“But doc, my blood pressure is always normal at home.” I wish I had a dollar for every time I have heard that line and I know it is true. When some patients come to see me, their blood pressure is abnormally high (above 130/90). This is known as “white-coat hypertension.” Although it has been thought to be from anxiety about seeing the doctor, even long-established patients who have no conscious anxiety can exhibit elevated blood pressure in the office.
Because blood pressure naturally fluctuates and the office visit is not a “normal” setting, it is important for patients who have high blood pressure (hypertension) to have their own blood pressure cuff at home. Now that devices are automated and easy to use, everyone with hypertension should be monitoring their blood pressure in the comfort of their own home. I advise multiple readings over a week at different times of day. Get a reading when resting and when rushing around. Take your blood pressure after you exercise and after a meal. It is important to keep a log and write it down. Only then can we see patterns and know if the blood pressure is controlled or not.
Blood pressure readings in the doctors office are not necessarily the most accurate. Patients are often rushed trying to get parked and in on time. Medical assistants can use the wrong size cuff or not position the arm correctly. Listening (auscultation) is not very accurate due to human error. It is the multiple readings over time that give a more accurate picture of blood pressure control.
High blood pressure in the office can be true hypertension or it can be white-coat hypertension that is usually controlled at home. If a patient is on blood pressure medication and has controlled blood pressure at home, I will not add more medication just because they are elevated in the office. If a patient has not been diagnosed with hypertension and his or her blood pressure is elevated in the office, he or she is advised to get their own blood pressure cuff for at home and return with readings for us to review. This way we can minimize unnecessary and expensive medication and make sure we are protecting the patient as well.

Genome-wide profiling is increasingly being marketed towards consumers to assess their risk of developing certain diseases. However, there has been little research into the psychological effects of these tests.
Researchers from Scripps Translational Science Institute have now looked into these effects in a large group of patients. They followed 2,037 participants who took the Navigenics Health Compass, a test that assesses the risk for about 20 common diseases, for a period of three months.
Taking the test did not increase anxiety symptoms, dietary fat intake, or exercise behavior. There was some test-related distress correlated with the average estimated lifetime risk of getting the diseases tested for, but at the same time 90.3 percent of all subjects had no test-related distress at all. The use of screening tests did not change among the group and notably health effects of the test were not studied.
In conclusion, personal genetic testing does not seem to generate a lot of distress, although the study was clearly limited by a high dropout percentage of 44 percent and the self-selection of participants who opted to do the test.

If a website touted misleading healthcare information, you’d hope the government would do something about it. But what do you do when the government is the one feeding the public bad information?
Last week the Obama administration launched the new Healthcare.gov. It’s mostly an online insurance shopping website. It’s very much a federal government version of sites like eHealthInsurance.com or Massachsetts’ HealthConnector site, which have been around for years.
So when HHS Secretary Kathleen Sebelius, in announcing the new site, claims it gives consumers “unprecedented transparency” into the healthcare marketplace, you should wonder what she means. But that’s not the big problem with this site. Read more »
