Cardiovascular Risk and Its Presentation in Chronic Kidney Disease.

Background/

Objectives

Patients with chronic kidney disease (CKD) are associated with a significantly elevated cardiovascular risk. The incidence and prevalence of mediated cardiac disorders and major adverse cardiac events (MACEs), such as heart failure, arrhythmias, acute coronary syndrome (ACS) based on coronary artery disease (CAD), stroke, venous thromboembolism, and peripheral artery disease, are significantly higher in CKD patients as compared with the general population.

Methods

This narrative review summarizes the current clinical understanding, the pathophysiological mechanisms, and the clinical consequences in the context of cardiovascular risk and disease in CKD.

Results

The impact of CKD on mediated cardiovascular disorders and elevated MACE prevalence is complex and multifactorial. The underlying mechanisms involve various traditional cardiovascular risk factors, such as arterial hypertension, smoking, dyslipidemia, and diabetes. Furthermore, CKD-specific molecular and pathophysiological factors, such as chronic inflammation and associated oxidative stress and endothelial cell dysfunction, pro-coagulatory status, uremic toxins and uremic lipids, progressive vascular calcification, and alterations in the regulation of the renin-angiotensin-aldosterone system (RAAS) and sympathetic activation cause an increased cardiovascular risk.

Conclusions

Understanding the complex disease mechanisms between CKD and elevated cardiovascular risk might contribute to optimizing individual patients' risk stratification and result in individualized diagnostic and treatment strategies via appropriate clinical biomarker application and individualized anti-inflammatory approaches.
