4 mmol/mL, p = .005). Multivariate Cox regression analysis revealed that EAT thickness [OR = 1.227, 95% CI: 1.081-1.393, p = .002] and serum K level [OR = 0.348, 95% CI: 0.157-0.772, p = .009] predicted the prolonged QTc interval, independently. Conclusion: EAT thickness predicted prolonged QTc interval in patients with arterial hypertension. Patients with higher amount of EAT should be followed by closely monitoring to prevent arrhythmic events that may develop in the future. In addition, medications that have a potential effect on QTc interval prolongation may be carefully used in patients with higher EAT thickness.

RESUMO

The clinical presentation of coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2, can range from only mild, flu-like symptoms to severe progressive pneumonia. Cardiac involvement may be observed during the course of the infection and may include myocarditis, acute myocardial infarction, heart failure, and cardiac rhythm disturbances, but cases describing cardiac tamponade in patients previously diagnosed with COVID-19 are very rare. A 58-year-old female had been hospitalized in another hospital 2 weeks prior to the currently described presentation due to atypical pneumonia. A nasopharyngeal swab specimen was positive for COVID-19. The hospitalization was uncomplicated and she was discharged after a week. She presented at our emergency department with symptoms of shortness of breath and swelling in both legs. A bedside transthoracic echocardiography showed globally depressed left ventricular contraction with an ejection fraction of 30% and there was significant pericardial effusion, which surrounded the entire heart and restricted diastolic filling. The patient was admitted to the coronary intensive care unit with the diagnosis of pericardial tamponade. Bedside pericardiocentesis was performed and serohemorrhagic fluid was drained. Pericardial effusion and pericardial tamponade should be considered in the differential diagnosis of patients with COVID-19 exhibiting dyspnea or worsening of dyspnea. A 58-year-old female has been hospitalized in another hospital two weeks ago due to atypical pneumonia. Her nasopharyngeal swab specimen was positive for COVID-19. She had an uncomplicated course during the hospitalization and was discharged a week ago. She presented to our emergency department (ED) with symptoms of shortness of breath and swelling in both legs. We performed bedside transthoracic echocardiography (TTE) which showed globally depressed left ventricular contraction with ejection fraction (EF) of 30% and there was significant pericardial effusion which surrounded the entire heart and restricted diastolic filling. The patient was admitted to the coronary intensive care unit (CICU) with the diagnosis of pericardial tamponade. Bedside pericardiosentesis was performed and serohemorrhagic fluid was drained. Patients with COVID-19 infection who develops or have worsening dyspnea, pericardial effusion and pericardial tamponade should be considered in differential diagnosis.

RESUMO

OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic caused by the emergence of severe acute respiratory syndrome coronavirus 2 has resulted in a health crisis and a significant number of deaths worldwide. The full effect on access to medical care and the treatment for patients with chronic diseases and acute conditions is still unknown. This is an investigation of access to primary percutaneous coronary intervention (PPCI) for patients diagnosed with ST-segment myocardial infarction (STEMI) during the pandemic. METHODS: Consecutive patients who were diagnosed with STEMI and underwent PPCI during the ongoing COVID-19 pandemic were included in the study. Clinical and angiographic characteristics of the patients were assessed. A control group of patients diagnosed with STEMI and who underwent PPCI during the same time interval a year prior to the outbreak of the disease was analyzed retrospectively for comparison. RESULTS: There was a significant reduction in the number of STEMI cases during the COVID-19 crisis period. Furthermore, these patients had a prolonged ischemic time; they were more likely to have a longer pain-to-balloon (Odds ratio [OR]: 2.0, 95% confidence interval [CI]: 1.1-10.2) and door-to-balloon time (OR: 5.4, 95% CI: 3.1-22.8). CONCLUSION: Patients diagnosed with STEMI during the pandemic experienced a significant delay between the onset of symptoms and PPCI.

RESUMO

OBJECTIVE: The Google search engine is widely used as a source of medical information; however, legal and medical governance of the accuracy of the content retrieved is lacking. The aim of this study was to assess the most read Turkish-language texts related to cholesterol during a specific period according to the validity of the content. METHODS: Google Trends was queried on January 5, 2019 for the search term 'cholesterol' and the 9 other most popular search phrases used in Turkey that included the word cholesterol. In all, 100 links were obtained for each phrase, generating a total of 1000 links. Once duplicates were eliminated, a total of 604 links was used for the study. Since there is currently no validation scoring system for this purpose in the literature, the authors created a checklist according to well-accepted recent guidelines focused on cholesterol. The content of the texts acquired was classified as misleading, insufficient but favorable, or sufficient and favorable. RESULTS: The source of the online texts studied was universities (n=8, 1.3%), hospitals (n=6, 0.9%), personal blogs (n=200, 33.1%), health websites (n=183, 30.2%), and medical journals (n=207, 34.2%). In all, 235 texts (38.9%) were classified as sufficient and favorable and 35 (5.7%) were categorized as misleading. A medical practitioner was named in 378 texts (62.5%). All of the results from universities and hospitals were ranked in the favorable group. A statistical difference in the word count was seen in a comparison of the misleading and favorable texts. CONCLUSION: Google can connect users to a significant quantity of material related to cholesterol that includes a wide range from misleading information to sufficient and favorable texts. The variation in the quality of the content on websites accessible via Google necessitates that cholesterol resource material should be selected with great care.

RESUMO

In December 2019, reports of an unknown pneumonia not responsive to traditional treatments arose in Wuhan, China. The pathogen was subsequently identified as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), known to be responsible for the coronavirus disease-2019 (COVID-19) illness, and public health emergency of international concern was declared by the World Health Organization. There is increasing awareness of the cardiovascular manifestations of COVID-19 disease, and the adverse impact of cardiovascular involvement on its prognosis. In this setting, the electrocardiogram (ECG) is one of the leading tools to assess the extent of cardiac involvement in COVID-19 patients, due to its wide disponibility, low cost, and the possibility of remote evaluation. In this article, we review the role of the ECG in the identification of cardiac involvement in COVID-19, highlighting relevant clinical implications.

RESUMO

Asymptomatic bradyarrhythmias involving sinus node dysfunction and atrioventicular blocks are frequently noted in clinical practice. Its prevalence is expected to rise as devices that are developed for monitoring cardiac rhythm for longer duration become more widely available. Episodes of bradyarrhythmia that are asymptomatic are considered to have a benign course compared with those that cause symptoms, and do not necessitate further treatment. However, in certain cases, they can be a harbinger of future symptoms or cardiac manifestations of systemic diseases. The evaluation and risk stratification of individuals presenting with asymptomatic bradyarrhythmias is important not only for preventing implantation of unnecessary permanent pacing devices but also for reducing significant morbidity by implementing proper treatment as required. In this article, we will review the current evidence on the pathophysiology, diagnosis, evaluation and management of patients with asymptomatic bradyarrhythmias.

RESUMO

BACKGROUND: It is important to identify patients that are at high risk following primary percutaneous coronary intervention (P-PCI) for the treatment of ST-segment elevation myocardial infarction (STEMI). Left ventricular ejection fraction (LVEF) is the most important parameter obtained from transthoracic echocardiography (TTE) for risk stratification. The authors evaluated the value of pulmonary artery pressure (PAP) and left atrial volume index (LAVI) for the prediction of major adverse cardiovascular events (MACE) in patients with STEMI that underwent P­PCI. METHODS: A total of 92 patients that underwent P­PCI for STEMI were included in the study. All patients underwent TTE examination before discharge. The composite primary outcome of the study was all-cause mortality and new onset heart failure (HF) during an 8-year follow-up period. RESULTS: The mean age of patients was 61.6 ± 12.4 years and 15 were female (16.3%). Major adverse cardiovascular events (MACE) defined as all-cause mortality and new onset HF occurred in 30 (41%) patients during a mean of 6 ± 2.7 years of follow-up. In the backward multivariate Cox regression analysis LVEF (odds ratio [OR] = 0.933, 95% confidence interval [CI]: 0.876-0.994, p = 0.031), LAVI (OR = 1.069, 95%CI: 1.017-1.124, p = 0.009), PAP (OR = 1.137, 95% CI: 1.057-1.223, p = 0.001) and creatinine level (OR = 1.730, 95% CI: 1.350-1.223, p = 0.029) were found to independently predict MACE during long-term follow-up. Receiver operating characteristic (ROC) curve analysis was performed, revealing that sPAP >24.5 mm Hg had a sensitivity and specificity of 72 and 66%, respectively; LAVI >31 ml/m2 had a sensitivity and specificity of 72.2 and 83.3%, respectively. CONCLUSION: In patients that underwent P­PCI for the treatment for STEMI, LVEF, LAVI, PAP and creatinine level independently predicted all-cause mortality and new onset HF during long-term follow-up.

RESUMO

Electrocardiography (ECG) remains an irreplaceable tool in the management of the patients with myocardial infarction, with evaluation of the QRS and ST segment being the present major focus. Several ECG parameters have already been proposed to have prognostic value with regard to both in-hospital and long-term follow-up of patients. In this review, we discuss various ECG parameters other than ST segment changes, particularly with regard to their in-hospital prognostic importance. Our review not only evaluates the prognostic segments and parts of ECG, but also highlights the need for an integrative approach in big data to re-assess the parameters reported to predict in-hospital prognosis. The evolving importance of artificial intelligence in evaluation of ECG, particularly with regard to predicting prognosis, and the potential integration with other patient characteristics to predict prognosis, are discussed.

RESUMO

BACKGROUND: Recent studies demonstrated that epicardial fat tissue (EFT) was associated with prevalent AF and recurrences following the catheter ablation. We evaluated the value of EFT for the prediction of advanced interatrial block (a-IAB) in the surface electrocardiography (ECG) among hypertensive patients. METHODS: Patients with prior diagnosis of hypertension (HT) were included in the study. Surface ECG and transthoracic echocardiography (TTE) were performed to each patient. A-IAB was defined as P-wave duration longer than 120 ms with biphasic morphology in the inferior leads. EFT was identified by using TTE and was measured perpendicularly in front of the right ventricular free wall at the end-systole. RESULTS: Between February 2019 and February 2020 245 patients met the eligibility criteria. A-IAB was found among 35 patients and compared to those without IAB, they had increased waist circumference, elevated left ventricular mass index (LVMI) and left atrial volume index (LAVI), lower LDL and increased P wave duration. EFT thickness was higher in patients with a-IAB compared to those without (5.3 ±â€¯2.2 mm vs 7.6 ±â€¯2.4 mm). Multivariable analysis revealed that increased EFT thickness and lower LDL level predicted a-IAB. CONCLUSION: Among patients with prior diagnosis of HT, higher EFT thickness evaluated by TTE predicted the presence of a-IAB on the surface ECG.

RESUMO

In December 2019, in the city of Wuhan, in the Hubei province of China, treatment-resistant cases of pneumonia emerged and spread rapidly for reasons unknown. A new strain of coronavirus (severe acute respiratory syndrome coronavirus-2 [SARS-CoV-2]) was identified and caused the first pandemic of the 21st century. The virus was officially detected in our country on March 11, 2020, and the number of cases increased rapidly; the virus was isolated in 670 patients within 10 days. The rapid increase in the number of patients has required our physicians to learn to protect both the public and themselves when treating patients with this highly infectious disease. The group most affected by the outbreak and with the highest mortality rate is elderly patients with known cardiovascular disease. Therefore, it is necessary for cardiology specialists to take an active role in combating the epidemic. The aim of this article is to make a brief assessment of current information regarding the management of cardiovascular patients affected by COVID-19 and to provide practical suggestions to cardiology specialists about problems and questions they have frequently encountered.

RESUMO

OBJECTIVES: Previous studies showed that subclinical abnormal left atrial (LA) function could be diagnosed with LA speckle tracking evaluation long before chamber enlargement. Osteoprotegerin (OPG) is a member of the tumor necrosis factor (TNF) receptor superfamily and was recently found to be an indicator for adverse cardiovascular outcomes and a risk factor for new onset atrial fibrillation. The authors hypothesized that OPG values could predict LA mechanical dysfunction and LA remodeling assessed by two-dimensional speckle tracking echocardiography (2D-STE) in patients with hypertension (HT) and diabetes mellitus (DM). METHODS: A single center study was conducted including consecutive patients presenting to the authors' outpatient clinic. Enrolled patients needed to have been treated for HT and DM for at least 1 year. RESULTS: The study included 80 patients (mean age, 57.5 ± 8.3 years). Patients in the impaired LA strain group were older (p = 0.035), had lower low density lipoprotein (LDL) cholesterol (mg/dl) (p = 0.021), and higher OPG (pmol/l) (p = 0.004) values than patients in the normal LA strain group. Univariate logistic regression analysis demonstrated that age (p = 0.039), LDL cholesterol (mg/dl) (p = 0.025), and OPG (pmol/l) (p = 0.008) values were associated with impaired LA strain. Backward multivariate logistic regression analysis showed that LDL cholesterol (mg/dl) (OR: 0.982, CI 95% 0.964-0.999, p = 0.049) and OPG (pmol/l) (OR: 1.438, CI 95% 1.043-1.983, p = 0.027) were independently associated with impaired LA strain. CONCLUSION: In hypertensive and diabetic patients, higher OPG values were associated with impaired LA function assessed by 2D-STE. In this high-risk patient group, serum OPG can be used as a risk predictor for LA mechanical dysfunction.

RESUMO

His bundle pacing (HBP) provides physiological ventricular activation and is frequently used to treat patients with bradyarrhythmias. HBP reduces the risk of developing heart failure and atrial fibrillation by preventing ventricular electromechanical dyssynchrony associated with conventional right ventricular pacing. There are two types of HBP, including selective (S-HBP) and non-selective HBP (NS-HBP). It is important to determine the type of HBP during implantation and follow-up. This review discusses the role of standard surface electrocardiography in differentiating S­HBP and NS-HBP and diagnosing loss of His bundle capture.

RESUMO

BACKGROUND: Erectile dysfunction (ED) has been proposed as an early indicator for future coronary and peripheral vascular disease. AIM: We aimed to investigate the longitudinal change in proportion and predictors for ED with changes in erectile function domain (EFD) of the International Index of Erectile Function-15 (IIEF-15) in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PPCI). METHODS: Between December 2018 and June 2019, 286 male patients aged between 40 and 70 years who were treated with PPCI for STEMI were included. The patients were asked to complete the IIEF-EFD form 3 days after the procedure for the evaluation of baseline erectile functions. During follow-up 3 months after the index procedure, the patients were asked to refill the IIEF-EFD form. Both baseline and third-month IIEF-EFD scores were calculated, and the patients were classified into ED severity groups as per the IIEF-EFD scores. A linear mixed model was used to identify predictors of ED at 3 months. OUTCOMES: This study identifies the prevalence and predictors of ED with STEMI who underwent PPCI. RESULTS: The median age was 54 (range 48-61) years. The median IIEF-EFD scores at 3 days and 3 months were 25.5 (range 20.0-27.0) and 22.00 (range 18.25-25.00), respectively. Half of the patients were found to have ED with varying severity as per baseline IIEF-EFD scores. This rate increased to 79% at the 3-month follow-up visit. The IIEF-EFD scores of the patients decreased over time (P < .001). Advanced age (ß = -0.603, se = 0.192, P = .002), presence of three-vessel coronary artery disease (ß = -3.828, se = 0.783, P < .001), and diabetes (ß = -2.934, se = 0.685, P < .001) were found to be inversely associated with the IIEF-EFD scores. CLINICAL IMPLICATIONS: Advanced age, presence of three-vessel disease, and diabetes mellitus are the indicators of sexual rehabilitation needs in patients after STEMI. STRENGTHS & LIMITATIONS: This is the first study investigating the predictor variables for the development of ED after coronary artery disease treatment. The limitations include the lack of evaluation of anxiety and depression and the measurements of testosterone levels. CONCLUSION: The prevalence of ED was high among patients with coronary artery disease, and the frequency of ED increased during 3-month follow-up. Advanced age, three-vessel disease, and diabetes were significant predictors of ED with changes in IIEF-EFD score in patients with STEMI who underwent PPCI. Karabay E, Karsiyakali N, Cinier G, et al.

RESUMO

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality throughout the world and contributes a considerable burden to healthcare costs. Primary prevention strategies, particularly adopting healthy lifestyle habits, have great potential to reduce the risk of CVD. Patient compliance remains the major cause of the failure of primary prevention strategies. Telehealth interventions and gamification through mobile applications can increase adherence and reduce healthcare costs. The primary objective of this study is to compare the effect of lifestyle intervention using mobile technology plus usual care with usual care alone in patients with a high CVD risk.
