HYPOTENSION

This pilot study tests whether a non-invasive brain stimulation technique called temporal interference stimulation can safely help regulate blood pressure. Researchers will enroll 25 adults with either mild untreated hypertension or hard-to-control high blood pressure. Participan…

This study tests whether midodrine, a drug that raises blood pressure, can help people with heart failure and low blood pressure tolerate the standard heart medications that save lives. About 56 adults with weak hearts and low blood pressure will be randomly assigned to get midod…

This study tests whether applying mild electrical stimulation to specific acupoints (Neiguan and Jian Shi) for 30 minutes before anesthesia can help prevent low blood pressure in adults over 65 undergoing surgery. Researchers will compare high-frequency versus low-frequency stimu…

This study tests a smartphone app called One.Dr to see if it can reduce the drop in blood pressure that happens when people with orthostatic hypotension stand up. About 86 adults who get dizzy when standing will be randomly assigned to use the real app or a sham version for 6 wee…

This study will check if frailty—a state of weakness common in older adults—makes blood pressure drop more after anesthesia. About 80 people aged 65 and older having surgery will be assessed using a simple frailty scale. The goal is to help doctors better predict and prevent comp…

This study looks at whether measuring the size of a neck vein with ultrasound can predict low blood pressure after anesthesia. Researchers will check 42 adults having gallbladder surgery. The goal is to find a simple, non-invasive way to identify patients at higher risk.
