Left atrial end-systolic volume, peak early diastolic mitral annular velocity, and E/A ratio were reduced by approximately 18%, 15%, and 31% after exercise across groups, while the T2D group had a 265% greater rate of supraventricular extrasystoles per hour than controls.

Why the study?

This study evaluated acute cardiac stress following a high-intensity interval training session in patients with type 2 diabetes compared to healthy controls.

Does a single session of high-intensity interval training acutely impair cardiac function differently in patients with type 2 diabetes compared to healthy controls?

Population

Patients with type 2 diabetes and healthy controls

Comparison

Patients with type 2 diabetes vs healthy controls undergoing high-intensity interval training

Design

Pilot study

Follow-up

24 h after the exercise

Overview

HIIT may transiently impair LV diastolic function similarly in T2D and controls; pilot data leave open differential RV effects and need for larger trials.

Structured PICO

Does a single session of high-intensity interval training acutely impair cardiac function differently in patients with type 2 diabetes compared to healthy controls?

P
Population
Patients with type 2 diabetes (T2D) and healthy controls
I
Intervention
High-intensity interval training session (4 × 4-min intervals at 90-95% of maximal heart rate, followed by a ramp protocol to peak oxygen uptake)
C
Comparator
Healthy controls undergoing the same exercise protocol
O
Outcome
Acute changes in echocardiographic parameters 30 min after exercise and Holter electrocardiography rhythms 24 h before, during, and 24 h after exercisesurrogate

A single session of high-intensity interval training acutely impairs left ventricular diastolic function in both T2D patients and healthy controls, with T2D patients additionally showing impaired right ventricular function and increased supraventricular ectopy.
