Antihypertensive drugs used to treat predominantly healthy adults aged 18 to 59 years with mild to moderate primary hypertension have a small absolute effect to reduce cardiovascular mortality and morbidity primarily due to reduction in cerebrovascular mortality and morbidity .
All-cause mortality and coronary heart disease were not reduced .
There is lack of good evidence on withdrawal due to adverse events .
BACKGROUND Hypertension is an important risk factor for adverse cardiovascular events including stroke , myocardial infa rct ion , heart failure and renal failure .
The main goal of treatment is to reduce these events .
Systematic review s have shown proven benefit of antihypertensive drug therapy in reducing cardiovascular morbidity and mortality but most of the evidence is in people 60 years of age and older .
We wanted to know what the effects of therapy are in people 18 to 59 years of age .
OBJECTIVES To quantify antihypertensive drug effects on all-cause mortality in adults aged 18 to 59 years with mild to moderate primary hypertension .
To quantify effects on cardiovascular mortality plus morbidity ( including cerebrovascular and coronary heart disease mortality plus morbidity ) , withdrawal due adverse events and estimate magnitude of systolic blood pressure ( SBP ) and diastolic blood pressure ( DBP ) lowering at one year .
Investigating strategies to improve attendance at screening visits in a randomized trial
Background A common method of recruiting for r and omized trials is to send letters to potentially eligible patients inviting them to a screening appointment . In 3 consecutive UK studies the proportion attending from those invited fell from 49 % [ 1 ] in 1994 - 1997 and 42%[2 ] in 1998 - 2001 to 13 % at the beginning of an ongoing study in 2007 . Procedures were similar in the 3 trials except that in 2007 the Patient Information Leaflet ( PIL ) was enclosed with the invitation letter . In order to underst and whether the contents and /or style of invitation would explain the declining trend , 2 separate r and omized comparisons were undertaken during the recruitment for the ongoing study
