Is there a relationship between chronic kidney disease (CKD) and heart health? Absolutely. In fact, the connection between the kidneys and the heart is stronger than many people realize. If you're living with CKD or caring for someone who is, understanding how these two vital organs affect each other is key to improving long-term health outcomes.

Chronic Kidney Disease and Heart Health: A Strong Connection

People with CKD are at a higher risk of developing heart disease. In many cases, cardiovascular disease becomes one of the leading complications of chronic kidney disease. This means managing your kidney health isn't just about your kidneys—it's also about protecting your heart.

Why CKD Increases the Risk of Heart Disease

When your kidneys aren’t functioning properly, several changes happen in the body that can directly increase cardiovascular risk. Here's how:

High Blood Pressure (Hypertension)

Chronic kidney disease can lead to high blood pressure, which damages the blood vessels over time. This increased pressure makes the heart work harder, significantly raising the risk of heart attacks and strokes.

Fluid Retention

When kidneys lose their ability to remove excess fluid efficiently, fluid retention occurs. This leads to swelling, especially in the legs and feet, and also contributes to elevated blood pressure and strain on the heart.

Mineral Imbalances

CKD can disrupt levels of key minerals like potassium, calcium, and phosphorus. These imbalances can:

• Interfere with normal heart rhythm





• Cause vascular calcification, or hardening of the arteries





• Increase the likelihood of cardiovascular events

Inflammation and Toxin Buildup

As kidney function declines, toxins build up in the body, leading to inflammation. Chronic inflammation is harmful to the heart and blood vessels, contributing to a higher risk of cardiovascular disease.

How to Reduce Cardiovascular Risk with CKD

While CKD increases the risk of heart disease, there are effective ways to lower that risk:

• Manage blood pressure with medication and diet





• Limit sodium intake to reduce fluid buildup





• Monitor mineral levels through regular blood work





• Eat a heart-healthy, kidney-friendly diet





• Stay physically active, as approved by your healthcare provider





• Avoid smoking and limit alcohol intake





• Work closely with your healthcare team to manage symptoms and prevent complications

These lifestyle and medical interventions can make a significant difference in both kidney function and heart health.

Protecting Your Heart Starts with Your Kidneys

Understanding the link between chronic kidney disease and cardiovascular health empowers you to take proactive steps toward better well-being. By managing CKD effectively, you also lower your risk of heart disease, ensuring a better quality of life and fewer complications down the road.

For anyone living with CKD, heart health isn’t just an afterthought—it’s a priority.
