Insights
A novel Diastolic Timed Vibrator (DTV) uses mechanical vibrations for pre-hospital treatment of acute coronary ischemia. This non-invasive method aids reperfusion and clot dissolution, potentially improving patient survival rates.
Area of Science:
- Biomedical Engineering
- Cardiovascular Medicine
- Medical Devices
Background:
- Acute coronary ischemia necessitates rapid intervention to improve patient survival.
- Current treatments, pharmacological and interventional, have limitations in speed and accessibility.
- There is a need for effective pre-hospital treatments for acute coronary ischemia.
Purpose of the Study:
- To introduce a novel pre-hospital treatment for acute coronary ischemia using mechanical vibrations.
- To describe the Diastolic Timed Vibrator (DTV) device and its operational principles.
- To demonstrate the feasibility of the DTV for early intervention in acute coronary ischemia.
Main Methods:
- Development of the Diastolic Timed Vibrator (DTV) device.
- Implementation of a custom electrocardiogram (ECG) processing algorithm for precise timing.
- Application of low-frequency mechanical vibrations to the chest during cardiac diastole.
Main Results:
- Experimental results confirm the functionality of the DTV device.
- The DTV system integrates ECG processing, vibration generation, and active braking.
- The proposed method shows potential for safe application by minimally trained personnel.
Conclusions:
- The Diastolic Timed Vibrator (DTV) presents a promising non-invasive approach for pre-hospital acute coronary ischemia management.
- Mechanical vibrations enhance blood mixing, facilitate drug delivery, aid clot dissolution, and act as vasodilators.
- Further in-vivo testing is warranted to validate the clinical efficacy of the DTV for acute coronary ischemia treatment.
Abstract:
The speed of intervention is one of the major factors in increasing the survival rate of patients suffering from acute coronary ischemia. The two principal techniques currently in use: pharmacological and interventional, can be employed to re-canalize coronary arteries, but the former is slow acting and often leads to incomplete reperfusion, while the latter requires specialized personnel in a hospital with a cardiac catheterization laboratory. In this paper, we introduce a novel method intended for pre-hospitalization treatment of patients with acute coronary ischemia that can be safely applied by a minimally trained individual prior to or during patient transportation to hospital. It consists in applying low frequency mechanical vibrations to the left intercostal space of patient's chest during diastole of the heart cycle, to induce vibrations of the heart and thus of the coronary arteries. Mechanical vibrations stimulate mixing of blood which improves drug delivery to the occlusion site, applies mechanical force on the clot leading to its faster dissolution and finally acts as a strong vasodilator in case of spasms. We introduce the principle of operation and the architecture of the Diastolic Timed Vibrator (DTV), including a custom ECG processing algorithm, vibration pattern generator and active braking methods. Experimental results demonstrate the functionality of the DTV device and pave way for in-vivo tests necessary for clinical confirmation of the proposed method.
