High Blood Pressure is a subject about which volumes are written. It’s such a common problem millions of Americans and people worldwide are interested in the latest information about it. They want to know what’s available to help them. What BP level they should try to achieve? Is there another drug with fewer adverse effects I can take that will work as well? Should I worry about a heart attack, kidney failure, or stroke?
Professional organizations everywhere are continually publishing new sets of guidelines on various subjects for physicians and patients to mull over. These organizations keep patients informed but ultimately leave many questions…. What’s the latest recommendation from the American Heart Association? What’s the latest from the Joint National Commission (JNC)? What do the cardiologists say?
Family Physicians are deluged with guidelines on some subject from nearly every specialty society in existence. That’s because were the “catch-all” specialty. We see problems of all types, we diagnose problems of all types, and we treat anything. There is very little of which the family doctor isn’t expected to have a broad general knowledge. High Blood Pressure is one of the major items. High BP guidelines usually contain general recommendations, but optional guidelines for special situations exist that have their own recommendations.
General recommendations fall into a “usual care treatment” group and are not as restrictive or as aggressive in their BP target levels as are patients in the “intensive treatment” group. These patients have serious co-morbidities that make lower target levels necessary. Thus treatment guidelines are either “usual” or “intensive.” Each group has different target levels.
Specialist groups, like the American Heart Association, or the American College of Cardiology have an inclination to favor more intensive BP targets. In other words, they are going to recommend the lowest BP a person can tolerate as their normal target. Whereas the American Academy of Family Physicians (AAFP) sets their target at 140/90, the American Heart Association (AHA) and the American College of Cardiology (ACC) use 130/80.
They have different target levels because they are aimed at different populations of patients. The “intensive group” uses 121 mmHg as their optimum level, and the “usual care group” uses 136 mmHg. The more co-morbidities a patient has and the more problematic they are, the more likely they are to require intensive treatment. The intensive group is less likely to develop heart failure, but the two groups don’t differ in the incidence of heart attack, coronary disease, or stroke.
The intensive treatment group had more episodes of hypotension (low blood pressure) because when the BP is treated aggressively, patients can be over medicated and their baseline BP get too low. There is a tendency for medication to over-react and force the BP to be abnormally low, so much so that the patient becomes weak, lightheaded, dizzy, or near to passing out. When that happens, the BP med dosage should be reduced. The intensive treatment group is also more likely to develop electrolyte abnormalities, acute kidney injury, or kidney failure.
In one study, the tight control group had a mean systolic BP of 118 mmHg while the usual care patients averaged 135 mmHg. “These results have led to calls from specialists to use 130/80 mmHg as the target for all patients.
My wife has had a problem with intensive BP treatment because it put her BP’s in the 92/56 area. Her low BP’s were accompanied by extreme weakness, lightheadedness, and dizziness. She couldn’t stand for more than a few seconds. After her meds were changed, her BP was kept in the 140/80-85 range, instead. When a person doesn’t tolerate BP in the 100/65 range, less medication is advised. These folks need to use a higher target BP of 140/80-85. They are still getting the benefits, but without all the orthostatic symptoms. Some folks just can’t tolerate a BP of 110/70, and they are better off to have a target BP of 138/84 or even higher. Lowering the BP too much definitely increases the risk of adverse kidney effects. Hypotension is just as much a concern as is HBP!
“The decision to pursue a more intensive BP target should not be routine and, at best, should be a shared decision balancing benefits and harms. To avoid over treatment, it is of paramount importance that patients who choose a target BP of less than 130/80 mmHg always have their BP measured seated in a quiet room,” using the right cuff size, their arm bare, and take the average of 3 readings.
