Researchers at the University of California at San Francisco have found that aggressive treatment for high blood pressure can prevent left ventricular conduction problems. The research was published in the journal JAMA Cardiology.
Cardiac conduction disorders can often lead to fatal complications, including complete heart block or heart failure. Treatment may include implanting a pacemaker. At the same time, effective prevention of heart block has not yet been developed.
In the new study, researchers randomly assigned people with hypertension to receive more or less aggressive pressure-lowering therapy—that is, to keep their systolic blood pressure below 120 or 140 mmHg. Art.
Using the EKG, the researchers found that intense pressure control was associated with a lower risk of left ventricular conduction disturbances. This indicates that left ventricular conduction disturbance can be prevented.
The scientists noted that they have not studied the role of antihypertensive drugs, so more research may be needed on the relationship between certain drugs and the frequency of conduction disorders.
