Right ventricular volume determination in isolated human hearts

1986

For right ventricular volume determination a new method was developed that took into account right ventricular imaging by apical two-dimensional echocardiography in the four- and two-chamber views. Right ventricular volume was calculated by subtraction of the partial volume of the left ventricle and interventricular septum from the total heart volume of the right and left ventricles including the interventricular septum. Accuracy of the subtraction method was evaluated in isolated human hearts by two-dimensional echocardiography and radiography. Regression analysis indicated that for both the echocardiographic and radiologic procedures, the subtraction method gave the best correlation with …

Interventional and surgical modalities of treatment for pulmonary arterial hypertension

2004

AbstractBeyond medical therapy, different interventional and surgical approaches exist for treatment of pulmonary arterial hypertension (PAH). Atrial septostomy has been applied in patients with lack of response to medical therapy in the absence of other surgical treatment options. With growing experience, procedure-related death rates have been reduced to 5.4%, and the most suitable patient group has been identified among patients with a mean right atrial pressure between 10 and 20 mm Hg. Pulmonary endarterectomy is the accepted form of treatment for patients with chronic thromboembolic pulmonary hypertension. Establishing the diagnosis and the classification of the type of lesions by pulm…

Predictors of individual adaptation to high-volume or high-intensity endurance training in recreational endurance runners

2015

The aim of this study was to investigate factors that can predict individual adaptation to high-volume or high-intensity endurance training. After the first 8-week preparation period, 37 recreational endurance runners were matched into the high-volume training group (HVT) and high-intensity training group (HIT). During the next 8-week training period, HVT increased their running training volume and HIT increased training intensity. Endurance performance characteristics, heart rate variability (HRV), and serum hormone concentrations were measured before and after the training periods. While HIT improved peak treadmill running speed (RSpeak ) 3.1 ± 2.8% (P < 0.001), no significant changes occ…

Letter by Sacha and Feusette Regarding Article, “Dynamic Edematous Response of the Human Heart to Myocardial Infarction: Implications for Assessing M…

2018

We have read with a great interest the article by Fernandez-Jimenez et al presenting a bimodal edematous reaction of reperfused myocardium after ST-segment elevation myocardial infarction (STEMI).1 According to the study, the initial edema emerges early and disappears by 24 hours; however, the second edema appears between days 4 and 7 after reperfusion. The authors conclude that the assessment of …

The Heart in Fabry Disease – from Pathogenesis to Enzyme Replacement Therapy

2010

The cardiovascular involvement in Fabry disease is progressive, and accounts for one of the major reasons for abbreviated life expectancy and increased morbidity. The majority of patients develop signs and symptoms, related to heart failure and arrhythmias. Hypertrophic cardiomyopathy, in later stages combined with myocardial fibrosis, is one of the leading features. Both genders are affected, and females develop severe cardiac Fabry disease approximately 10–15 years later in life than male patients. Diastolic dysfunction and reduced longitudinal mid-wall related systolic function are the mechanical consequences of the myocardial and epithelial changes related to accumulation of the storage…

Discordance in prognostic ability between physician assessed NYHA classification and self-reported health status in patients with acute heart failure

2021

Abstract Background Especially in patients with acute heart failure (AHF) the NYHA classification remains of uncertain representation of patients' actual health state. Alternatively, patient's subjective well-being, in terms of health-related quality of life (HRQL), showed to have an excellent prognostic ability in out clinic patients with chronic heart failure. Objectives It is unknown whether HRQL instruments can assess a more reliable prognostication in patients hospitalized due to AHF than the NYHA classification. Methods Goal Directed Afterload Reduction in Acute Congestive Cardiac Decompensation Study (GALACTIC) was a multicenter, randomized, open-label blinded-end-point trial that em…

P4550Growth differentiation factor 15 as an integrative biomarker of heart failure in patients with acute myocardial infarction

2019

Abstract Background Growth differentiation factor 15 (GDF15), a stress-responsive cytokine member of the transforming growth factor-β family, is an emerging biomarker in cardiovascular (CV) diseases. GDF15 is weakly expressed in normal condition but increased in pathological situations such as inflammation, oxidative stress, and left ventricular remodeling. Recent data suggest GDF15 as a marker in heart failure (HF). Purpose We aimed to identify the determinants of GDF15 circulating levels in patients admitted for an acute myocardial infarction (AMI). Methods In our prospective study, all consecutive patients admitted from June 2016 to February 2018 for type 1 AMI in the Coronary Care unit …
