Managing cardiovascular risk factors in patients with chronic kidney disease: pharmacological and non-pharmacological interventions in the Copenhagen CKD Cohort.

ABSTRACT:

Background

Although cardiovascular morbidity and mortality are substantial in patients with chronic kidney disease (CKD), guideline-directed treatment of cardiovascular risk factors remains a challenge.

Methods

Observational, cross-sectional study including patients aged 30-75 years with CKD stage 1-5 without kidney replacement therapy from a tertiary hospital outpatient clinic. Data were obtained through patient interview, clinical examination, biochemical work-up, and evaluation of medical records and prescription redemptions. Guideline-directed treatment was evaluated as pharmacological interventions: antihypertensive and lipid-lowering therapy including adverse effects and adherence estimated as medication possession ratio (MPR); and non-pharmacological interventions: smoking status, alcohol consumption, body mass index (BMI), and physical activity.

Results

The cohort comprised 741 patients, mean age 58 years, 61.4% male, 50.6% CKD stage 3, 61.0% office blood pressure ≤140/90 mmHg. Antihypertensives were prescribed to 87.0%, median number of medications 2 (IQR 1;3), 70.1% received renin-angiotensin system inhibition, 25.9% reported adverse effects. Non-adherence (MPR < 80%) was present in 23.4% and associated with elevated blood pressure (OR 1.53 (95% CI 1.03;2.27)) and increased urinary albumin excretion, P < 0.001. Lipid-lowering treatment was prescribed to 54.0% of eligible patients, 11.1% reported adverse effects, and 28.5% were non-adherent, which was associated with higher LDL cholesterol, P = 0.036. Overall, 19.2% were current smokers, 16.7% overconsumed alcohol according to Danish health authority recommendations 69.3% had BMI ≥ 25 kg/m², and 38.3% were physically active <4 hours/week. Among patients prescribed antihypertensives, 51.9% reported having received advice on non-pharmacological interventions.

Conclusions

Improved management of cardiovascular risk in patients with CKD entails intensified medical treatment and increased focus on patient adherence and non-pharmacological interventions.

Project description:Rationale & objectiveThe clinical significance of isolated diastolic hypertension in patients with chronic kidney disease (CKD) is unclear. We assessed the prevalence of isolated diastolic hypertension and its association with adverse kidney and cardiovascular outcomes in participants in the Chronic Renal Insufficiency Cohort (CRIC) study.Study designProspective cohort study.Setting & populationCRIC study participants with complete baseline data on systolic blood pressure (SBP) and diastolic BP (DBP) (N=5,621).ExposureIsolated diastolic hypertension defined as SBP ≤ 130 mm Hg and DBP >80 mm Hg.Reference groupNormotension, defined as SBP ≤ 130 mm Hg and DBP ≤ 80 mm Hg.OutcomesComposite kidney events (50% decline in estimated glomerular filtration rate or onset of kidney failure), composite cardiovascular events (myocardial infarction, heart failure, stroke, or peripheral arterial disease), and all-cause mortality.Analytical approachCox proportional hazards models adjusted for demographic, health behavior, and clinical covariates.ResultsOf the 5,621 participants, 347 (6.2%) had isolated diastolic hypertension. Among the 347 participants with isolated diastolic hypertension, there was no association between isolated diastolic hypertension and the composite kidney outcome (HR, 1.17; 95% CI, 0.93-1.47; P = 0.18), composite cardiovascular events (HR, 0.91; 95% CI, 0.65-1.27; P = 0.58), or all-cause mortality (HR, 0.82; 95% CI, 0.57-1.19; P = 0.30).LimitationsOlder age of cohort and low number of participants of Asian ethnicity limit generalizability of findings. A relatively small sample size is inadequate to detect modest associations with outcomes.ConclusionsIsolated diastolic hypertension was not associated with the risk of adverse kidney and cardiovascular events in participants with CKD.Plain language summaryClinicians frequently encounter patients with kidney disease who have controlled systolic blood pressure (BP) but high diastolic BP and do not know whether they should intensify BP treatment in an attempt to control the diastolic BP. We examined whether having controlled systolic BP but uncontrolled diastolic BP leads to worse heart and kidney outcomes in patients with chronic kidney disease. We did not find any such association. However, our study was relatively small and had a number of limitations. Till larger studies confirm or refute this finding, we recommend not increasing blood pressure medications to improve the diastolic BP control if the systolic BP is already well controlled in patients with chronic kidney disease.

Project description:BackgroundPatients with chronic kidney disease (CKD) require a personalised strategy for cardiovascular risk management (CVRM) to reduce their high risk of cardiovascular morbidity and mortality. Despite their high risk, patients with CKD appear to be underrepresented in randomised controlled trials (RCTs) for pharmacological CVRM interventions to reduce cardiovascular risk (pharmacological CVRM interventions). As a result, it remains unclear whether the efficacy of these interventions found in patients without CKD is similarly applicable to patients with CKD. This evidence map aims to provide an overview of the availability of the evidence from pharmacological CVRM trials for patients with CKD by assessing how often patients with reduced kidney function are specifically excluded or included from RCTs on pharmacological CVRM interventions and whether studies report efficacy estimates of interventions specifically for kidney patients.MethodsWe will perform a systematic literature search in ClinicalTrials.gov to identify relevant planned, ongoing, and completed RCTs on a broad range of CVRM medications after which we will retrieve the published protocols and papers via ClinicalTrials.gov itself, Embase, MEDLINE, or Google Scholar. We will include RCTs that investigate the efficacy of platelet inhibitors, anticoagulants, antihypertensives, glucose-lowering medication, and lipid-lowering medication on all-cause mortality, cardiovascular mortality, cardiovascular morbidity, and end-stage kidney disease in patients with a cardiovascular history or a major risk factor for cardiovascular disease. Two reviewers will independently screen trial records and their corresponding full-text publications to determine eligibility and extract data. Outcomes of interest are the exclusion of patients with reduced kidney function from RCTs and whether the study population was restricted to kidney patients or subgroup analyses were performed on kidney function. Results will be visualised in an evidence map.DiscussionThe availability of evidence on the efficacy and safety of pharmacological CVRM interventions in patients with CKD might be limited. Hence, we will identify knowledge gaps for future research. At the same time, the availability of evidence, or lack thereof, might warrant caution from healthcare decision-makers in making strong recommendations based on the extrapolation of results from studies to patients who were explicitly excluded from participation.Systematic review registrationPROSPERO CRD42022296746.
