Jerzy Jaśkowski claims that lowering blood pressure in older people to 140/80 was said to cause impaired consciousness and worsen dementia.
- He recommends not aiming to lower blood pressure rapidly in older adults.
- According to him, treatment should depend on age: the upper limit for blood pressure is 100 plus age, and the lower limit should not exceed 90 mm Hg.
What the authors write
In older people with high blood pressure, the aim should not be to lower it rapidly.
Lowering blood pressure to 140/80 in older people was said to cause impaired consciousness and worsen dementia.
Blood pressure should be adjusted according to age, and the stated upper limit is 100 plus age.
Jerzy Jaśkowski points out that it is important to keep the lower blood pressure number at no more than 90 mm Hg.
Treatment for high blood pressure should depend on age.

Among people aged 60–80, more intensive treatment reduced the rate of the primary cardiovascular outcome compared with standard treatment.
Aim of the study: The appropriate target for systolic blood pressure to reduce cardiovascular risk in older patients with hypertension remains unclear.
Results: Of the 9624 patients screened for eligibility, 8511 were enrolled in the trial; 4243 were randomly assigned to the intensive-treatment group and 4268 to the standard-treatment group. At 1 year of follow-up, the mean systolic blood pressure was 127.5 mm Hg in the intensive-treatment group and 135.3 mm Hg in the standard-treatment group. During a median follow-up period of 3.34 years, primary-outcome events occurred in 147 patients (3.5%) in the intensive-treatment group, as compared with 196 patients (4.6%) in the standard-treatment group (hazard ratio, 0.74; 95% confidence interval [CI], 0.60 to 0.92; P = 0.007).

Among people aged 75 years or older, an intensive blood pressure target was associated with a lower rate of cardiovascular events and deaths.
Aim of the study: To evaluate the effects of intensive (<120 mm Hg) compared with standard (<140 mm Hg) SBP targets in persons aged 75 years or older with hypertension but without diabetes.
Results: Among 2636 participants (mean age, 79.9 years; 37.9% women), 2510 (95.2%) provided complete follow-up data. At a median follow-up of 3.14 years, there was a significantly lower rate of the primary composite outcome (102 events in the intensive treatment group vs 148 events in the standard treatment group; hazard ratio [HR], 0.66 [95% CI, 0.51-0.85]) and all-cause mortality (73 deaths vs 107 deaths, respectively; HR, 0.67 [95% CI, 0.49-0.91]). The overall rate of serious adverse events was not different between treatment groups (48.4% in the intensive treatment group vs 48.3% in the standard treatment group; HR, 0.99 [95% CI, 0.89-1.11]).

A review of studies in people aged 65 years or older found fewer serious cardiovascular events with more intensive blood pressure lowering, without a significant increase in serious adverse events.
Aim of the study: The 2014 Eighth Joint National Committee panel recommended a therapeutic target of systolic blood pressure (BP) <150 mm Hg in patients ≥60 years of age, a departure from prior recommendation of <140 mm Hg. This study assessed the efficacy and safety of intensive BP-lowering strategies in older (age ≥65 years) hypertensive patients.
Results: We identified 4 high-quality trials involving 10,857 older hypertensive patients with a mean follow-up of 3.1 years. Intensive BP lowering was associated with a 29% reduction in MACE (RR: 0.71; 95% CI: 0.60 to 0.84), 33% in cardiovascular mortality (RR: 0.67; 95% CI: 0.45 to 0.98), and 37% in heart failure (RR: 0.63; 95% CI: 0.43 to 0.99) compared with standard BP lowering. Rates of myocardial infarction and stroke did not differ between the 2 groups. There was no significant difference in the incidence of serious adverse events (RR: 1.02; 95% CI: 0.94 to 1.09) or renal failure (RR: 1.81; 95% CI: 0.86 to 3.80) between the 2 groups. The fixed effects model yielded largely similar results, except for an increase in the risk of renal failure (RR: 2.03; 95% CI: 1.30 to 3.18) with intensive BP-lowering therapy. In older hypertensive patients, intensive BP control (systolic BP <140 mm Hg) decreased MACE, including cardiovascular mortality and heart failure.

In people with chronic kidney disease, an intensive blood pressure target was associated with lower mortality, although some adverse events were more common.
Aim of the study: The appropriate target for BP in patients with CKD and hypertension remains uncertain. We report prespecified subgroup analyses of outcomes in participants with baseline CKD in the Systolic Blood Pressure Intervention Trial.
Results: The prespecified main kidney outcome, defined as the composite of ≥50% decrease in eGFR from baseline or ESRD, occurred in 15 intensive group and 16 standard group participants (HR, 0.90; 95% CI, 0.44 to 1.83). After the initial 6 months, the intensive group had a slightly higher rate of change in eGFR (-0.47 versus -0.32 ml/min per 1.73 m2 per year; P<0.03). The overall rate of serious adverse events did not differ between treatment groups, although some specific adverse events occurred more often in the intensive group. Thus, among patients with CKD and hypertension without diabetes, targeting an SBP<120 mm Hg compared with <140 mm Hg reduced rates of major cardiovascular events and all-cause death without evidence of effect modifications by CKD or deleterious effect on the main kidney outcome.
