[Q]: Anxiety disorders increase risk of future cardiovascular disease (CVD) and mortality, even after controlling for confounds including smoking, lifestyle, and socioeconomic status, and irrespective of a history of medical disorders. While impaired vagal function, indicated by reductions in heart rate variability (HRV), may be one mechanism linking anxiety disorders to CVD, prior studies have reported inconsistent findings highlighting the need for meta-analysis.', 'Studies comparing resting-state HRV recordings in patients with an anxiety disorder as a primary diagnosis and healthy controls were considered for meta-analysis.', "Meta-analyses were based on 36 articles, including 2086 patients with an anxiety disorder and 2294 controls. Overall, anxiety disorders were characterized by lower HRV [high frequency (HF): Hedges' g\u2009=\u2009-0.29. 95% CI: -0.41 to -0.17, p\u2009<\u20090.001; time domain: Hedges' g\u2009=\u2009-0.45, 95% CI: -0.57 to -0.33, p\u2009<\u20090.001] than controls. Panic disorder (n\u2009=\u2009447), post-traumatic stress disorder (n\u2009=\u2009192), generalized anxiety disorder (n\u2009=\u200968), and social anxiety disorder (n\u2009=\u200990), but not obsessive-compulsive disorder (n\u2009=\u200940), displayed reductions in HF HRV relative to controls (all ps\u2009<\u20090.001).

[Q]: the use of antihypertensive medication in older people in order to prevent cardiovascular events is well established. The use of such agents has been encouraged by incentive schemes in the United Kingdom including the Quality and Outcomes Framework. In addition, many guidelines recommend good blood pressure (BP) control in the elderly. However, in older people antihypertensives can cause adverse effects related to hypotension.', 'the aim of this study was to assess the prevalence of low\xa0BP and impact on outcomes, particularly in the presence of antihypertensive treatment, in a primary care population of older people.', 'a retrospective observational cohort study in people over the age of 70 years registered with primary care providers in Kent.', 'a total of 11,167 patients over 70 years old were analysed, 6,373 female (57%). Systolic blood pressure (SBP) was below 120 mmHg in 1,297 people (844 on antihypertensives), below 110 mmHg in 474 (313 on antihypertensives) and below 100 mmHg in 128 (89 on antihypertensives). Hypotension was independently associated with mortality, acute kidney injury and hospital admission.

[Q]: This study's objective was to determine the test characteristics of pedal pulse palpation in the diagnosis of peripheral arterial disease (PAD) when compared to the more widely recommended screening tool, the ankle-brachial index (ABI).", 'We screened patients > 50 years of age for PAD within primary care clinics in Houston. PAD was diagnosed by an ABI of <0.9. At each visit, pedal pulse palpation was performed for each leg. Of the patients who screened positive for PAD by ABI, we determined the sensitivity, specificity, and positive predictive value of pulse palpation.', 'We enrolled 403 patients with a mean age of 63.8 +/- .36 years. The prevalence of PAD was 16.6% (67 patients total). Of the 45 patients with disease involving their left leg, 37 (82.2%) had a palpable pulse. Of the 37 patients with disease involving their right leg, 25 (67.6%) had a palpable pulse. The sensitivity of a non-detectable pulse for the diagnosis of PAD was 17.8% and 32.4% for the left leg and the right leg, respectively. The specificity of pulse palpation for the detection of PAD was 98.7% and 97.8% for the left leg and the right leg, respectively.
