Gender-related clinical and management differences in patients with chronic heart failure with reduced ejection fraction.

AIM: Gender-related differences have been described in the clinical characteristics and management of patients with chronic heart failure with reduced ejection fraction (HFrEF). However, published data are conflictive in this regard. METHODS: We investigated differences in clinical and management variables between male and female patients from the ATA study, a prospective, multicentre, observational study that included 1462 outpatients with chronic HFrEF between January and June 2019. RESULTS: Study population was predominantly male (70.1%). In comparison to men, women with chronic HFrEF were older (66 ± 11 years vs 69 ± 12 years, P < .001), suffered more hospitalisations and presented more frequently with NYHA class III or IV symptoms. Ischaemic heart disease was more frequent in men, whereas anaemia, thyroid disease and depression were more frequent in women. No difference was seen between genders in the use rate of renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists, or ivabradine, or in the proportion of patients achieving target doses of these drugs. Regarding device therapies, men were more often treated with an implantable cardioverter-defibrillator (ICD) and women received more cardiac resynchronisation therapy. CONCLUSION: In summary, although management seemed to be equivalent between genders, women tended to present with more symptoms, require hospitalisation more frequently and have different comorbidities than men. These results highlight the importance of gender-related differences in HFrEF and call for further research to clarify the causes of these disparities. Gender-specific recommendations should be included in future guidelines in HFrEF.

Predictors of In-Hospital Mortality in Patients With ST-Segment Elevation Myocardial Infarction Complicated With Cardiogenic Shock.

BACKGROUND: ST-segment elevation myocardial infarction (STEMI) complicated with cardiogenic shock (CS) remains as an unresolved condition causing high morbidity and mortality despite advances in medical treatment and coronary intervention procedures. In the current study, we evaluated the predictors of in-hospital mortality of STEMI complicated with CS. METHODS: In this retrospective study, we evaluated the predictive value of baseline characteristics, angiographic, echocardiographic and laboratory parameters on in-hospital mortality of 319 patients with STEMI complicated with CS who were treated with primary percutaneous coronary intervention. Patients were divided into two groups consisting of survivors and non-survivors during their index hospitalisation period. RESULTS: The mortality rate was found to be 61.3% in the study population. At multivariate analysis after adjustment for the parameters detected in univariate analysis, chronic renal failure, Thrombolysis In Myocardial Infarction (TIMI) post percutaneous coronary intervention (PCI) ≤2, plasma glucose and lactate level, blood urea nitrogen level, Tricuspid Annular Plane Systolic Excursion (TAPSE) and ejection fraction were independent predictors of in-hospital mortality. CONCLUSIONS: Apart from haemodynamic deterioration, angiographic, echocardiographic and laboratory parameters have an impact on in-hospital mortality in patients with STEMI complicated with CS.

Successful thrombolysis of a subacute prosthetic valve thrombosis with modified ultra-slow thrombolytic therapy.

Prosthetic valve thrombosis is a serious complication of heart valve surgery. According to the recent studies, thrombolytic therapy is an important alternative therapy to the open heart surgery with successful outcomes. We present a case of a prosthetic mitral valve thrombosis who was successfully treated with modified ultra-slow thrombolytic therapy.

Left Ventricular Perforation Due to Radiofrequency Catheter Ablation for Incessant Ventricular Tachycardia in a Post-Myocardial Infarction Patient.

Left ventricular (LV) myocardial perforation is a rare complication following ventricular tachycardia (VT) ablation with radiofrequency (RF); this complication should be diagnosed and treated promptly. LV free wall rupture after elective RF ablation for sustained VT refractory to medical treatment is rarely reported in the medical literature. Herein we discuss an interesting case which contributes to the ongoing literature, regarding a patient who developed LV perforation due to RF ablation for VT which was resistant to pharmacotherapy and repeated cardioversion attempts after acute myocardial infarction.

Acute myocardial infarction with concomitant pulmonary embolism as a result of patent foramen ovale.

Acute myocardial infarction (MI) and pulmonary embolism canal one lead to life-threatening conditions such as sudden cardiac death and congestive heart failure. We discuss a case of a 74-year-old man presented to the emergency department with acute dyspnea and chest pain. Acute anterior MI and pulmonary embolism concomitantly were diagnosed. Primary percutaneous coronary intervention performed because of preliminary acute anterior MI diagnosis. Transthoracic echocardiography was performed to determine further complications caused by acute MI because patient had a continuous tachycardia and dyspnea although hemodynamically stable. Transthoracic echocardiography revealed a thrombus that was stuck into the patent foramen ovale with parts in right and left atria. Anticoagulation therapy was started; neither fibrinolytic therapy nor operation was performed because of low survey expectations of the patient's recently diagnosed primary disease stage IV lung cancer. Patient was discharged on his 20th day with oral anticoagulation and antiagregant therapy.

Incremental value of live/real time three-dimensional transesophageal echocardiography over the two-dimensional technique in the assessment of primary cardiac malignant fibrous histiocytoma.

We describe a case of primary cardiac malignant fibrous histiocytoma where live/real time three-dimensional transesophageal echocardiography added incremental value to the two-dimensional modalities. Specifically, the three-dimensional technique allowed us to delineate the true extent and infiltration of the tumor, to identify characteristics of the tumor mass suggestive of its malignant nature, and to quantitatively assess the total tumor burden.

Hypertensive emergency due to pheochromocytoma crisis complicated with refractory hemodynamic collapse.

Hypertensive emergency usually appears in older patients with previous recurrent episodes, and is among the most frequent admissions to emergency departments. A 29-year-old woman was referred to our clinic with the diagnosis of hypertensive emergency. The patient complained of severe headache, dyspnea, palpitation, diaphoresis, and confusion due to hypertensive encephalopathy. Her blood pressure was 250/150 mmHg on admission. At the referral hospital, the patient had undergone cranial CT because of her confused state and this excluded acute cerebral hemorrhage. Also at that hospital, thoracoabdominal CT for differential diagnosis depicted an adrenal mass with a necrotic core. After admission to our clinic, initial control of excessive blood pressure was not achieved despite high dose intravenous nitrate therapy. Thereafter intravenous esmolol treatment was initiated simultaneously with oral alpha blocker therapy in order to counterbalance the unopposed alpha adrenergic activity with beta blocker therapy. After 12 hours, sudden onset of hypotension developed and deepened despite IV saline, inotropic and vasopressor agents such as IV dopamine, noradrenaline and adrenaline. The patient died at the 24th hour due to hemodynamic collapse as a result of hyperadrenergic state due to possible pheochromocytoma crisis. This case is an exceptional example of hypertensive emergency secondary to fulminant pheochromocytoma crisis failing to respond to intensive antihypertensive treatment, and in which patient death was unavoidable due to uncontrolled excessive adrenergic activity which led to profound cardiogenic shock.

Oral amiodarone and propranolol in maintenance therapy of postimplantation tachycardia: An observational study.

Left ventricular assist devices (LVADs) are widely used as end-stage therapy in patients with advanced heart failure, whereas implantation increases the risks of development of sustained ventricular tachycardia at the later postimplantation stage. Therefore, this study aimed to evaluate the clinical efficacy of orally administered amiodarone and propranolol in 3 patients with ventricular tachycardia (VT) after LVAD implantation who were resistant to initial anti-antiarrhythmic drugs. This retrospective cohort study consisted of the initial evaluation of the clinical data of 14 adult patients who underwent implantation of LVAD between January 2019 and March 2021. A total of 3 patients with resistant VT were finally included. In all cases, the patients were initially administered amiodarone in the different doses intravenously to stabilize the critical condition, whereas its oral form along with that of propranolol was used as maintenance therapy in the first 2 cases. In the third case, amiodarone was withdrawn because of the risk of development of hyperthyroidism, while oral propranolol was used in the treatment. The assessment in the 16-month follow-up period after discharge did not show presence of non-sustained and sustained VT in all 3 cases. In the ventricular arrhythmia-free group, the total mortality rate within the follow-up period was 11.1 ±â€…7.78 months in the 3 patients. We suggest that maintenance oral therapy of propranolol and amiodarone can significantly decrease the risks of complications in patients with VT after implantation of ventricular assist device in the long term.

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.

Correlation between the AHCPR (Agency For Health Care Policy and Research) risk stratification and angiographic morphology in non-ST-segment elevation acute coronary syndrome.

OBJECTIVES: Risk stratification in acute coronary syndromes is an important diagnostic tool guiding future therapy. We evaluated the correlation between the AHCPR (Agency for Health Care Policy and Research) risk classification and angiographic morphology in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). STUDY DESIGN: A total of 163 patients hospitalized with the diagnosis of NSTE-ACS were prospectively enrolled. All the patients underwent AHCPR risk analysis followed by coronary angiography. Based on the AHCPR system, the patients were classified as low (n=25, mean age 55±10 years), intermediate (n=55, mean age 58±10 years), and high (n=83, mean age 61±11 years) risk groups. RESULTS: The three groups were similar with regard to gender, age, and coronary heart disease risk factors (p>0.05). Comparison of the high-risk group with intermediate+low-risk group with regard to lesion morphology showed significantly higher rates of complex lesions (31.9% vs. 4.0%, p=0.001), total occlusion (23.2% vs. 0%, p=0.001), and intracoronary thrombosis (13% vs. 2%, p=0.02) in the high-risk group. In univariate analysis, high risk was significantly associated with the presence of complex lesion, total occlusion, intracoronary thrombosis, and TIMI flow

Real-life data of major and minor bleeding events with direct oral anticoagulants in the one-year follow-up period: The NOAC-TURK study.

OBJECTIVE: This study aimed to evaluate the safety of direct oral anticoagulants (DOACs) in patients with non-valvular atrial fibrillation (NVAF) during daily clinical practice. METHODS: This was a prospective study conducted between January 01, 2016, and April 01, 2017, in patients aged ≥18 years with a diagnosis of NVAF. We performed the study in 9 clinical centers from different regions of Turkey, and the mean follow-up period was 12+2 months. We investigated major and minor bleeding events of DOAC. RESULTS: A total of 1807 patients with NVAF were enrolled. The mean age of the patients was 73.6±10.2 years, CHA2DS2-VASc score was 3.6±1.4, and HAS-BLED score was 2±1.2. The most frequently prescribed DOAC was dabigatran 110 mg bid in 409 (22.6%) patients. The patients on apixaban 2.5 mg bid were older (p<0.001). Patients on rivaroxaban 15 mg od also had a higher prevalence of chronic renal failure, 46 (16.7%) patients. A total of 205 (11.4%) bleeding events were observed; among these, 34 (1.9%) patients had major bleeding and 171 (9.4%) patients had minor bleeding. The major and minor bleeding events were 2/273 (0.7%) and 30/273 (10.9%) in patients receiving dabigatran 150 mg bid, 13/409 (3%) and 44/409 (10.7%) in patients receiving dabigatran 110 mg bid, 4/385 (1%) and 42/385 (10.9%) in patients receiving rivaroxaban 20 mg od, 8/276 (2.9%) and 27/276 (9.7%) in patients receiving rivaroxaban 15 mg od, 3/308 (0.9%) and 14/308 (4.5%) in patients receiving apixaban 5 mg bid, 4/156 (2.5%) and 14/156 (9%) in patients receiving apixaban 2.5 mg bid, respectively. The total bleeding events were 17 (5.6%) in patients receiving apixaban 5 mg, less than those receiving other DOACs. On multivariate analyses, rivaroxaban 20 mg od (p=0.002), ATRIA and HAS-BLED scores, and peripheral artery disease were independent indicators of bleeding. The most frequent location of major bleeding was the gastrointestinal system (GIS) [17 (0.9%) patients], and the most frequent location of minor bleeding was the gingiva [45 (2.5%) patients]. CONCLUSION: This study showed that similar results as the previous real-life study; however, we had some different results, such as the GIS tract bleeding was more frequent in patients receiving dabigatran 110 mg bid. The major and intracranial bleeding events were similar for different DOACs; and among DOACs, only rivaroxaban 20 mg od was associated with a high risk of bleeding.

Immediate and follow-up results of repeat percutaneous mitral balloon commissurotomy for restenosis after a succesful first procedure.

BACKGROUND: The widespread use of percutaneous mitral commissurotomy (PMC) has led to an increase in restenosis cases. The data regarding follow-up results of repeat PMC are quite limited. The aim of this retrospective analysis is to evaluate the immediate and midterm results of the second PMC, in patients with symptomatic mitral restenosis after a succesful first procedure. METHODS: Twenty patients (95% female, mean age 37 ± 4 years) who have undergone a second PMC, 6.3 ± 2.5 years after a first successful intervention built the study group. All were in sinus rhythm, with a mean Wilkins score of 8.5 ± 1.2. RESULTS: The valve area increased from 1.2 ± 0.2 to 1.9 ± 0.2 cm(2) and mean gradient decreased from 10.5 ± 3.4 to 6.1 ± 1.1 mmHg. There were no complications except for a transient embolic event without sequela (5%) and two cases (10%) of severe mitral regurgitation. The immediate success rate was 90%. The mean follow-up was 70 ± 29 months (36-156 months). The 5-year restenosis and intervention (repeat PMC or valve replacement) rates were 9.1 ± 5.2% and 3.6 ± 3.3%, respectively. The intervention free 5-year survival in good functional capacity (New York Heart Association [NYHA] I-II) was 95.1 ± 5.5% and restenosis and intervention free 5-year survival with good functional capacity was 89.7 ± 6.8%. CONCLUSIONS: Although from a limited number of selected patients, these findings indicate that repeat PMC is a safe and effective method, with follow-up results similar to a first intervention and should be considered as the first therapeutic option in suitable patients.

Effect of acute kidney injury on long-term mortality in patients with ST-segment elevation myocardial infarction complicated by cardiogenic shock who underwent primary percutaneous coronary intervention in a high-volume tertiary center.

OBJECTIVE: Acute kidney injury (AKI) is a reflection of both renal and cardiac reserve in patients with ST-segment elevation myocardial infarction (STEMI), but there is a lack of evidence related to the effect of AKI on long-term mortality in patients with STEMI. This study was an investigation of the prognostic value of AKI for long-term mortality in patients with STEMI complicated by cardiogenic shock (CS) and primary percutaneous coronary intervention (PPCI). METHODS: This retrospective analysis evaluated the long-term prognostic impact of AKI on 492 patients with STEMI complicated by CS who were treated with PPCI. AKI was defined as ≥0.3mg/dL increase in serum creatinine within 48 hours or a ≥50% increase in serum creatinine in 7 days, or a reduction in urine output (documented oliguria of less than 0.5mL/kg per hour >6 hours. Patients were grouped according to the incidence of AKI and long-term mortality was compared. Cox regression analysis was used to determine independent prognostic factors of long-term mortality. RESULTS: In Cox regression analysis, the age- and sex- adjusted hazard ratios (HRs) were higher for all-cause mortality in patients with AKI. [HR: 4.556; 95% confidence interval: (CI) 2.370-8.759]. After adjustment for confounding variables, the relative risk was greater for patients with AKI in comparison with patients without AKI (HR: 2.207; 95% CI: 1.150-4.739). Age (HR: 1.060, 95% CI: 1.027-1.094; p<0.001), left ventricular ejection fraction (HR: 0.952, 95% CI: 0.916-0.989; p=0.012), blood urea nitrogen level (HR: 1.019, 95% CI: 1.005-1.034; p=0.010), and AKI (HR: 2.244, 95% CI: 1.077-4.676; p=0.031) were found to be independent factors to determine long-term mortality. CONCLUSION: The results of this study demonstrated that AKI was an independent prognostic factor for long-term mortality among patients with STEMI complicated by CS and treated with PPCI.

Adherence to guideline-directed medical and device Therapy in outpAtients with heart failure with reduced ejection fraction: The ATA study.

OBJECTIVE: Despite recommendations from heart failure guidelines on the use of pharmacologic and device therapy in patients with heart failure with reduced ejection fraction (HFrEF), important inconsistencies in guideline adherence persist in practice. The aim of this study was to assess adherence to guideline-directed medical and device therapy for the treatment of patients with chronic HFrEF (left ventricular ejection fraction ≤40%). METHODS: The Adherence to guideline-directed medical and device Therapy in outpAtients with HFrEF (ATA) study is a prospective, multicenter, observational study conducted in 24 centers from January 2019 to June 2019. RESULTS: The study included 1462 outpatients (male: 70.1%, mean age: 67±11 years, mean LVEF: 30%±6%) with chronic HFrEF. Renin-angiotensin system (RAS) inhibitors, beta-blockers, mineralocorticoid receptor antagonists (MRAs), and ivabradin were used in 78.2%, 90.2%, 55.4%, and 12.1% of patients, respectively. The proportion of patients receiving target doses of medical treatments was 24.6% for RAS inhibitors, 9.9% for beta-blockers, and 10.5% for MRAs. Among patients who met the criteria for implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy (CRT), only 16.9% of patients received an ICD (167 of 983) and 34% (95 of 279) of patients underwent CRT (95 of 279). CONCLUSION: The ATA study shows that most HFrEF outpatients receive RAS inhibitors and beta-blockers but not MRAs or ivabradin when the medical reasons for nonuse, such as drug intolerance or contraindications, are taken into account. In addition, most eligible patients with HFrEF do not receive target doses of pharmacological treatments or guideline-recommended device therapy.

Effects of aldosterone blockade on left ventricular function and clinical status during acute myocardial infarction.

OBJECTIVE: Heart failure is frequently a serious complication of acute myocardial infarction (AMI). ACE inhibitors, Angiotensin II receptor blockers, beta-blockers and aldosterone receptor blockers have been shown to improve outcomes in this setting. This study aimed to determine the effect of spironolactone on the frequency of clinical heart failure, mortality, rehospitalization and left ventricular functions determined by echocardiography. MATERIAL AND METHODS: A total of 82 patients with STEMI hospitalized within 6-12 h of debut of symptoms were included in the study. The patients were randomly assigned into spironolactone (group A) or placebo (group B) groups after informed consent had been obtained. RESULTS: All patients were followed for 6 months. There were no statistically significant differences between the two groups when demographic criteria were compared. The incidence of post-MI angina pectoris, rhythm and conduction disturbance during hospitalization was significantly higher in Group B than in Group A. Although not statistically significant, the incidence of clinical heart failure was slightly lower in Group A than in Group B (5% versus 11%). Left ventricular end-diastolic volumes were slightly lower in Group A than in Group B, although statistically this was not significant. CONCLUSIONS: In concordance with these findings, the ejection fraction was slightly higher in Group A than in Group B, although this was not statistically significant (47% versus 44%). This trend continued during a 6-month follow-up after randomization. Our findings suggest that early administration of aldosterone blockers provides additional benefits after AMI, reducing the incidence of post-MI angina pectoris and rhythm and conduction disturbances.

Lipoma of the right atrium.

A 66-year-old asymptomatic woman was admitted to our hospital with the diagnosis of a right atrial mass detected on an outside transthoracic echocardiogram and confirmed on transesophageal echocardiography. Physical examination and basal electrocardiogram were normal. Transthoracic echocardiography revealed a 3.8 x 2.5 cm echogenic mass in the right atrium. A multislice CT examination demonstrated a right atrial mass with a fat density ranging from -80 to -110 HU. The patient had a successful surgical excision of the mass, and the diagnosis of lipoma was confirmed on histopathological examination.

The impact of diabetes and coronary artery disease on mortality and morbidity in patients with hypertension.

OBJECTIVES: We evaluated the impact of diabetes mellitus (DM) and/or coronary artery disease (CAD) on cardiovascular endpoints in a cohort of hypertensive patients. STUDY DESIGN: The Vascular Risk Study is a cross-sectional, multicenter, observational study conducted among 5,600 patients from various regions of Turkey. This analysis included 2,664 patients (1,643 women, 1,021 men; mean age 65.3 years; range 55-99 years) whose follow-up data were adequate among a population of 4,506 hypertensive subjects. Cardiovascular primary and secondary endpoints at the end of a five-year follow-up were assessed in patients who had hypertension alone, and in those having DM and/or CAD. Information on the cause of death was obtained from the relatives of the patients by follow-up phone calls. RESULTS: There were 1,171 patients (44%) with isolated hypertension, 631 (23.7%) with DM, 530 (19.9%) with CAD, and 332 (12.5%) with both DM and CAD. The presence of either DM or CAD was associated with significant increases in the incidences of all endpoints. The occurrences of primary and secondary endpoints, cardiovascular death, and all death were similar in hypertensive patients who had DM without CAD and in patients who had CAD without DM. In survival analysis, the incidence of cardiovascular death was lowest (5.7%) in hypertensive patients without DM and CAD, and highest (18.4%) in hypertensive patients with DM and CAD. The cumulative survival rates were similar in hypertensive patients with either DM or CAD alone (p>0.05). CONCLUSION: This study demonstrated that the level of cardiovascular risk associated with DM was equal to the risk associated with CAD in hypertensive patients and that the coexistence of DM and CAD in these patients increases the risk geometrically.

Pericarditis due to an unusual microorganismin an immunocompromised patient.

A 77-year-old man with a past medical history of myelodysplastic syndrome, coronary artery disease, hypertension, and chronic atrial fibrillation presented at the hematology outpatient clinic with progressive shortness of breath, weakness, and chest and back pain. Echocardiography was performed and the patient was diagnosed with severe pericardial effusion near the right ventricle. Pericardial drainage was performed. Erysipelothrix rhusiopathiae was isolated from the pericardial fluid. Complications of respiratory and renal failure developed during follow-up. The clinical and laboratory findings of vegetation on the tricuspid valve, pericardial effusion, and atrial fibrillation with a low heart rate suggested possible pancarditis. A multidisciplinary treatment approach with the cardiology and infectious disease departments was critical to successful management of this case.
