- In the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study, the primary composite end point of cardiovascular death, stroke, and myocardial infarction was reduced by losartan versus atenolol in patients with hypertension and left ventricular hypertrophy. The objective of this post hoc analysis was to determine the influence of pulse pressure on outcome. Patients were divided into quartiles of baseline pulse pressure. Cox regression, including baseline Framingham risk score as a covariate, was used to compare risk in the quartiles. In the atenolol group, there were significantly higher risks in the highest versus lowest quartile for the composite end point 28% (confidence interval [CI], 2% to 62%; P=0.035), stroke 84% (CI, 32% to 157%; P<0.001), and total mortality 41% (CI, 7% to 84%; P=0.013). Risk for myocardial infarction was 44% higher (CI, -5% to 120%; P=0.089). The risks in the losartan group also increased with increasing quartile, but were lower than in the atenolol group, and differences between the highest and lowest quartiles were not significant: composite end point 12% (CI, -13% to 44%; P>0.2), stroke -5% (CI, -34% to 37%; P>0.2), myocardial infarction 30% (CI, -13% to 94%; P>0.2), and total mortality 32% (CI, -1% to 76%; P=0.062). In patients with hypertension and left ventricular hypertrophy in the LIFE study, there were significantly higher risks, adjusted for the Framingham risk score, for the primary composite end point, stroke, and total mortality in the highest versus lowest quartile of pulse pressure with atenolol-based treatment. The risks in the losartan group also increased with increasing pulse pressure quartile, but were lower than those in the atenolol group, and were not significant.

Targeting the renin-angiotensin system for the reduction of cardiovascular outcomes in hypertension: angiotensin-converting enzyme inhibitors and angiotensin receptor blockers

- Agents that counteract the negative impact of the renin-angiotensin-aldosterone system (RAAS) are effective antihypertensives and reduce the risk of developing Type 2 diabetes. Contrary to common perception, angiotensin-converting enzyme inhibitors do not share the apparent benefit of angiotensin II receptor blockers (ARBs) in reducing risk of cardiovascular-disease outcomes, particularly stroke, in randomised clinical trials. RAAS agents, especially ARBs, are well tolerated. Use of ARBs alone or in combination with other classes of antihypertensive agents to lower blood pressure and/or medications to control other conditions (e.g., insulin sensitivity) reduces risk of cardiovascular disease outcomes and Type 2 diabetes with excellent tolerability. Selected issues related to use of RAAS agents as antihypertensive therapies (e.g., Type 2 diabetes, global risk management, multiple drug therapy and coronary heart disease) are addressed.

- The Losartan Intervention For Endpoint reduction in hypertension (LIFE) study reported that a losartan-based antihypertensive regimen reduced cardiovascular morbidity and mortality (composite of cardiovascular death, stroke, and myocardial infarction) more than therapy based on atenolol in patients with left ventricular hypertrophy and isolated systolic hypertension (ISH). Patients aged 55-80 years with blood pressures 160-200/<90 mm Hg were followed for a mean of 4.7 years. Blood pressure was similarly reduced in the losartan (n=660) and atenolol (n=666) ISH groups. There were 88 (6.6%) patients who experienced a stroke, 18 of which were fatal. Of patients experiencing strokes, 72.7% had an ischemic stroke. ISH patients in LIFE compared to the non-ISH group had a higher incidence of any stroke and embolic stroke, and similar incidences of fatal, atherosclerotic, and hemorrhagic/other strokes. The incidence of any stroke (40% risk reduction [RR], p=0.02), fatal stroke (70% RR, p=0.035), and atherothrombotic stroke (45% RR, p=0.022) was significantly lower in losartan-treated compared to the atenolol-treated patients. The 36% RR for embolic strokes in the losartan group was not statistically significantly (p=0.33) different from the atenolol group. These data suggest that losartan-based treatment is more effective than an atenolol-based treatment for patients with ISH and a high risk for stroke.
