Functional capacity, physical activity, and arterial stiffness in patients with systemic sclerosis.

OBJECTIVES: Systemic sclerosis (SSc) is a complex immune-mediated connective tissue disease, involving skin manifestations, vascular features, and organ-based complications that may affect functional capacity and physical activity. Functional capacity and physical activity are associated with arterial stiffness; however, this relationship has not been evaluated in patients with SSc. Therefore, the objective of this study was to investigate the association of functional capacity and physical activity with arterial stiffness in patients with SSc. METHODS: Sixty-five patients with SSc were enrolled in this cross-sectional study. Arterial stiffness was evaluated with carotid-femoral pulse wave velocity (cf-PWV). Functional capacity and physical activity were assessed with a six-min walk test (6MWT) and International Physical Activity Questionnaire-Short Form (IPAQ-SF), respectively. RESULTS: All participants were women, and the mean age was 54.91 ± 11.18 years. 6MWT distance and IPAQ-SF were inversely associated with cf-PWV in crude analysis (p < 0.05). The relationship between 6MWT distance and cf-PWV was maintained in the fully adjusted model (ß = - 0.007, 95% CI, - 0.013 to 0.000). Similarly, the association between IPAQ-SF and cf-PWV remained significant in the fully adjusted model (ß = - 0.001, 95% CI, - 0.002 to - 0.001). CONCLUSION: The present study indicates that functional capacity and self-reported physical activity are independently associated with arterial stiffness in patients with SSc. Exercise interventions targeted to increase functional capacity and physical activity may help to regulate arterial stiffness in patients with SSc. Key Points • Arterial stiffness is an independent predictor of cardiovascular risk. • SSc patients exhibit decreased exercise capacity and functional capacity. • The association of functional capacity and physical activity with arterial stiffness in patients with SSc is unknown. • Functional capacity and self-reported physical activity are independently associated with arterial stiffness in patients with SSc.

Current barriers and recommendations on the diagnosis of transthyretin amyloid cardiomyopathy: a Delphi study.

Objectives: This study has been conducted to investigate the non-invasive diagnostic journey of patients with a transthyretin amyloid cardiomyopathy (aTTR-CM) in Turkey, identify the challenges and uncertainties encountered on the path to diagnosis from the perspectives of expert physicians, and develop recommendations that can be applied in such cases. Methods: This study employed a three-round modified Delphi method and included 10 cardiologists and five nuclear medicine specialists. Two hematologists also shared their expert opinions on the survey results related to hematological tests during a final face-to-face discussion. A consensus was reached when 80% or more of the panel members marked the "agree/strongly agree" or "disagree/strongly disagree" option. Results: The panelists unanimously agreed that the aTTR-CM diagnosis could be established through scintigraphy (using either 99mTc-PYP, 99mTc-DPD, or 99mTc-HMPD) in a patient with suspected cardiac amyloidosis (CA) without a further investigation if AL amyloidosis is ruled out (by sFLC, SPIE and UPIE). In addition, scintigraphy imaging performed by SPECT or SPECT-CT should reveal a myocardial uptake of Grade ≥2 with a heart-to-contralateral (H/CL) ratio of ≥1.5. The cardiology panelists recommended using cardiovascular magnetic resonance (CMR) and a detailed echocardiographic scoring as a last resort before considering an endomyocardial biopsy in patients with suspected CA whose scintigraphy results were discordant/inconclusive or negative but still carried a high clinical suspicion of aTTR-CM. Conclusion: The diagnostic approach for aTTR-CM should be customized based on the availability of diagnostic tools/methods in each expert clinic to achieve a timely and definitive diagnosis.

Clinical Heterogeneity in Patients with Long QT Syndrome and Segregation of Single Nucleotide Variants and Clinical Symptoms in 17 Affected Families.

Introduction: Long QT syndrome (LQTS) is a disorder of ventricular myocardial repolarization characterized by a prolonged QT interval on the electrocardiogram. It increases the risk of ventricular arrhythmias, which can cause syncope or sudden cardiac death. In this study, we study the genotype-phenotype relationships of patients referred to us with suspected arrhythmia syndrome. Methods: Seventeen cases and their twenty relatives were evaluated. Next-generation sequencing analysis was performed for 17 LQTS-related genes. Results: We detected seventeen single nucleotide variants (SNVs) with potential pathogenic significance in 26 of the 36 subjects analyzed. KCNH2 c.172G>A, KCNQ1 c.1768G>A, ANK2 c.4666A>T, c.1484_1485delCT, KCNH2 c.1888G>A were reported as pathogenic or likely pathogenic in HGMD variant classification database. Conclusion: Current study pointed out that early diagnosis can be life-saving for patients and their families by taking family history and detailed examination. Also, we highlight the clinical heterogeneity of arrhythmia syndrome through a patient with a dual phenotype.

Heritable Pulmonary Arterial Hypertension Diagnosed during the Postpartum Period: A Case Report and Literature Review.

Approximately one-third of bone morphogenic protein receptor-2 (BMPR2) mutation carriers develop pulmonary arterial hypertension (PAH), which indicates that additional risk factors are needed for the manifestation of the disease. It is questionable whether pregnancy is a risk factor for PAH development in these patients. We represent a 30-year-old woman with a heterozygous BMPR2 mutation who was diagnosed with PAH during the postpartum period and reviewed the literature in this report. We also discussed the possible underlying mechanisms that might have resulted in PAH development during pregnancy in BMPR2 mutation carriers.

Effects of Inspiratory Muscle Training in Patients With Pulmonary Hypertension.

The study aimed to examine the effects of inspiratory muscle training (IMT) in patients with pulmonary hypertension (PH). A total of 24 patients with PH were included in the randomized controlled evaluator-blind study. IMT was performed at 40% to 60% of the maximal inspiratory pressure for 30 min/d, 7 d/wk (1 day supervised) for 8 weeks. Respiratory muscle strength, dyspnea, diaphragm thickness (DT), pulmonary functions, 24-hour ambulatory blood pressure (BP), arterial stiffness, exercise capacity, upper extremity functional exercise capacity, physical activity levels, fatigue, anxiety-depression levels, activities of daily living (ADL), and quality of life were evaluated. A total of 24 patients (treatment = 12, control = 12) completed the 8-week follow-up. There was no significant difference between the patient groups in terms of demographic and clinical characteristics (p >0.05). Considering the change between the groups in the treatment and control groups, brachial and central BP, dyspnea, respiratory muscle strength, DT in total lung capacity, knee extension muscle strength, functional exercise capacity, upper extremity functional exercise capacity, physical activity, ADL, fatigue, anxiety, and quality of life improved in favor of the IMT group (p <0.05). In conclusion, IMT has improved brachial and central BP, dyspnea, respiratory muscle strength, DT in total lung capacity, knee extension muscle strength, functional exercise capacity, upper extremity functional exercise capacity, physical activity, ADL, fatigue, anxiety, and quality of life compared with the control group. IMT is an effective method in cardiopulmonary rehabilitation for patients with PH.

Effects of high intensity interval-based inspiratory muscle training in patients with heart failure: A single-blind randomized controlled trial.

BACKGROUND: Given the promising effects of inspiratory muscle training (IMT), determining the most appropriate IMT protocol will optimize the training benefits. OBJECTIVES: The objective of this study was to determine the effects of high intensity interval-based inspiratory muscle training (H-IMT) on cardiovascular, pulmonary, physical, and psychosocial functions in patients with heart failure and reduced ejection fraction (HFrEF). METHODS: Thirty-four patients with HFrEF were randomly assigned to the H-IMT or control group for 3 days/week, 8 weeks training period. The H-IMT group performed IMT at least 70% of the maximal inspiratory pressure, whereas the control group performed unloaded IMT. Each session occurred 7 sets with a total of 21 min consisting of 2-min training and 1-min interval. Heart rate variability (HRV), arterial stiffness, respiratory muscle strength and endurance, diaphragm thickness, quadriceps strength, functional capacity, frailty, dyspnea, fatigue, disease-specific health-related quality of life (HRQoL), and generic HRQoL were evaluated at baseline and after 8 weeks training period by blinded assessors. RESULTS: Statistically significant between-group differences were observed in the time domain parameters of HRV, arterial stiffness, inspiratory and quadriceps muscle strength, respiratory muscle endurance, diaphragm thickness, functional capacity, frailty, dyspnea, fatigue, and disease-specific HRQoL in favor of the H-IMT group (p<0.05). CONCLUSIONS: H-IMT is an effective protocol for improving cardiac autonomic function, arterial stiffness, inspiratory and quadriceps muscle strength, respiratory muscle endurance, diaphragm thickness, functional capacity, frailty, dyspnea, fatigue, and disease-specific quality of life in patients with HFrEF. CLINICAL TRIAL REGISTRATION: NCT04839211.

The Frequency of Fabry Disease in Patients with Cardiac Hypertrophy of Various Phenotypes Including Prominent Papillary Muscle: The TUCARFAB Study in Turkey.

BACKGROUND: The present study aimed to identify the frequency of Fabry disease in patients with cardiac hypertrophy of unknown etiology and to evaluate demographic and clinical characteristics, enzyme activity levels, and genetic mutations at the time of diagnosis. METHODS: This national, multicenter, cross-sectional, single-arm, observational registry study was conducted in adult patients with a clinical echocardiographic diagnosis of left ventricular hypertrophy and/or the presence of prominent papillary muscle. In both genders, genetic analysis was performed by DNA Sanger sequence analysis. RESULTS: A total of 406 patients with left ventricular hypertrophy of unknown origin were included. Of the patients, 19.5% had decreased enzyme activity (≤2.5 nmol/mL/h). Although genetic analysis revealed GLA (galactosidase alpha) gene mutation in only 2  patients (0.5%), these patients were considered to have probable but not 'definite Fabry disease' due to normal lyso Gb3 levels and gene mutations categorized as variants of unknown significance. CONCLUSION: The prevalence of Fabry disease varies according to the characteristics of the population screened and the definition of the disease used in these trials. From cardiology perspective, left ventricular hypertrophy is the major reason to consider screening for Fabry disease. Enzyme testing, genetic analysis, substrate analysis, histopathological examination, and family screening should be performed, when necessary, for a definite diagnosis of Fabry disease. The results of this study underline the importance of the comprehensive use of these diagnostic tools to reach a definite diagnosis. The diagnosis and management of Fabry disease should not be based solely on the results of the screening tests.

Test-Retest Reliability and Validity of 1-Minute Sit-to-Stand Test in Patients With Chronic Heart Failure.

AIM: The psychometric properties of the 1-minute sit-to-stand (1STS) test have not been investigated in patients with chronic heart failure (CHF). The aim of this study was to evaluate test-retest reliability, construct validity, and minimal detectable change of the 1STS test and to investigate the physiological response to the 1STS test in patients with CHF. METHOD: Forty-three (43) patients with CHF were included. Demographic and clinical features were recorded. To investigate test-retest reliability, participants performed two 1STS tests on the same day. The correlations between the 1STS test and the 6-minute walk test (6MWT), functional class, pulmonary function, quadriceps muscle strength, and physical activity were investigated for validity. The physiological responses and symptom perception were assessed before and after both the 1STS test and 6MWT. RESULTS: Excellent test-retest reliability was found for the 1STS test, with an intraclass correlation of 0.932 (95% confidence interval 0.874-0.963). The minimal detectable change of the 1STST test was 3.7 repetitions. The 1STS test was correlated with 6MWT distance, age, functional class, pulmonary function, quadriceps muscle strength, and physical activity (p<0.05). The 1STS test showed similar changes to the 6MWT in physiological responses and symptom perception (p>0.05), except for leg fatigue (p=0.02). CONCLUSIONS: The 1STS test is reliable and valid in evaluating functional exercise capacity in patients with CHF. The 1STS test reveals similar cardiac demand to the 6MWT. The 1STS test may be considered an option when traditional tests are impractical in terms of space and time.

Comparison of physiological responses after incremental shuttle walking test and 6-minute walk test in patients with systemic sclerosis.

BACKGROUND: The 6­minute walk test (6MWT) is a commonly used to evaluate exercise capacity in patients with systemic sclerosis (SSc), but there was no study using the incremental shuttle walking test (ISWT) for assessing exercise capacity and comparing the patient's cardiorespiratory responses to these tests. The aim was to investigate the usability and determinants of the ISWT in patients with SSc and compare the physiological responses after the ISWT and 6MWT. METHODS: A total of thirty four female patients with SSc were included. Dyspnea during daily activities and knee extensor muscle strength was assessed, skin fibrosis and disease severity were recorded, and 6MWT and ISWT were carried out for the exercise capacity measurement. Pulmonary function test results were recorded from the individuals' medical records for SSc with interstitial lung disease (SSc-ILD) patients. RESULTS: The ISWT distance was significantly correlated with the 6MWT distance (p < 0.001). The 6MWT was correlated with age, modified Rodnan skin score, Medsger severity score, modified British Medical Research Council Questionnaire (mMRC) score, and knee extensor muscle strength (p < 0.05). The 6MWT was correlated with the forced expiratory volume in the first second (FEV1) (lt) and forced vital capacity (FVC) (lt) in patients with SSc-ILD (p < 0.05). The ISWT distance was correlated with age, modified Rodnan skin score, mMRC score, and knee extensor muscle strength (p < 0.05). Age, mMRC, and knee extensor muscle strength explained 33.8% of the variance in 6MWT distance, while age, mMRC, and knee extensor muscle strength explained 51.7% of the variance in the ISWT distance. CONCLUSION: Because of the higher cardiopulmonary responses, and having a more standardized procedure, the ISWT may be preferable for investigating symptom-limited exercise capacity in patients with SSc. Age, dyspnea, and knee extensor muscle strength were the determinants of exercise capacity in patients with SSc.

The Role of Non-Vitamin K Antagonist Oral Anticoagulants (NOACs) in Atrial Fibrillation: Treatment Management Based on Patient and Drug Characteristics.

Data from Turkey revealed that atrial fibrillation patient percentage under adequate anti- coagulation in Turkey is less than that in other countries due to multiple parameters such as treatment adherence problems, failure to follow guideline recommendations, negative perspective on the use of new drugs, drug costs, and payment conditions. The aim of this article is to provide physicians with a compiled resource that focuses on the differences between non-vitamin K antagonist oral anticoagulants and heterogeneity of atrial fibrilla- tion patients by reviewing the global and national data from a multidisciplinary perspective and provide guidance on the choice of non-vitamin K antagonist oral anticoagulants in atrial fibrillation patients. A gastroenterologist, 2 neurologists, and 11 cardiologists from university and training and research hospitals in Turkey who are experienced in atrial fibrillation and non-vitamin K antagonist oral anticoagulant treatments gathered in 3 separate meetings to identify the review topics and evaluate the outcomes of the systematic literature search. Based on the pharmacological characteristics, clinical studies, and real-world data compari- sons, it has been revealed that non-vitamin K antagonist oral anticoagulants are not similar. Thromboembolism and bleeding risks, renal and hepatic functions, coexisting conditions, and concomitant drug usage have been shown to affect the levels of benefits gained from non-vitamin K antagonist oral anticoagulant in atrial fibrillation patients. Although Turkish patients with atrial fibrillation have been observed to be younger, they are more likely to have coexisting cardiovascular conditions compared to the atrial fibrillation patients in other countries. Selection of an appropriate non-vitamin K antagonist oral anticoagulant in line with the available evidence and recent guidelines will provide substantial benefits to atrial fibrillation patients.

Evaluation of Treatment Safety in Patients with Atrial Fibrillation on Edoxaban Therapy in Real-Life in Turkey Study: Design and Rationale.

OBJECTIVE: Safety and effectiveness of edoxaban was demonstrated in phase III, Effective Anticoagulation with Factor Xa Next Generation in Atrial Fibrillation-Thrombolysis in Myocardial Infarction 48 (ENGAGE-AF-TIMI 48) trial and is being confirmed in the post-authorization Edoxaban Treatment in routiNe clinical prActice for patients with Atrial Fibrillation in Europe (ETNA-AF-Europe) study in patients with atrial fibrillation. However, any post-authoriza tion safety study focusing on the safety of edoxaban treatment in Turkey with a prospective design has not been performed yet. The Evaluation of Treatment Safety in Patients with Atrial Fibrillation on Edoxaban Therapy in Real-Life in Turkey (ETAF-TR) study is designed to evaluate the safety and effectiveness of edoxaban treatment in atrial fibrillation in routine practice. The present article describes the design and rationale for the ETAF-TR Study. METHODS: The ETAF-TR (NCT04594915) is a national, multicenter, prospective, observational study that enrolled 858 patients from 32 centers. The primary outcome of the ETAF-TR study is any overt bleeding (consisting of major bleeding or clinically relevant nonmajor bleeding or any bleeding that does not meet this definition but is considered as overt bleeding by the par ticipating physician). Effectiveness, treatment persistence, and posology will also be evaluated in an explorative manner. The overall duration of follow-up will be 1 year; the first patient was enrolled in August 2020. CONCLUSIONS: Results of ETAF-TR will add data from clinical practice to those from ENGAGE-AF trial and also ETNA-AF study. Comparing their results will enable to test the external validity of ENGAGE-AF trial in the country conditions.

Extrapulmonary features of post-COVID-19 patients: muscle function, physical activity, mood, and sleep quality.

BACKGROUND: Coronavirus disease 2019 (COVID-19) represents a wide range of clinical manifestations, even if mild disease severity. It has been known that pulmonary function is affected by COVID-19 during infection and mid-to-long term. However, there is inadequate evidence about extrapulmonary features in post-COVID-19 patients. AIMS: This study aimed to investigate extrapulmonary features in post-COVID-19 patients who recovered from mild and moderate disease severity in the mid-term. METHODS: This cross-sectional study was carried out after at least 12 weeks from the COVID-19 diagnosis. Disease severity was defined using criteria for clinical severity of confirmed COVID-19 pneumonia. The peripheral muscle strength was measured using the dynamometer. Physical performance was assessed with five times sit-to-stand and 4-m gait speed. Physical activity level (PAL), mood, and sleep quality were assessed with the International Physical Activity Questionnaire, Hospital Anxiety, and Depression Scale, and Pittsburgh Sleep Quality Index, respectively. RESULTS: A total of 48 participants with post-COVID-19 (39.2 ± 7.9 years, 54.2% women) were included in the study. Handgrip and quadriceps weakness was observed in 39.6% and 35.4% of the participants, respectively. PAL was low in 39.6%, moderate in 33.3%, and high in 27.1% of the participants. Anxiety, depression, and poor sleep quality were observed in 33.3%, 29.2%, and 50% of the participants, respectively. CONCLUSIONS: Extrapulmonary features are adversely affected in a substantial proportion of post-COVID-19 patients who recovered from mild and moderate disease severity in the mid-term. Comprehensive assessment and appropriate intervention strategies should also be considered for non-severe post-COVID-19 patients.

Determinants of gait speed in patients with heart failure with reduced ejection fraction.

OBJECTIVE: Given the prognostic significance of gait speed, there is insufficient evidence about possible functional determinants of gait speed in patients with heart failure with reduced ejection fraction (HFrEF). Therefore, the objective of this study was to investigate the functional determinants of gait speed in patients with HFrEF. METHODS: Fifty-nine patients with HFrEF participated in this cross-sectional study. Demographic and clinical characteristics were recorded. The gait speed was determined with a 4-meter walking test. Dyspnea perception was assessed with the modified medical research council (mMRC) scale. Functional capacity was evaluated with a 6-minute walk test (6MWT). The five times sit-to-stand (5-STS) test and the Berg Balance Scale (BBS) were used to measure functional mobility and balance. Physical activity was evaluated with the International Physical Activity Questionnaire (IPAQ) Short-Form. RESULTS: Gait speed was correlated with age (r=-0.368, p=0.004), NYHA functional class (r=-0.438, p=0.001), mMRC score (r=-0.422, p=0.001), 6MWT (r=0.650, p<0.001), 5STS (r=-0.506, p<0.001), BBS (r=0.586, p<0.001), IPAQ (r=0.305, p=0.019) and IPAQ-Sitting time (r=-0.327, p=0.011). On multiple linear regression analysis, the 6MWT distance and BBS were independent determinants of the usual gait speed in patients with HFrEF, accounting for 44.4% of the variance. CONCLUSION: This study indicates that functional capacity and balance are independent functional determinants of gait speed in patients with HFrEF.

Assessment of psychometric properties, cross-cultural adaptation, and translation of the Turkish version of the ICU mobility scale

Background/aim: The aim of the study was to carry out the cultural adaptation and translation of the ICU mobility scale (IMS) into Turkish and research the psychometric properties. Materials and methods: This study was based on methodological design. The IMS was translated from English to the Turkish through a regularised translation process. Two physiotherapists assessed patients independently in the coronary intensive care unit. The measures such as construct validity, intra and interrater reliability, and internal consistency of the IMS Turkish version were assessed. Results: A total of 70 intensive care patients were included in the study. The intrarater and interrater reliability of the IMS was excellent. The weighted Kappa value was 0.92 (0.87­0.96) for the intrarater reliability, and 0.87 (0.80­0.93) for the interrater reliability. There were significant correlations between the IMS and functional status score for the intensive care unit (r = 0.83), Perme intensive care unit mobility score (r = 0.84), Katz activities of daily living (r = 0.73), handgrip strength (r = 0.62), knee extension strength (r = 0.46), and age (r = ­0.44). Conclusion: This study suggests that the IMS Turkish version is a reliable and valid scale for assessing functional status and mobility level in ICU patients.

Cardiac phenotype in familial partial lipodystrophy.

OBJECTIVES: LMNA variants have been previously associated with cardiac abnormalities independent of lipodystrophy. We aimed to assess cardiac impact of familial partial lipodystrophy (FPLD) to understand the role of laminopathy in cardiac manifestations. STUDY DESIGN: Retrospective cohort study. METHODS: Clinical data from 122 patients (age range: 13-77, 101 females) with FPLD were analysed. Mature human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) from a patient with an LMNA variant were studied as proof-of-concept for future studies. RESULTS: Subjects with LMNA variants had a higher prevalence of overall cardiac events than others. The likelihood of having an arrhythmia was significantly higher in patients with LMNA variants (OR: 3.77, 95% CI: 1.45-9.83). These patients were at higher risk for atrial fibrillation or flutter (OR: 5.78, 95% CI: 1.04-32.16). The time to the first arrhythmia was significantly shorter in the LMNA group, with a higher HR of 3.52 (95% CI: 1.34-9.27). Non-codon 482 LMNA variants were more likely to be associated with cardiac events (vs. 482 LMNA: OR: 4.74, 95% CI: 1.41-15.98 for arrhythmia; OR: 17.67, 95% CI: 2.45-127.68 for atrial fibrillation or flutter; OR: 5.71, 95% CI: 1.37-23.76 for conduction disease). LMNA mutant hiPSC-CMs showed a higher frequency of spontaneous activity and shorter action potential duration. Functional syncytia of hiPSC-CMs displayed several rhythm alterations such as early afterdepolarizations, spontaneous quiescence and spontaneous tachyarrhythmia, and significantly slower recovery in chronotropic changes induced by isoproterenol exposure. CONCLUSIONS: Our results highlight the need for vigilant cardiac monitoring in FPLD, especially in patients with LMNA variants who have an increased risk of developing cardiac arrhythmias. In addition, hiPSC-CMs can be studied to understand the basic mechanisms for the arrhythmias in patients with lipodystrophy to understand the impact of specific mutations.

Acute effects of inspiratory muscle training at different intensities in healthy young people.

BACKGROUND: Understanding the acute effects of inspiratory muscle training (IMT) at different intensities on the autonomic nervous system, arterial stiffness, and blood pressure in healthy young people will be important in the constitution of appropriate IMT prescriptions. AIMS: To investigate the acute effects of IMT at different intensities on autonomic function, arterial stiffness, and blood pressure in healthy young people METHODS: Thirty-six healthy participants were enrolled in this crossover study. All participants randomly performed IMT sessions, which consisted of diaphragmatic breathing exercise (DBE), 10%, 30%, and 60% of maximal inspiratory pressure (MIP) on consecutive days. Autonomic function and arterial stiffness were assessed by measuring heart rate variability (HRV) and aortic pulse wave velocity (AoPWV), respectively. HRV, AoPWV, and blood pressure were recorded before and immediately after each IMT session. RESULTS: There was no significant difference in the baseline measurements between IMT sessions (p > 0.05). Heart rate (HR) significantly decreased after DBE and IMT at 10% of MIP (p < 0.05). All time domain parameters of HRV significantly improved after DBE compared with the baseline (p < 0.05). There was no difference in the frequency domain of HRV after the IMT sessions (p > 0.05). AoPWV significantly increased after IMT at 60% of MIP (p < 0.05). Mean arterial pressure significantly changed after DBE and IMT at 60% of MIP (p < 0.05). CONCLUSIONS: A single session of DBE positively affects autonomic function and blood pressure, while IMT at 60% of MIP increases arterial stiffness. The different intensities of IMT have various impacts on autonomic function, arterial stiffness, and blood pressure. TRIAL REGISTRATION: NCT03788356.

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.

Balance performance in patients with heart failure.

BACKGROUND: It has been suggested that patients with heart failure (HF) have an increased fall rate. Although balance is one of the most important risk factors for fall, there is not sufficient information about balance in HF. OBJECTIVE: To compare static, dynamic and functional balance between patients with HF and healthy controls. METHODS: Twenty-seven patients with HF and 22 healthy controls were recruited in this study. The Unilateral Stance (US) and Limits of Stability (LOS) tests were used to measure static and dynamic balance, respectively. Functional balance was assessed with Berg Balance Scale. RESULTS: There was no significant difference in age, gender and body mass index between the groups (p > 0.05). There was a significant difference in US with open eyes between the groups (p < 0.05). Reaction time (backward and left), endpoint excursion (backward), maximum excursion (forward and backward) and directional control (forward and right) variables of LOS were significantly different between the groups (p < 0.05). CONCLUSIONS: Patients with HF have impaired static, dynamic and functional balance. Considering the balance impairment, a comprehensive balance assessment performed and balance training should be included in the management of HF as a part of the cardiac rehabilitation program.
