The treatment of chronic but stable coronary artery disease is based on the stages of chronic kidney disease (CKD) stages G1-2 and stages G3-G5, distinguishing between advanced kidney disease (stages G3-G5) and end-stage kidney disease (G5D) treated by dialysis. In Germany, national guidelines are followed for patients with normal kidney function in addition to the recommendations of Kidney Disease - Improving Global Outcomes (KDIGO) for CKD patients. These guidelines focus on standard of care and include treatment with aspirin, statins, beta-blockers, inhibitors of the renin-angiotensin system, and sodium glucose cotransporters for patients with cardiovascular disease. ⋯ Younger patients appear to benefit from surgical interventions. Treatment of acute events is currently administered independent of the patient's kidney function, but there is no consensus yet on the best strategy. The focus of our efforts should be, via more controlled studies, to avoid "navigating through the darkness" to reach the end of the tunnel.

Chronic kidney disease (CKD) is associated with substantial cardiovascular morbidity and mortality. This is mediated by the high prevalence of traditional cardiovascular risk factors in patients with CKD such as arterial hypertension and diabetes mellitus, but also by the presence of CKD-specific so-called nontraditional cardiovascular risk factors such as vascular calcification, uremic toxins, uremic dyslipidemia as well as inflammation and oxidative stress. Therefore, the primary and secondary prevention of cardiovascular disease represents an integral part of nephrology. This entails optimal control of blood pressure and diabetes, therapy of the uremic dyslipidemia as well as lifestyle-modifying factors such as weight reduction and smoking cessation.

Valvular heart disease is a common comorbidity in patients with impaired renal function, especially in those with end-stage renal disease undergoing dialysis. Sclerosis and calcification of the heart valves and the valve ring are particularly relevant in the etiology of the diseases. ⋯ Catheter-based treatment options have emerged as an effective and safe alternative for patients >75 years and/or with increased surgical risk. Consequently, in patients with appropriate anatomy and elevated risk, interventional treatment options should also be discussed in the heart team.

Recurrent stroke is a frequent event and clinical trials that addressed the best secondary prevention are sparse. If patients take a thrombocyte aggregation inhibitor (TAI) before the recurrent stroke, clopidogrel can be chosen instead of aspirin or vice versa but evidence is lacking. A 3-week period of dual antiplatelet treatment might be a good alternative after acute reinfarction. ⋯ Patients with ICH associated with oral anticoagulation (OAC) and atrial fibrillation should be restarted on novel OACs, if there are no relevant contraindications and the risk of ischemia is high. The anticoagulation treatment of patients with cerebral amyloid angiopathy is still a clinical dilemma as there is a high risk of recurrent ICH. These patients might be candidates for left appendage closure.
