Eighteen hypertensive patients (13 males, 5 females; age 48 +/- 13; diastolic blood pressure greater than 95 mmHg), either previously untreated or who had been off treatment for more than 3 months, underwent M-mode echocardiography before (DO) and after (D90) 3 months of nicardipine therapy (60-90 mg/day). All echocardiograms were read blind, and left ventricular mass (LVM) was calculated (Devereaux's formula). Blood pressure was significantly reduced after 3 months from 167 +/- 15/102 +/- 8 mmHg on DO to 152 +/- 16/92 +/- mmHg on D90 (p less than 0.001). The reduction in LVM was not significant: 266 +/- 95 g on DO, 247 +/- 78 g on D90. There was a trend to a higher (although nonsignificant) LVM reduction in patients with left ventricular hypertrophy at entry (-11%, n = 11) than in patients without left ventricular hypertrophy (-2%), n = 7).

Feasibility and preliminary efficacy of a physical activity intervention in adults with lymphoma undergoing treatment.
Pilot Feasibility Stud

Department of Internal Medicine - Cardiology, Virginia Commonwealth University, West Hospital 8th Floor, North Wing, Richmond, VA, 23298, USA.
Background: To determine the feasibility, acceptability, and preliminary efficacy of a 6-month tailored non-linear progressive physical activity intervention (PAI) for lymphoma patients undergoing chemotherapy.
Methods: Patients newly diagnosed with lymphoma (non-Hodgkin (NHL) or Hodgkin (HL)) were randomized into the PAI or healthy living intervention (HLI) control (2:1). Feasibility was assessed by examining accrual, adherence, and retention rates.
Aortic valve repair with sinus plication for a regurgitant bicuspid aortic valve: a case report.

Background: Repair of the regurgitant bicuspid aortic valve is an attractive alternative to valve replacement. Although good long-term outcomes have been reported, postoperative aortic stenosis remains a major late cause of repair failure in bicuspid aortic valves. Sinus plication is effective for creating a more symmetrical commissural angle, leading to a decrease in the mean transvalvular pressure gradient.

Purpose: Treatment of pediatric cancers with doxorubicin is a common and predictable cause of cardiomyopathy. Early diagnosis of treatment-induced cardiotoxicity and intervention are major determinants for the prevention of advanced disease. The onset of cardiomyopathies is often accompanied by profound changes in lipid metabolism, including an enhanced uptake of short-chain fatty acids (SCFA).

Doxorubicin (DOX) is an important drug used in the treatment of many malignancies. Unfortunately DOX causes various side effects, with cardiotoxicity being the most characteristic. Risk factors for DOX induced cardiotoxicity (DIC) include cumulative dose of DOX, preexisting cardiovascular diseases, dyslipidemia, diabetes, smoking, along with the use of other cardiotoxic agents.

Objective: To explore the molecular mechanism of Shenmai Injection (SMI) against doxorubicin (DOX) induced cardiomyocyte apoptosis.
Methods: A total of 40 specific pathogen-free (SPF) male Sprague Dawley (SD) male rats were divided into 5 groups based on the random number table, including the control group, the model group, miR-30a agomir group, SMI low-dose (SMI-L) group, and SMI high-dose (SMI-H) group, with 8 rats in each group. Except for the control group, the rats were injected weekly with DOX (2 mg/kg) in the tail vein for 4 weeks to induce myocardial injury, and were given different regimens of continuous intervention for 2 weeks.
