Abstract

Abstract: Objective: To explore and study the clinical usefulness of continuous dynamic recording of left cardiac function changes forevaluation the improvement in patients with chronic disease after 3 months of intensive control of individualized precision exercise overall manage program. Methods: From 2018 to 2021, 21 patients with chronic cardiovascular and cerebrovascular metabolic diseases mainly controlled by our team were selected to complete the cardiopulmonary exercise test (CPET) and Non-invasive synchronous cardiac function detector (N-ISCFD), electrocardiogram, radial pulse wave, jugular pulse wave and cardiogram data were continuously recorded for 50s.According to the titration results under CPET and continuous functional parameters monitoring, a holistic plan with individualized moderate exercise intensity as the core was developed for 3 months of intensive management, and then N-ISCFD data collection was repeatedafter signing the informed consent. All N-ISCFD data were analyzed in the 50s according to the optimal report mode of Fuwai Hospital and 52 cardiac functional indexes were calculated. The data before and after the enhanced control were compared and the paired T-test was used to statistically analyze the changes of groups. Results: Twenty-one patients with chronic diseases (16 male and 5 female) were (54.05±12.77,29~75) years, BMI (25.53±4.04,16.62~31.7) kg/m².Comparison with baseline,the whole group analysis: ①The body weight, BMI, systolic blood pressure and diastolic blood pressure of patients were significantly decreased(P＜0.01).②CPET Peak VO₂ was (64.93±24.22, 26.96~103.48) %Pred before enhanced control, and (85.22±30.31, 43.95~140.48) %Pred after enhanced control, and increased (35.09±27.87, 0.12~129.35) % after enhanced control compared with before enhanced control. The AT, Peak VO₂/HR, Peak Work Rate, OUEP, FVC, FEV₁, FEV3/FVC% and MVV were significantly increased (P＜0.01) and the Lowest VE/VCO₂ and VE/VCO₂ Slope were significantly decreased(P＜0.01).③Core indicators of left heart function:Ejection fraction was significantly increased from (0.60±0.12,0.40~0.88) to(0.66±0.09, 0.53~0.87)(P＜ 0.01), by (12.39±14.90,-12.32~41.11)%. The total peripheral resistance was significantly decreased from (1579.52±425.45,779.46~2409.61) G/(cm⁴·s),to(1340.44±261.49,756.05~1827.01) G/(cm⁴·s)(P＜0.01), by (12.00±17.27,37.79~28.61) %.The left stroke index, cardiac total power, ejective pressure and left ventricular end diastolic volumewere significantly improved (P＜0.05).The change analysis of each indicator for each patient is shown in the individualized analysis section of this study. Conclusion: Use CPET and continuous functional monitoring we can safely and effectively develop the overall program of individualized exercise in patients with chronic diseases. Long-term intensive management and control can safely and effectively significantly improve the cardiovascular function of patients. Continuous dynamic recording of changes in left and right cardiac functional parameters can be a simple way to supplement CPET to evaluate cardiovascular function.
