Central Blood Pressure and Variability Evaluation

AAAAbdominal Aortic Aneurysm1 more

Background: A sub-study of the AARDVARK (Aortic Aneurysmal Regression of Dilation: Value of ACE-Inhibition on RisK) trial indicated a statistically significant association between central blood pressure (BP) variability and abdominal aortic aneurysm (AAA) growth. The role of anti-hypertensive adherence has not been explored in the context of AAA growth. Objective: To confirm whether higher central BP variability is associated with higher AAA growth rates and to examine the effect of medication adherence on AAA growth rates in a prospective longitudinal cohort study. Methods: Up to 175 patients will be recruited over ten months from two sites with standardised quality control of AAA, BP and antihypertensive non-adherence measurement. Patients (>55 years), with AAAs ≥3cm in diameter (including AAA ≥5.5cm, not proceeding to surgery) will be recruited and undergo AAA ultrasound (US), BP (peripheral and central) and antihypertensive non-adherence measurements every four months (+/- one month) for 24 months. Ambulatory BP variability data will be collected. Data on medication adherence and beliefs around medications will be collected with validated questionnaires. Analysis: Primarily, the relationship between central diastolic BP visit-to-visit variability and AAA growth (estimated by multilevel modelling) based on US measurements and secondarily the relationship between central diastolic BP variability and time taken to reach the threshold for AAA repair (5.5 cm) or rupture.

Low-dose Colchicine Inhibit Abdominal Aortic Aneurysm Growth Trial

ColchicineAbdominal Aortic Aneurysm1 more

COIN trial is a a prospective, randomized, placebo-controlled, double-blind, multicenter clinical study. Approximately 230 patients with small abdominal aortic aneurysms (AAA) will be randomly allocated to low-dose colchicine group or placebo group. All study patients will be followed up in the outpatient clinic every 3 months and undergo CTA scans after 24 months from randomization. The primary objective is to test the hypothesis that low dose colchicine can inhibit the progression of AAA diameter. The secondary objective is to test the hypothesis that low dose colchicine can inhibit the progression of AAA volume, reduce the incidence of clinical outcomes associated with AAA, reduce the incidence of major adverse cardiovascular events and all-cause mortality.

Aortic AneurysmAbdominal

Design A multi-centre pilot study investigating the acceptability and adherence of a prehabilitation on patients requiring abdominal aortic aneurysm repair. Setting 3 NHS Hospital Vascular Surgery Clinics in the UK. Imperial College Healthcare NHS Trust Cambridge University Hospitals NHS Trust Mid and South Essex NHS Trust Patient Population Patients referred to secondary/tertiary vascular clinic for the repair of asymptomatic infrarenal Aneurysm Intervention: Baseline (conducted face-to-face): After providing written informed consent, participants will be provided with information about the prehabilitation programme. The following data will also be collected: baseline demographic characteristics (including age, sex and ethnicity), body mass index (BMI), medical history (including time since diagnosis), current medication, aneurysm diameter, health-related quality of life (EQ-5D-5L and EQ-VAS), smoking status and psychological wellbeing (using the Hospital Anxiety and Depression Scale; HADS) and Frailty assessments( QMortality Index, Electronic Frailty Index, Rockall score). Participants will also complete a 6-minute walking test(6MWT).

The PREHAAAB Trial: Multimodal Prehabilitation for Patients Awaiting Open Abdominal Aortic Aneurysm...

Abdominal Aortic Aneurysm

An abdominal aortic aneurysm is a condition where the major artery in the abdomen becomes larger than usual. Over time, as it continues to grow, the wall of the artery weakens and there is a risk that the artery can burst causing internal bleeding and death. Aortic aneurysms are fixed when they reach a certain size to prevent that outcome. The surgery to fix them is a major, high-risk surgery that is associated with a lot of complications and a slow recovery back to normal. The time between diagnosis and surgery is called the pre-operative period and is a key time to optimize a patient's health in order to ensure the best possible outcomes following surgery. This study will look at whether a multidisciplinary pre-operative program that involves exercise training, nutritional advice and supplementation, and psychosocial support will reduce complications following surgery. This program should decrease complications and speed up a patient's recovery back to normal after surgery. It is also a way for patients to take ownership of their disease and play an active role in their health care journey. The benefits from this program will go beyond the pre-operative time frame, as the habits and knowledge gained will improve their health over their lifetime. This study will also assess the economic impact and cost of a program like this.
