[The intracardiac laser irradiation of the blood in correcting left ventricular dysfunction in progressive...

Area of Science:

• Cardiology
• Medical Physics
• Laser Therapy

Background:

• Progressive angina pectoris significantly impairs left ventricular (LV) function.
• Conventional treatments for angina have limitations in improving cardiac hemodynamics.
• Intracardiac laser irradiation is an emerging therapeutic modality.

Purpose of the Study:

• To evaluate the effect of low-intensity Helium-Neon laser irradiation of blood on the pumping function of the left ventricle in patients with progressive angina pectoris.
• To compare the efficacy of laser hemotherapy combined with medication against conventional medical therapy alone.

Main Methods:

• A study involving 73 patients with progressive angina pectoris.
• 47 patients received laser hemotherapy concurrently with medication.
• 26 patients received standard medical therapy (nitrates, calcium antagonists, analgesics).

Main Results:

• Laser hemotherapy demonstrated a more satisfactory clinical effect compared to the control group.
• Intracardiac laser irradiation improved hemodynamic characteristics by reducing LV volumes and increasing LV ejection fraction.
• The beneficial effects are attributed to improved LV regional contractility and anti-ischemic properties.

Conclusions:

• Low-intensity Helium-Neon laser hemotherapy is effective in improving left ventricular function and intracardiac hemodynamics in patients with progressive angina pectoris.
• Laser therapy offers a promising adjunctive treatment for angina by stabilizing LV contractility and exerting an anti-ischemic effect.
• This therapeutic approach provides a superior clinical outcome compared to conventional medical management alone.
