BACKGROUND: Left ventricular (LV) function and the dimensions of aortic valves from normally functioning bicuspid aortic valve (BAV) patients were compared with those of healthy control patients. A comparison between patients with antero-posterior BAV (BAV-AP) or right-left BAV (BAV-RL) was also performed, and the determinants of aortopathy and LV function were investigated. METHODS: Sixty-eight patients with aortic velocities <2 m/s and trivial or mild aortic regurgitation were included in the study...

Objective: To investigate the association between management of Internal Medical Units (IMUs) with outcomes (mortality and length of stay) within the Spanish National Health Service. Design: Data on management were obtained from a descriptive transversal study performed among IMUs of the acute hospitals. Outcome indicators were taken from an administrative database of all hospital discharges from the IMUs. Setting: Spanish National Health Service...

PURPOSE: Differences in the utility of routine angiographic follow-up (RAF) and clinical follow-up (CF) after percutaneous coronary intervention (PCI) in acute myocardial infarction (AMI) are not well understood. The present study aimed to compare the 3-year clinical outcomes of RAF and CF in AMI patients who underwent PCI with drug-eluting stents (DES). MATERIALS AND METHODS: A total of 774 consecutive AMI patients who underwent PCI with DES were enrolled. RAF was performed at 6 to 9 months after index PCI (n=425)...

BACKGROUND Hypothyroid has several effects on the cardiovascular system. Global myocardial performance index (MPI) is used in assessment of both left ventricular (LV) systolic and diastolic function. We compared MPI in hypothyroidism patients vs. normal control subjects. MATERIAL AND METHODS Eighty-two hypothyroid patients were divided into 2 groups: a subclinical hypothyroid (SH) group (n=50), and an overt hypothyroid (OH) group (n=32). The healthy control group (CG) constituted of 37 patients. TSH, FT3, and FT4, anti-TPO, anti-TG, insulin, lipid values, and fasting glucose levels were studied...

AIM: The aim of this study was to investigate if the myocardial performance index (MPI) is altered in fetuses in women with gestational impaired glucose tolerance (GIGT), controlled on diet and whether this parameter is also predictive of adverse outcome in this group, as in poorly controlled gestational diabetes. METHOD: In a prospective cross-sectional study thirty two women with gestational impaired glucose tolerance on diet in the 3(rd) trimester were recruited and matched with 32 women with normal pregnancies (control group)...

BACKGROUND: Scarce data comparing real-world outcomes between apixaban and vitamin K antagonist (VKA) users with nonvalvular atrial fibrillation (NVAF) are available. We sought to assess the effectiveness and safety of newly-initiated apixaban vs. VKA in German NVAF patients. MATERIALS AND METHODS: We performed a retrospective analysis in German outpatients using IMS Disease Analyzer data. Adults newly-initiated on apixaban or a VKA from January 2013 to March 2015 with a diagnosis of NVAF on the day of the first qualifying oral anticoagulant (OAC) prescription (index date) or any time during one year prior, and at least one year of follow-up were included...

BACKGROUND: Ischemia, in the absence of obstructive coronary artery disease, is prevalent in women, and associated with increased risk for major cardiovascular events. Coronary microvascular dysfunction is prevalent in these patients, and associated with impaired diastolic function. Despite our general understanding, however, optimal treatment of this cohort remains elusive. METHODS: To address this knowledge gap, we performed an open-label treatment trial to assess whether phosphodiesterase type 5 inhibition improves coronary microvascular perfusion and diastolic function in women with signs and symptoms of ischemia but no evidence of obstructive coronary artery disease...

AIM: To study of the impact of shock-wave therapy (SWT) on the functional status of patients with coronary heart disease (CHD). SUBJECTS AND METHODS: Thirty-four CHD patients (including 33 men) with left ventricular (LV) asynergic segments, as evidenced by echocardiography (EchoCG), were examined. Their mean age was 60.1±1.76 years. All the patients received a SWT cycle according to the standard scheme. The patient examination protocol involved EchoCG, dobutamine EchoCG, treadmill exercise EchoCG, and tissue Doppler EchoCG, which were performed at baseline, immediately and one month after the end of a SWT cycle...

OBJECTIVES: In mothers with pre-gestational or gestational diabetes, abnormal arterial stiffness (stiffer arteries) has been reported. The impact of abnormal maternal arterial stiffness on fetal placental and cardiovascular physiology is unknown. The purpose of the study was to determine the impact of maternal diabetes on maternal arterial stiffness and the association with fetal cardiovascular physiology as measured by fetal echocardiography. METHODS: Between December 2013 and January 2017 we conducted a prospective study on diabetic (otherwise healthy) and non-diabetic, healthy pregnant mothers (at 20-28 gestational weeks and 18-40 years of age) who had a normal fetal cardiac echocardiogram and obstetric ultrasound...

OBJECTIVES: To evaluate the reproducibility of the fetal right myocardial performance index determined by simultaneous recording of inflow and outflow using a dual gate pulsed-wave Doppler (DD). METHODS: This was a prospective study of 39 normal singleton fetuses. Two experienced operators each measured the right myocardial performance index in three ways, twice: (1) separate recording of the inflow and outflow using single-gate pulsed-wave Doppler (PD), (2) simultaneous recordings of the inflow and outflow using tissue Doppler (TD), and (3) simultaneous recordings of the inflow and outflow using DD...

BACKGROUND: Hyperglycaemia-induced oxidative damage is a well-established factor implicated in the development of diabetic cardiomyopathy (DCM) in diabetic individuals. Some of the well-known characteristics of DCM include increased myocardial left ventricular wall thickness and remodelling that result in reduced cardiac efficiency. To prevent this, an increasing number of pharmacological compounds such as N-acetyl cysteine (NAC) are explored for their antioxidant properties. A few studies have shown that NAC can ameliorate hyperglycaemia-induced oxidative damage within the heart...

Estimation of right ventricular (RV) performance still remains technically challenging due to its anatomical and functional distinctiveness. The current guidelines for the echocardiographic quantification of RV function recommend using multiple indices to describe the RV in a thorough and comprehensive manner, such as RV index of myocardial performance, tricuspid annular plane systolic excursion, fractional area change, Doppler tissue imaging-derived tricuspid lateral annular systolic velocity (S'-wave), three-dimensional RV ejection fraction (3D RVEF), longitudinal strain (RVLS)/strain rate by speckle-tracking echocardiography (STE)...

BACKGROUND: Speckle tracking echocardiography (STE) is an echocardiography modality that is able to measure left ventricular (LV) characteristics, including rotation, strain and strain rate. Strain measures myocardial fibre contraction and relaxation. This study aims to assess the effect of renal sympathetic denervation (RDN) on functional myocardial parameters, including STE, and to identify potential differences between responders and non-responders. METHODS: The study population consisted of 31 consecutive patients undergoing RDN in the context of treatment for resistant hypertension...

Percutaneous coronary intervention (PCI) continues to evolve with shifting patient demographics, treatments, and outcomes. We sought to document the specific changes observed over a 9-year period in a contemporary Australian PCI cohort. The Melbourne Interventional Group is an established multicenter PCI registry in Melbourne, Australia. Data were collected prospectively with 30-day and 12-month follow-ups. Demographic, procedural, and outcome data for all consecutive patients were analyzed with a year-to-year comparison from 2005 to 2013...
