RESUMO
BACKGROUND: Conflicting results have been published considering the diagnostic performance of head-up tilt test (HUTT) in patients with hypertrophic cardiomyopathy (HCM). We aimed to conduct a meta-analysis to evaluate the diagnostic value of HUTT in the evaluation of unexplained syncope in patients with HCM. METHODS: We performed a structured systematic database search using the following keywords: hypertrophic cardiomyopathy, syncope, unexplained syncope, head-up tilt test, tilt table test, tilt testing, orthostatic stress, autonomic function, autonomic response. Studies in which the HUTT was used to define autonomic dysfunction in patients with syncope at baseline or without syncope were included in the final analysis. RESULTS: A total of 252 HCM patients from 6 studies (159 patients without a history of syncope and 93 with a history of syncope, respectively) were evaluated. HUTT was positive in 50 (19.84%) of 252 patients (in 21 of 93 patients (22.58%) with a history of syncope and in 29 of 159 patients (18.24%) without a history of syncope, respectively). The pooled total sensitivity and specificity of the HUTT for detecting syncope were 22.1% (14.8-35.1%) and 83.6% (73.2-91.6%), respectively. The summary receiver operator curve showed that HUTT had an only modest discriminative ability for syncope with an area under the curve value of 0.565 (0.246-0.794). CONCLUSION: Although HUTT has significant limitations in diagnosis of unexplained syncope in patients with HCM, it may still be used to determine hypotensive susceptibility. Other autonomic tests can be used in diagnostic workflow in this population.
RESUMO
OBJECTIVE: Chronic heart failure (CHF) management requires a multidisciplinary approach, and it's very important for primary care physicians (PCC) to cooperate with cardiology physicians in this process. In this study, we tried to reveal the awareness and expectations of PCC about CHF management. METHODS: The study was designed as a descriptive survey in a single region and included 549 PCC. Data were collected through a survey study. RESULTS: A total of 389 PCC participated in our study. Of these, 137 (35.2%) stated that they had an average of more than 40 CHF patients registered with them, and 331 (85.1%) stated that they had identified them thanks to their medical treatment. The symptoms that physicians most frequently question in CHF patients are shortness of breath (27.5%), swelling in the ankle (27%), orthopnea (23.9%) and palpitations (20.5%). The physical examination findings that they question most frequently are peripheral edema (% 29.2), tachycardia (18.5%), crepitus in the lungs (16.8%), and irregular pulse (15.2%). 203 (55.9%) of PCC stated that measurements of natriuretic peptides could be implemented in their institutions if the necessary training and opportunity were provided. Most physicians (46.8%) stated that they should be given priority in referring CHF patients; 172 of them (44.2%) stated that they received in-service training regarding CHF and 278 of them (71.5%) stated that their training was not at a sufficient level. CONCLUSION: It is clear that better results can be obtained in the management of CHF as the education level and professional experience of PHCs increases. It seems that PCC need training on CHF and need to improve the quality of communication with cardiologist's.

Head and neck tumors can rarely cause carotid sinus syndrome and this often resolves by surgical intervention or palliative chemoradiotherapy. If these modalities are not an option or are ineffective, the most preferred treatment is permanent pacemaker therapy. Here, we present the first case of cardioneuroablation treatment performed in patient with oropharyngeal squamous cell cancer who developed recurrent asystole and syncope attacks due to compression of the carotid sinus on neck movement.

OBJECTIVES: Cardiovascular diseases are also considered to increase the risk of death in COVID-19 patients. However, real-world data concerning the risk factors for death in patients with severe COVID-19 still remain vague. This study aimed to identify the potential risk factors associated with mortality in severe COVID-19 patients. METHODS: All consecutive patients admitted to the intensive care unit (ICU) of our institute for COVID-19 for severe COVID-19 pneumonia from April 1, 2020 to July 20, 2020 were included in the analysis. Patient characteristics, including complete medical history and comorbid diseases, blood test results during admission and on day 7, and clinical characteristics were compared between survivors and nonsurvivors. RESULTS: There was no significant difference between survivors and nonsurvivors regarding age, gender, and preexisting cardiovascular diseases. Moreover, the rate of the medications including angiotensin-converting enzyme (ACE) inhibitor and angiotensin receptor blockers did not differ between survivors and nonsurvivors. The peak C-reactive protein (CRP), procalcitonin, fibrinogen, and d-dimer levels and the rate for chronic renal failure were significantly higher in nonsurvivors compared with survivors. Intubated patients had a higher risk of death than the others had. CONCLUSIONS: This study failed to demonstrate a significant difference in preexisting cardiovascular diseases and cardiovascular medications between survivors and nonsurvivors who were admitted to ICU for severe COVID-19. Our findings indicate that the presence of chronic renal failure, a high peak ferritin concentration, and the need for invasive mechanical ventilation appear predictive for mortality. We propose that these risk factors should be taken into account in defining the risk status of severe COVID-19 patients admitted to the ICU.

OBJECTIVE: Failure to select the optimal left ventricular (LV) segment for lead implantation is one of the most important causes of unresponsiveness to the cardiac resynchronization therapy (CRT). In our study, we aimed to investigate the echocardiographic and clinical benefits of LV lead implantation guided by an intraoperative 12-lead surface electrocardiogram (ECG) in patients with multiple target veins. METHODS: We included 80 [42 (62.5%) male] heart failure patients who successfully underwent CRT defibrillator (CRT-D) implantation. Patients were divided into two groups. In group 1, LV lead was positioned at the site with the shortest biventricular-paced (BiV-paced) QRS duration (QRSd), as intraprocedurally measured using surface ECG. In group 2 (control), we included patients who underwent the standard unguided CRT. ECG, echocardiogram, and functional status were evaluated before and 6 months after CRT implantation in all patients. RESULTS: In group 1, BiV-paced QRSd measurements were successfully performed in 112 of 120 coronary sinus branches during CRT and an LV lead was successfully placed at the optimal site in all patients. Compared with group 2, group 1 had a significantly higher rate (85% vs. 50%, p=0.02) of response (>15% reduction in LV end-systolic volume) to CRT as well as a shorter QRSd (p<0.001) and a greater QRS shortening (ΔQRS) associated with CRT compared with baseline (p<0.001). The mean New York Heart Association functional class was significantly improved in both groups, and no significant differences were found in clinical response to CRT (85% vs. 70%, p=0.181). CONCLUSION: Surface ECG can be used to guide LV lead placement in patients with multiple target veins for improving response to CRT. Thus, it is a safe, feasible, and economic approach for CRT-D implantation.
