Aortic Pulse Wave Velocity Predicts Cardiovascular Events and Mortality in Patients Undergoing Coronary Angiography: A Comparison of Invasive Measurements and Noninvasive Estimates

Aortic pulse wave velocity (PWV) is directly related to arterial stiffness. Different methods for the determination of PWV coexist. The aim of this prospective study was to evaluate the prognostic value of PWV in high-risk patients with suspected coronary artery disease undergoing invasive angiography and to compare 3 different methods for assessing PWV. In 1040 patients, invasive PWV (iPWV) was measured during catheter pullback. Additionally, PWV was estimated with a model incorporating age, central systolic blood pressure, and pulse waveform characteristics obtained from noninvasive measurements (estimated PWV). As a third method, PWV was calculated with a formula solely based on age and blood pressure (formula-based PWV). Survival analysis was based on continuous PWV as well as using cutoff values. After a median follow-up duration of 1565 days, 24% of the patients reached the combined end point (cardiovascular events or mortality). Cox proportional hazard ratios per 1 SD were 1.35 for iPWV, 1.37 for estimated PWV, and 1.28 for formula-based PWV (P<0.0001 for all 3 methods) in univariate analysis, remaining statistically significant after comprehensive multivariable adjustments. In a model including a modified risk score for coronary artery disease, iPWV and estimated PWV remained borderline significant. The net reclassification improvement was significant for iPWV (0.173), formula-based PWV (0.181), and estimated PWV (0.230). All 3 methods for the determination of PWV predicted cardiovascular events and mortality in patients with suspected coronary artery disease. This indicates that iPWV as well as both noninvasive estimation methods are suitable for the assessment of arterial stiffness, bearing in mind their individual characteristics.

[Awareness, treatment and control of blood pressure according to place of recruitment and sex in the May Measure Month 2018 survey in Spain]

OBJECTIVE

To analyse the data, according to recruiting place and sex, of the survey May Measure Month in 2018 (MMM18) in Spain, promoted by the International Society of Hypertension.

METHODS

Subjects more than 18 years old were studied. MMM18 protocol was performed. Volunteers were recruited through the Spanish Society of Community Pharmacy (SEFAC) and the Spanish Society of Hypertension (SEH-LELHA). General linear models of blood pressure (BP) were carried out in subjects with and without treatment, and adjusted by age, sex, tobacco use, obesity and recruitment site.

RESULTS

7 511 individuals (mean age 51.7 ± 19.6 years, 36.8% males) were screened. Systolic and diastolic BP was higher in males (129.0-16.7/119.6-18.2 mmHg) (78.3-11.1/74.8-10.7 mmHg) (p < 0.001). There was a linear relationship between systolic BP, age and sex, with higher values in males (11.2 mmHg in untreated and 4.5 mmHg in treated) (p < 0.001). Diastolic BP was inverted U-shaped, with highest level in males and between 50-55 years. The proportion of individuals with hypertension (pharmacies; public and clinical area) was 47.2% (54.2; 34.1 and 34.8%). Seventy-five percent were aware of their diagnosis (77.5; 61.5 and 69.2%), with 22% of them without pharmacological treatment (20.7; 26.0 and 27.9%). Sixty-four point five percent of those under antihypertensive treatment met targets (62.9; 65.6 and 69.1%) (p < 0.001).

CONCLUSIONS

There is big room for improvement in MMM indicators in Spain. Nearly half of subjects are hypertensive. Of those aware of their condition, 1 in 5 did not follow pharmacological treatment and of those treated, 1 in 3 did not meet targets. BP levels were significantly higher in males. Our study suggests that gender differences described should be considered in the BP thresholds established.

May Measurement Month 2018: an analysis of blood pressure screening results from Spain

Elevated blood pressure (BP) is the single most important contributing risk factor to the global disease burden, leading to over 10 million deaths each year. In Spain, hypertension (HTN) affects around 20% of the adult population and remains the greatest attributable cause of cardiovascular mortality. May Measurement Month (MMM) is a worldwide initiative aimed at increasing awareness of HTN and to improve the lack of screening programmes worldwide. An opportunistic cross-sectional survey of volunteers aged 18 and over was carried out in May 2018. Blood pressure measurement, the definition of HTN and statistical analysis followed the standard MMM protocol. Anthropometric data and responses to questionnaires on demographic, lifestyle, and environmental factors were obtained as additional information. Screening sites mainly in community pharmacies, universities, primary care centres, HTN units, and cardiovascular departments in hospitals were set up across Spain as part of this initiative. In total, 7646 individuals (63.5% female) were screened during MMM18. After multiple imputation, 40.0% had HTN, of whom 74.4% were aware of their diagnosis and 69.6% were taking antihypertensive medication. Of individuals not receiving antihypertensive medication, 16.9% were hypertensive. Of individuals receiving antihypertensive medication, 36.4% had uncontrolled BP. MMM18 almost doubled the number of participants of MMM17 and was the largest BP screening campaign ever undertaken in Spain, showing that in the absence of systematic screening programmes for HTN, MMM can identify a great number of individuals at risk, increasing their awareness and attracting the interest of the healthcare system in Spain.

Clinical inertia in hypertension: a new holistic and practical concept within the cardiovascular continuum and clinical care process

Purpose: Recognition of clinical inertia is essential to improve the control of chronic diseases. Although it is very intuitive, a better interpretation of the concept of clinical inertia is lacking, likely due to its high complexity. Materials and Methods: After a review of the published articles, we propose a practical vision of inertia, contextualized within the clinical process of hypertension care. Results: This new vision enables the integration of previous terms and definitions of clinical inertia, as well as proposing specific strategies for its reduction. Conclusion: Although some concepts should be considered as 'justified inertia' or 'investigator inertia', the idea that inertia may be present throughout the continuum of care gives physicians a holistic view of the problem that is easily applicable to their clinical practice. Measures to overcome inertia are complicated because of the intrinsic complexity of the concept.
