Effect of Vascular Photobiomodulation on Cardiovascular Parameters of Treated Hypertensive Patients: A Randomized and Controlled Clinical Trial
This double-blind, randomized, sham-controlled clinical trial aims to evaluate the effects of vascular photobiomodulation on blood pressure and vascular function in hypertensive patients treated with losartan. A total of 80 patients using losartan (100 mg/day for at least two months) will be recruited and followed for 4 weeks. Participants will be randomly allocated to either an active photobiomodulation group or a sham control group.
Inclusion: Be taking losartan at a dose of 100 mg/day, either as monotherapy or in combination with other antihypertensive medications, administered in two divided doses, for a minimum of 2 months and a maximum of 24 months; Present systolic blood pressure is less than or equal to 140 mmHg and diastolic less than or equal to 90 mmHg; Not having used any other antihypertensive medication in the last 2 months; Age between 18 and 65 years; If female, not pregnant; No cutaneous/subcutaneous lesions on both arms; No musculoskeletal, rheumatic, cardiovascular, metabolic, neurological, oncological, immunological, hematological, psychiatric or cognitive diagnoses and that may be worsened by the intervention or prevent the correct application of FBM vascular.
