Research summary
The study aims to find out whether patients diagnosed with minor stroke/TIA(mini strokes) have significant differences in blood pressure between outpatient clinic setting and home setting. Raised Blood pressure is an important risk factor for strokes. Blood pressure used to be measured only when patients attend the clinic. Now, it is possible to measure blood pressure outside the hospital/clinic setting using ambulatory blood pressure device as well as by home blood pressure monitors. These technologies have enabled us to identify two new categories of raised blood pressure(BP) – masked hypertension and white coat hypertension. In masked hypertension, patients have normal BP in hospital setting while BP checked at home reveals raised BP. In white coat hypertension, it is exactly opposite. These conditions can be diagnosed either by 24 hour blood pressure monitoring or by doing a set of BP readings done at home. 24 hour BP monitoring measures blood pressure intermittently over a 24 hour period. Home BP monitors measure serial BP readings over a period of 7 days at home. This study is carried out to determine how common is to have two categories of raised blood pressure(BP) – masked hypertension and white coat hypertension in patients with definite diagnosis of minor stroke/TIA .
