Sleep Quality and Its Predictors among Dyspnea, Fatigue and Exercise Capacity in Pulmonary Arterial Hypertension.

Background: Poor sleep quality is an overlooked symptom in patients with pulmonary arterial hypertension (PAH), however it may significantly contribute to disease burden. Objectives: The aim of this study was to assess the sleep quality of patients with PAH and investigate its association with dyspnea, fatigue, and exercise capacity. Methods: Forty-five patients were included. Sleep quality of the patients was assessed by the Pittsburgh Sleep Quality Index (PSQI), dyspnea levels were assessed by the UCSD-Shortness of Breath Questionnaire (UCSD-SOBQ), Baseline Dyspnea Index (BDI), Modified Medical Research Council (MMRC) dyspnea scale and Modified Borg Dyspnea scale, fatigue levels were evaluated with the Fatigue Severity Scale and Borg Rating of Perceived Exertion, and functional exercise capacity was evaluated with the 6-minute walk test (6MWT). Results: Among the patients with PAH, 64% had poor sleep quality (PSQI > 5). PSQI score was significantly correlated with MMRC scale (r = -0.561), UCSD-SOBQ (r = 0.497), BDI (r = -0.468), and 6MWT (r = -0.412) (p < 0.05). There was no significant relationship between sleep quality and fatigue. A regression model including MMRC and 6MWT could explain 32% of variance in PSQI (p < 0.05), and MMRC score was an independent predictor for PSQI (p < 0.05). In addition, MMRC score had a greater influence on PSQI than 6MWT (ß = 0.548 vs. 0.019). Conclusions: Poor sleep quality is common in patients with PAH and is associated with poor exercise capacity and dyspnea. Patients with severe dyspnea are particularly at higher risk of poor sleep quality. Consideration of sleep-related complaints and underlying mechanisms when planning symptomatic treatments for these patients may help provide better management for PAH.

Real-world data on Empagliflozin and Dapagliflozin use in patients with HEART failure: The RED-HEART study.

AIMS: We aimed to determine the use of sodium-glucose cotransporter 2 inhibitors (SGLT2is) and to identify clinical factors associated with their use in patients with heart failure (HF) in a real-life setting. METHODS: Real-world data on Empagliflozin and Dapagliflozin use in patients with HEART failure: The RED-HEART study is a multicentre, cross-sectional and observational study that included HF patients in the outpatient setting regardless of ejection fraction from 19 cardiology centres between August 2023 and December 2023. RESULTS: The study population consisted of 1923 patients with HF, predominantly men (61.2%), with a median age of 66 (range: 19-101) years. Overall, 925 patients (48.1%) were receiving SGLT2is. Among the study population, 22.1% had HF with preserved ejection fraction, 21.5% had HF with mildly reduced ejection fraction, 56.4% had HF with reduced ejection fraction and the use of SGLT2is was 42.0%, 47.9% and 50.6% in each group, respectively (P = 0.012). The use of SGLT2is was 76.6% in patients with HF and diabetes, 19.8% in patients with HF and chronic kidney disease and 26.8% in patients without diabetes and chronic kidney disease (P < 0.001). Higher education level [odds ratio (OR): 1.80; 95% confidence interval (CI): 1.06-3.05; P = 0.027], higher household income (OR: 3.46; 95% CI: 1.27-9.42; P = 0.015), New York Heart Association functional class IV (OR: 2.72; 95% CI: 1.16-6.35; P = 0.021), diabetes (OR: 9.42; 95% CI: 6.72-13.20; P < 0.001), the use of angiotensin receptor-neprilysin inhibitors (ARNis) (OR: 4.09; 95% CI: 2.39-7.01; P < 0.001), the use of mineralocorticoid receptor antagonists (MRAs) (OR: 2.02; 95% CI: 1.49-2.75; P < 0.001), the use of loop diuretics (OR: 1.62; 95% CI: 1.18-2.22; P = 0.003) and the use of thiazide diuretics (OR: 1.72; 95% CI: 1.30-2.29; P < 0.001) were independently associated with the use of SGLT2is. Conversely, atrial fibrillation (OR: 0.63; 95% CI: 0.45-0.88; P = 0.008), chronic kidney disease (OR: 0.53; 95% CI: 0.37-0.76; P = 0.001), the use of dihydropyridine calcium channel blockers (OR: 0.68; 95% CI: 0.48-0.98; P = 0.042) and the use of statins (OR: 0.67; 95% CI: 0.49-0.91; P = 0.010) were independently associated with the non-use of SGLT2is. CONCLUSIONS: The RED-HEART study provided comprehensive real-world data about implementing SGLT2is in patients with HF. These results suggest that there is a need for organized action and close collaboration between healthcare providers to improve the implementation of SGLT2is, especially in patients with HF with preserved ejection fraction and chronic kidney disease.

Evaluation of preprocedural statin loading on clinical outcomes in patients undergoing elective percutaneous coronary intervention.

Background and aim: High-dose statin therapy before percutaneous coronary intervention (PCI) is thought to reduce the occurrence of Peri-procedural Myocardial Infarction (PPMI), which is associated with increased mortality and prolonged hospitalization, especially in statin naïve patients. This study aims to investigate the effect of rosuvastatin loading dose on PPMI and major adverse cardiac and cerebrovascular events (MACCE) in patients undergoing elective PCI, considering their statin use. Methods: One hundred sixty-five patients with stable coronary artery disease (CAD) without heart failure (HF) or chronic kidney disease (CKD) were included in the study. They were divided into two groups: patients already on statin treatment (n:126) and statin naive patients (n:39). Both groups were randomly assigned to high-dose (40 mg) rosuvastatin (n:86) or a non- loading dose group (n:79). The primary endpoint was the incidence of PPMI, and the secondary endpoint was MACCE. Results: The mean age of study population was 59 ± 9.4 years with 77% being male (n = 127). The median follow-up (FU) time was 368 day. Thirty patients were diagnosed with PPMI after PCI (19 in the high-dose group and 11 in the no-loading-dose group). Meanwhile, less than half of study population (77 patients, 46.7%) had complex lesion type (B2, C) and 88 of those (53.3%) had simple lesion type (A, B1). PPMI was observed more frequently in statin-naive patients (23%) than in statin users (17%), although the difference was not statistically significant. Only two patients (1.2%) experienced MACCE during the FU period. One of these patients, who had a type C lesion, belonged to group A2 and underwent Target Vessel Revascularization (TVR) on the 391st day. The other patient, with a type B1 lesion, was in group A1 and was hospitalized due to Acute Coronary Syndrome (ACS) on the 40th day of FU. Conclusions: Pre-procedural administration of high dose rosuvastatin in patients with stable coronary artery disease did not decrease PPMI, independent of chronic statin use.

Evaluation of potential links between phenotypic features and genetic variants in left ventricular outflow tract obstruction in hypertrophic cardiomyopathy using cardiovascular magnetic resonance imaging.

This study aimed to identify the phenotypic features contributing to the development of left ventricular outflow tract obstruction (LVOTO) in patients with hypertrophic cardiomyopathy (HCM) and to evaluate the genotype‒phenotype relationship. This cross-sectional study included 96 patients diagnosed with HCM (mean age: 56.9 ± 13.5 years, 32.3% female). The patients were divided into hypertrophic nonobstructive cardiomyopathy (HNCM; n = 60) and hypertrophic obstructive cardiomyopathy (HOCM; n = 36) groups. All patients underwent CMR. Patients (n = 77) who had previously provided formal approval underwent a genetic examination that included 18 genes. The anterior mitral leaflet (AML) length/LVOT diameter ratio, posterior mitral leaflet (PML) length/LVOT diameter ratio, and anterolateral papillary muscle (AL-PM) mobility were associated with LVOTO, independent of the basal IVS thickness, abnormal chordal attachment, and bifid PM. An AML length/LVOT diameter ratio of ≥ 2.30, a PML length/LVOT diameter ratio of ≥ 1.83, and an AL-PM mobility of ≥ 57.7% were predictors of LVOTO, with good sensitivity and specificity. Positive variants (VUS, LP, and P) were detected in 37.7% (29 of 77) of the patients who underwent genetic testing. The LP/P variant was detected in 20.8% (16 of 77) of patients. Three groups (variant-negative, VUS, and LP/P groups) had significant differences in the LVOT diameter (median 14, 12, and 10 mm, respectively; p = 0.021), AML length (mean 25.3, 26.5, and 27.5 mm, respectively; p = 0.029), AML length/LVOT diameter ratio (median 1.74, 2.33, and 2.85, respectively; p = 0.006), PML length/LVOT diameter ratio (median 1.29, 1.82, and 2.10, respectively; p = 0.045), and abnormal chordal attachment (6.3%, not observed, and 31.3%, respectively; p = 0.009). The AML length/LVOT diameter ratio, PML length/LVOT diameter ratio, and AL-PM mobility were associated with LVOTO. In addition, genetic testing results may provide information regarding the phenotypic expression of patients with HCM.

Evaluation of upper extremity functional capacity and activities of daily living in patients with heart failure: A cross-sectional study.

BACKGROUND: Considering the limitations in activities of daily living (ADL) and the impact of improvements in patients with heart failure (HF), appropriate assessment of upper extremity functional capacity and ADL is important. OBJECTIVES: To evaluate upper extremity functional capacity and ADL in patients with HF and compare them with healthy controls. METHODS: This study included 30 HF patients and healthy controls. Upper extremity functional capacity was assessed with the 6-Minute Pegboard Ring Test (6PBRT), ADL by the Londrina protocol, exercise capacity by 6-Minute Walk Test (6MWT), peripheral muscle strength by hand dynamometer, and dyspnea by Modified Medical Research Council Scale (MMRC). For performance tests, pre-test (resting) and post-test (after performance) values ​​were also measured. RESULTS: Patients with HF with ejection fraction ≤50 % and controls were similar in terms of age (52.63±6.2 and 50.03±6.5 years, respectively) and gender (25 females for each group) (p > 0.05). Patients showed a statistically significant increase in total test time in the Londrina protocol and fewer rings moved in 6PBRT (p < 0.0001). The post-test dyspnea (p = 0.03) and pre-test arm fatigue (p < 0.0001) were observed to be higher in patients in the Londrina protocol. There was a statistically significant group by time interaction in the patients' pre- and post-test lower heart rate (F= 4.80, p = 0.03), post-test dyspnea (p < 0.0001), and post-test arm fatigue (p = 0.005) were observed to be higher in patients in 6PBRT. CONCLUSIONS: The evidence showed a decrease in upper extremity functional capacity in patients with HF. Patients required more time to perform their ADLs compared with healthy controls.

Real-World Data on the Incidence of Stroke, Myocardial Infarction, and Mortality Among Nonvalvular Atrial Fibrillation Patients in Türkiye: New Oral Anticoagulants-TURKey Study.

BACKGROUND: Atrial fibrillation (AF) is strongly associated with an increased risk of ischemic events. Anticoagulation focuses on reducing the risk of embolism. Guideline recommended CHA2DS2-VASc scoring system is most widely used; however, different scoring systems do exist. Thus, we sought to assess the impact of anticoagulant treatment and different scoring systems on the development of stroke, myocardial infarction, and all-cause mortality in patients with nonvalvular AF. METHODS: The present study was designed as a prospective cohort study. The enrollment of the patients was conducted between August 1, 2015, and January 1, 2016. The follow-up period was defined as the time from enrollment to the end of April 1, 2017, which also provided at least 12 months of prospective follow-up for each patient. RESULTS: A total of 1807 patients with AF were enrolled. During the follow-up, 2.7% (48) of patients had stroke, 0.8% (14) had myocardial infarction, and 7.5% (136) died. The anticoagulation and risk factors in AF (ATRIA) score had a better accuracy for the prediction of stroke compared to other scoring systems (0.729, 95% CI, 0.708-0.750, P <.05). Patients under low-dose rivaroxaban treatment had significantly worse survival (logrank P <.001). Age, CHA2DS2-VASc score, R2CHADS2 score, ATRIA score, chronic heart failure, prior stroke, and being under low-dose rivaroxaban treatment were independent predictors of clinical endpoint (P <.001). CONCLUSION: Low-dose rivaroxaban treatment was independently and strongly associated with the combined clinical endpoint. Furthermore, the ATRIA score proved to be a stronger predictor of stroke in the Turkish population.

A Breathtaking Case of Pulmonary Hypertension with Frightening Complications and Intertwining Different Etiologies.

Pulmonary hypertension (PH) is a major health problem with increasing awareness. Although most common cause of PH is left heart disease (Group 2 PH), life-threatening complications occur mostly in Group 1 (pulmonary arterial hypertension) and Group 4 (chronic thromboembolic PH) patients. Although external compression of the left main coronary artery (LMCA) due to pulmonary artery dilatation is rare, it is a life-threatening complication since it causes myocardial ischemia and sudden cardiac death. In addition, PH is more than a single clinical entity due to its complex mechanism in which more than one subgroup may develop over time in the same patient. This complex mechanism challenges us when diagnosing the patient and faces us with life-threatening complications. In this case; we report a pulmonary arterial hypertension patient applied to our clinic with progressive dyspnea and recent angina, after detection of LMCA ostial stenosis, the patient was treated with intravascular ultrasound-guided stent implantation. In the further follow-ups, the patient underwent the pulmonary endarterectomy operation due to the diagnosis of chronic thromboembolic pulmonary hypertension secondary to newly diagnosed primary antiphospholipid syndrome.

Six-Minute Walk Test: How to do Guide for Performing a Reliable Test, Interpretation, and Prognostication in Pulmonary Hypertension.

Six-minute walk test (6MWT) is the most widely used exercise capacity measurement worldwide in patients with pulmonary hypertension (PH). Although cardiopulmonary exercise testing (CPET) is the gold standard for the assessment of exercise capacity in cardiovascular diseases; the limited accessibility of the device, the need for experience in interpreting the results, and the difficulties in performing CPET in advanced PH have aroused the interest in the application of easier methods for the measurement of exercise capacity. Since then, accumulated data proved that; 6-minutes walking distance (6MWD) can be used to determine exercise capacity and is highly correlated with maximum oxygen consumption (peak VO2) detected by CPET in patients with heart failure and/or PH. Moreover, 6MWT is very easy and practical to apply in all PH subgroups. This review is focused on the application of a reliable 6MWT and the interpretation of the results in patients with PH.

Prognostic significance of medical therapy in patients with heart failure with reduced ejection fraction.

AIMS: The use of guideline-directed medical therapy (GDMT) among patients with heart failure (HF) with reduced ejection fraction (HFrEF) remains suboptimal. The SMYRNA study aims to identify the clinical factors for the non-use of GDMT and to determine the prognostic significance of GDMT in patients with HFrEF in a real-life setting. METHODS AND RESULTS: The SMYRNA study is a prospective, multicentre, and observational study that included outpatients with HFrEF. Patients were divided into three groups according to the status of GDMT at the time of enrolment: (i) patients receiving all classes of HF medications including renin-angiotensin system (RAS) inhibitors, beta-blockers, and mineralocorticoid receptor antagonists (MRAs); (ii) patients receiving any two classes of HF medications (RAS inhibitors and beta-blockers, or RAS inhibitors and MRAs, or beta-blockers and MRAs); and (iii) either patients receiving class of HF medications (only one therapy) or patients not receiving any class of HF medications. The primary outcome was a composite of hospitalization for HF or cardiovascular death. The study population consisted of 1062 patients with HFrEF, predominantly men (69.1%), with a median age of 68 (range: 20-96) years. RAS inhibitors, beta-blockers, and MRAs were prescribed in 76.0%, 89.4%, and 55.1% of the patients, respectively. The proportions of patients receiving target doses of guideline-directed medications were 24.4% for RAS inhibitors, 11.0% for beta-blockers, and 11.1% for MRAs. Overall, 491 patients (46.2%) were treated with triple therapy, 353 patients (33.2%) were treated with any two classes of HF medications, and 218 patients (20.6%) were receiving only one class of HF medication or not receiving any HF medication. Patient-related factors comprising older age, New York Heart Association functional class, rural living, presence of hypertension, and history of myocardial infarction were independently associated with the use or non-use of GDMT. During the median 24-month period, the primary composite endpoint occurred in 362 patients (34.1%), and 177 of 1062 (16.7%) patients died. Patients treated with two or three classes of HF medications had a decreased risk of hospitalization for HF or cardiovascular death compared with those patients receiving ≤1 class of HF medication [hazard ratio (HR): 0.65; 95% confidence interval (CI): 0.49-0.85; P = 0.002, and HR: 0.61; 95% CI: 0.47-0.79; P < 0.001, respectively]. CONCLUSIONS: The real-life SMYRNA study provided comprehensive data about the clinical factors associated with the non-use of GDMT and showed that suboptimal GDMT is associated with an increased risk of hospitalization for HF or cardiovascular death in patients with HFrEF.

Gender-Related Differences in Patients with Acute Heart Failure: Observation from the Journey Heart Failure-Turkish Population Study.

BACKGROUND: Gender-related clinical variations in patients with acute heart failure have been described in previous studies. However, there is still a lack of research on gender differences in patients hospitalized for acute heart failure in Türkiye. The aim of this study is to compare the clinical features, in-hospital approaches, and outcomes of male and female patients hospitalized for acute heart failure. METHODS: Differences in clinical characteristics, medication prescription, hospital management, and outcomes between males and females with acute heart failure were investigated from the Journey Heart Failure-Turkish Population study. RESULTS: Nine hundred eighteen patients (57.2%) were men and 688 (42.8%) were women. Women were older than men (70.48 ± 13.20 years vs. 65.87 ± 12.82 years; P <.001). The frequency of comorbidities such as hypertension (72.7% vs. 62.4%, P <.001), diabetes (46.5% vs. 38.5%, P = .001), atrial fibrillation (46.5% vs. 33.4%, P <.001), New York Heart Association class III-IV symptoms (80.6% vs. 71.2%, P =.001), and dyspnea in the rest (73.8% vs. 68.3%, P =.044) were more common in women on admission. Male patients were more frequently hospitalized with reduced left ventricular ejection fraction (51.0% vs. 72.4%, P <.001). In-hospital mortality was higher among female patients (9.3% vs. 6.4%, P =.022). Higher New York Heart Association class, lower estimated glomerular filtration rate, higher N-terminal pro-B type natriuretic peptide on admission, and mechanical ventilation usage were the independent parameters of in-hospital mortality, whereas the female gender was not. CONCLUSION: Our study clearly demonstrated the diversity in presentation, management, and in-hospital outcomes of acute heart failure between male and female patients. Although left ventricular systolic functions were better in female patients, in-hospital mortality was higher. Recognizing these differences in the management of heart failure in different sexes will serve better results in clinical practice.

Risk Assessment Tool Implementation in Congenital Heart Disease-Associated Pulmonary Arterial Hypertension.

BACKGROUND: Risk assessment is recommended for patients with congenital heart disease-associated pulmonary arterial hypertension. This study aims to compare an abbreviated version of the risk assessment strategy, noninvasive French model, and an abridged version of the Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management 2.0 risk score calculator, Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2. METHODS: We enrolled a mixed prevalent and incident cohort of patients with congenital heart disease-associated pulmonary arterial hypertension (n = 126). Noninvasive French model comprising World Health Organization functional class, 6-minute walk distance, and N-terminal pro-hormone of brain natriuretic peptide or brain natriuretic peptide was used. Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2 includes functional class, systolic blood pressure, heart rate, 6-minute walk distance, brain natriuretic peptide/N-terminal pro-hormone of brain natriuretic peptide, and estimated glomerular filtration rate. RESULTS: The mean age was 32.17 ± 16.3 years. The mean follow-up was 99.41 ± 58.2 months. Thirty-two patients died during follow-up period. Most patients were Eisenmenger syndrome (31%) and simple defects (29.4%). Most patients received monotherapy (76.2%). Most patients were World Health Organization functional class I-II (66.6%). Both models effectively identified risk in our cohort (P =.0001). Patients achieving 2 or 3 noninva-sive low-risk criteria or low-risk category by Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2 at follow-up had a significantly reduced risk of death. Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2 approximates noninvasive French model at discriminating among patients based on c-index. Age, high risk by Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2, and the presence of 2 or 3 low-risk criteria by noninvasive French model emerged as an independent predictors of mortality (multivariate hazard ratio: 1.031, 95% CI: 1.005-1.058, P =.02; hazard ratio: 4.258, CI: 1.143-15.860, P =.031; hazard ratio: 0.095, CI: 0.013-0.672, P =.018, respectively). CONCLUSIONS: Both abbreviated risk assessment tools may provide a simplified and robust method of risk assessment for congenital heart disease-associated pulmonary arterial hypertension. Patients not achieving low risk at follow-up may benefit from aggressive use of available therapies.

Percutaneous Treatment of Left Main Coronary Artery Compression in a Pulmonary Artery Hypertension Patient Associated with Atrial Septal Defect.

Pulmonary arterial hypertension is still a fatal disease persisting with poor prognosis, despite all the advances in treatment (new agents and new combination strategies) in recent years. Patients present with different symptoms which are not specific to the disease (dyspnea, angina, palpitation, and syncope). Angina may occur secondary to myocardial ischemia due to increased right ventricular after load (oxygen supply and demand mismatch) or external compression on the left main coronary artery. Left main coronary artery compression is associated with post-exercise sudden cardiac death in pulmonary arterial hypertension patients. It should be kept in mind in the differential diagnosis of angina in patients with pulmonary arterial hypertension and should be treated immediately. Here, we report a pulmonary arterial hypertension patient associated with secundum-type atrial septal defect presented with ostial left main coronary artery compression caused by an enlarged pulmonary artery and treated with intravascular ultrasound-guided percutaneous coronary intervention.

Long-Term Prognosis of Patients with Heart Failure: Follow-Up Results of Journey HF-TR Study Population.

BACKGROUND: Despite advances in therapeutic management of patients with heart failure, there is still an increasing morbidity and mortality all over the world. In this study, we aimed to present the 3-year follow-up outcomes of patients included in the Journey HF-TR study in 2016 that has evaluated the clinical characteristics and management of patients with acute heart failure admitted to the hospital and present a national registry data. METHODS: The study was designed retrospectively between November 2016 and December 2019. Patient data included in the previously published Journey HF-TR study were used. Among 1606 patients, 1484 patients were included due to dropout of 122 patients due to inhospital death and due to exclusion of 173 due to incomplete data. The study included 1311 patients. Age, gender, concomitant chronic conditions, precipitating factors, New York Heart Association, and left ventricular ejection fraction factors were adjusted in the Cox regression analysis. RESULTS: During the 3-year follow-up period, the ratio of hospitalization and mortality was 70.5% and 52.1%, respectively. Common causes of mortality were acute decompensation of heart failure and acute coronary syndrome. Angiotensin receptor blockers, betablockers, statin, and sacubitril/valsartan were found to reduce mortality. Hospitalization due to acute decompensated heart failure, acute coronary syndrome, lung diseases, oncological diseases, and cerebrovascular diseases was associated with the increased risk of mortality. Implantation of cardiac devices also reduced the mortality. CONCLUSIONS: Despite advances in therapeutic management of patients with heart failure, our study demonstrated that the long-term mortality still is high. Much more efforts are needed to improve the inhospital and long-term survival of patients with chronic heart failure.

Evaluation of primary and accessory respiratory muscles and their influence on exercise capacity and dyspnea in pulmonary arterial hypertension.

BACKGROUND: Skeletal and respiratory muscle disfunction has been described in pulmonary arterial hypertension (PAH), however, involvement of accessory respiratory muscles and their association with symptomatology in PAH is unclear. OBJECTIVES: To assess the primary and accessory respiratory muscles and their influence on exercise tolerance and dyspnea. METHODS: 27 patients and 27 healthy controls were included. Serratus anterior (SA), pectoralis muscles (PM) and sternocleidomastoid (SCM) muscle strength were evaluated as accessory respiratory muscles, maximal inspiratory (MIP) and expiratory pressures (MEP) as primary respiratory muscles, and quadriceps as peripheral muscle. Exercise capacity was evaluated with 6-min walk test (6MWT), dyspnea with modified Medical Council Research (MMRC) and London Chest Activity of Daily Living (LCADL) scales. RESULTS: All evaluated muscles, except SCM, and 6MWT were decreased in patient group (p < 0.01). SA was the most affected muscle among primary and accessory respiratory muscles (Cohen's-d = 1.35). All evaluated muscles significantly correlated to 6MWT (r = 0.428-0.525). A multivariate model including SA, SCM and MIP was the best model for predicting 6MWT (R = 0.606; R2 = 0.368; p = 0.013) and SA strength had the most impact on the 6MWT (B = 1.242; ß = 0.340). None of the models including respiratory muscles were able to predict dyspnea, however PM and SA strength correlated to LCADL total (r = -0.493) and MMRC (r = -0.523), respectively. CONCLUSION: SCM may be excessively used in PAH since it retains its strength. Considering the relationship of accessory respiratory muscles with exercise tolerance and dyspnea, monitoring the strength of these muscles in the clinical practice may help providing better management for PAH.

Cre8 Drug Eluting Stent Performance in Daily Cardiology Practice.

Background: In patients undergoing percutaneous coronary intervention (PCI), drug eluting stents (DES) are currently the standard of care. Stent design and alloy composition, biocompatibility of the drug-eluting polymer coating, the antiproliferative agent properties and release are the three main characteristics that affects DES performance. Cre8 (Alvimedica, Istanbul, Turkey) is a polymer-free amphilimus-eluting stents (PF-AES). In this study, we aimed to investigate the clinical efficacy and safety of Cre8 DES in daily cardiology practice. Methods: Patients presenting with chronic coronary syndrome (CCS) or acute coronary syndrome (ACS) including unstable angina pectoris (USAP), myocardial infarction with and without ST-segment elevation and treated with PCI using Cre8 DES between December 2015 and 2016 were retrospectively analyzed in this study. Results: Between December 2015 and 2016, 808 lesions of 664 patients treated with Cre8 DES in a single center were included in this retrospective analysis. The mean age of study group was 60 years (between 33 and 93 years) and were predominantly consisting of male patients (79.4%). The median follow-up duration was 487 days (min: 30 days, max: 919 days) and two-thirds of all patients presented with ACS. The culprit lesion was on left anterior descending artery (LAD) (40.5%) and right coronary artery (RCA) (25.9%) in most of the patients. The procedural success rate was 97.3%. Most of the lesions were type B1 (40.6%) according to American College of Cardiology/American Heart Association (ACC/AHA) coronary lesion classification. The device oriented primary end-point defined as target lesion failure (TLF) occurred in 52 (6.4%) of 808 lesions. The primary safety end-point was cardiac death in 20 patients (3.0%) and target vessel myocardial infarction in 2 patients (0.3%). Target vessel revascularization (TVR) occurred in 29 patients (4.4%) as primary safety endpoint. Multivariable logistic regression analysis revealed diabetes mellitus and ejection fraction as the predictors of mortality and device oriented primary end-point. Conclusions: This trial revealed clinical efficacy and safety of Cre8 stents in real world practice. Device oriented primary end points were similar with previous studies which are randomized, open label in nature and showed the efficacy and safety of Cre8 stent towards latest generation DES.

The Safety and Tolerability of Nebivolol in Hypertensive Patients with Coronary Artery Disease and Left Ventricular Ejection Fraction ≥ 40%: A Population-Based Cohort Study (Nebivolol-TR Study).

BACKGROUND: This study aimed to assess the safety and tolerability of nebivolol in hypertensive patients with coronary artery disease and left ventricular ejection fraction ≥ 40% in a Turkish cohort. METHODS: A total of 1015 hypertensive patients and coronary artery disease with left ventricular ejection fraction ≥ 40% were analyzed from 29 different centers in Turkey. Primary outcomes were the mean change in blood pressure and heart rate. Secondary outcomes were to assess the rate of reaching targeted blood pressure (<130/80 mmHg) and heart rate (<60 bpm) and the changes in the clinical symptoms (angina and dyspnea). Adverse clinical events and clinical outcomes including cardiovascular mortality, cardiovascular hospital admissions, or acute cardiac event were recorded. RESULTS: The mean age of the study population was 60.3 ± 11.5 years (male: 54.2%). During a mean follow-up of 6 months, the mean change in blood pressure was -11.2 ± 23.5/-5.1 ± 13.5 mmHg, and the resting heart rate was -12.1 ± 3.5 bpm. Target blood pressure and heart rate were achieved in 76.5% and 37.7% of patients. Angina and functional classifications were improved by at least 1 or more categories in 31% and 23.2% of patients. No serious adverse events related to nebivolol were reported. The most common cardiovascular side effect was symptomatic hypotension (4.2%). The discontinuation rate was 1.7%. Cardiovascular hospital admission rate was 5% and hospitalization due to heart failure was 1.9% during 6 months' follow-up. Cardiovascular mortality rate was 0.1%. CONCLUSION: Nebivolol was well tolerated and safe for achieving blood pressure and heart rate control in hypertensive patients with coronary artery disease and heart failure with preserved or mildly reduced ejection fraction.

Prevalence of musculoskeletal pain and its impact on quality of life and functional exercise capacity in patients with pulmonary arterial hypertension.

BACKGROUND: In pulmonary arterial hypertension (PAH), pathophysiological consequences of the disease and the drugs used to treat PAH may adversely affect musculoskeletal system. Aim of the study was to evaluate musculoskeletal pain prevalence and its impact on quality of life (QoL) and exercise capacity in PAH patients. METHODS: 61 PAH patients were evaluated with Nordic Musculoskeletal Questionnaire (NMQ) for musculoskeletal pain presence, EmPHasis-10 and Minnesota Living with Heart Failure Questionnaire (MLHFQ) for QoL, 6-min walk test (6MWT) for functional exercise capacity and International Physical Activity Questionnaire- Short Form (IPAQ-SF) for physical activity participation. RESULTS: 77% of PAH patients reported musculoskeletal pain. Pain prevalence was highest at low back (38%), followed by knees (36%), shoulders (36%) and neck (33%). Hemodynamic indicators of PAH severity were associated with pain presence in various parts of the body. Patients receiving any PAH-specific drug were more likely to experience pain compared to the patients whose drug therapy has not yet been initiated (RR = 1.6-2.0). Pain presence in neck, shoulder, low back and knees significantly correlated to worse QoL scores in both EmPHasis-10 and MLHFQ (p < 0.05). Pain presence in knees had the strongest influence on QoL, and it was the only significant correlate of 6MWT (r = -0.424) and IPAQ-SF (r = -0.264) (p < 0.05). CONCLUSIONS: Musculoskeletal pain is a common complaint in PAH patients, which significantly impairs QoL and physical functioning. Treatment strategies should include a more comprehensive assessment for musculoskeletal pain complaints of these patients and address pain presence accordingly, which may help providing a better management for PAH.
