Study Overview

Brief Summary

The study aimed to highlight the effect of high-intensity interval training (HIIT) on cardiac fibrosis in cardiac patients. From 2009-2018, cardiac patients with measurements of VO2peak, b-type natriuretic peptide, quality of life questionnaire, cardiovascular magnetic resonance imaging with late gadolinium enhancement (CMR-LGE), and preserved serum before and after 36 times of HIIT were enrolled. The human cardiac fibroblast (CF) isolated from human adult ventricle is treated with sera before and after HIIT. Measurements of cell migration as well as cell proliferation and global cell protein profiles before and after HIIT will be performed.

Detailed Description

From January 1, 2009 to December 31, 2018, cardiac patients with stable clinical status for greater than 4 weeks have completed 36 times of HIIT. Subjects with clinical assessments (listed below) before and after HIIT will be included.

*Baseline information, including age, gender, body mass index, duration disease duration, co-morbidities and medication history were reviewed. Subjects with echocardiographic examination, short form-36 health survey (SF-36) for qualities of life, graded cardiopulmonary exercise test (CPET), cardiac magnetic resonance imaging with late gadolinium enhancement (CMR-LGE), blood chemistry tests (hematocrit, brain natriuretic peptide, high-sensitivity C-reactive protein, creatinine), and preserved sera before and after HIIT.*

Cell behaviors Human cardiac fibroblast (CF) isolated from human adult ventricle (HCF-av cell, ScienCell Research Laboratories, Carlsbad, CA, USA) are cultured in medium containing 10 % FBS, 1% fibroblast growth supplement, and 1% penicillin/streptomycin. Cells (1x10^5) were seeded in dishes of 10-cm diameter and were cultured in the above medium overnight. We used 10% of the patient serum in substitution for the 10% fetal bovine serum (FBS) to treat human cardiac fibroblast (CF) isolated from human adult ventricle (HCF-av cell, ScienCell Research Laboratories, Carlsbad, CA, USA), and serum effects on CF were evaluated.

Cell Culture Human cardiac fibroblasts (CFs) isolated from human adult ventricle (HCF-av cell, ScienCell Research Laboratories, Carlsbad, CA, USA) were cultured in medium containing 10 % FBS, 1% fibroblast growth supplement, and 1% penicillin/streptomycin. Cells (1x10^5) were seeded in dishes of 10-cm diameter and were cultured in the above medium overnight.

Cell migration assay The cell migration speed in the serum obtained from cardiac patients pre- and post-HIIT was determined as described previously. In brief, HCF-av cells of 3000 were plated on each 3.5-cm Petri dishes with polyacrylamide substrates and were harvest in media containing 10% of cardiac patient sera before and after HIIT. Phase contrast images were recorded using a cooled charge-coupled device camera (Photometrics, Tucson, AZ), attached to an Eclipse Ti-E inverted microscope system (Nikon Instruments Inc., Melville, NY) equipped with a 20X, numerical aperture 0.75 Achromat phase objective lens and a INU series stage top incubator (Tokai HIT Co., Ltd., Shizuoka-ken, Japan). The position of the cell was determined every 10 min for a period of 120-180 mins, based on the center of the nucleus. Migration speed was calculated based on the persistent random walk equation.
