Heart problems. Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack and heart failure. These conditions may cause low blood pressure because they prevent your body from being able to circulate enough blood. 1  Endocrine problems.
Causes of low blood pressure: Heart disease. 1  Weakened heart muscle can cause the heart to fail and reduce the amount of blood it pumps. 2  One common cause of weakened heart muscle is the death of a large portion of the heart's muscle due to a single, large heart attack or repeated smaller heart attacks. The resting heart rate for a healthy adult is between 60 and 100 beats/minute. 2  Bradycardia (resting heart rates slower than 60 beats/minute) does not always cause low blood pressure. 3  In fact, some highly trained athletes can have resting heart rates in the 40s and 50s (beats per minute) without any symptoms.
