The relationship between the kidneys and the heart: How the kidneys affect heart rate

A Harvard University study found that more people die from heart-related illnesses caused by kidney complications than from kidney failure or needing dialysis.

Chronic kidney disease is prevalent in more than 1 in 7 adults. Normal kidney function has become a much rarer phenomenon these days. According to Harvard Health, kidney disease is also difficult to detect early because there are no symptoms in the early stages. However, these silent symptoms worsen over time and lead to serious complications.

Are the kidneys related to the heart? yes. High blood pressure and diabetes are the most common causes of chronic kidney disease, and these two also affect the heart. According to Dr. Martina McGrath, a transplant nephrologist at Harvard Brigham and Women’s Hospital, there can be overlap in the underlying causes of kidney disease and heart disease, and in the treatments for both diseases. According to Dr. Martina McGrath, in most cases people die from heart-related illnesses caused by kidney complications, rather than kidney failure or the need for dialysis.

Dr. Santosh Kumar Dora, Senior Cardiologist, Asian Heart Mumbai Learn more about the relationship between the kidneys and heart. Read to the end to understand what exactly is going on.

How do the kidneys affect heart rate?

Medical research is uncovering the complex relationship between heart disease and kidney function. Previously, these two organ systems were considered separate entities with separate pathologies. The interactions between them are now well understood and are often referred to as “cardiorenal” diseases.

common risk factors

It is well established that hypertension, diabetes, obesity, and dyslipidemia are risk factors for both heart disease and kidney dysfunction. These conditions often coexist, exacerbating each other’s progression, and have synergistic effects on cardiovascular and renal health.

disease progression

Inflammatory processes, oxidative stress, and endothelial dysfunction play pivotal roles in the development and progression of both heart disease and renal dysfunction.

correlation

Fluid and electrolyte imbalances in chronic kidney disease can lead to high blood pressure and fluid overload, which puts strain on the heart and affects heart rate. Similarly, heart failure can cause decreased blood flow to the kidneys, impairing their function. Therefore, these two diseases coexist and exacerbate each other’s symptoms.

How can we care for both organs?

Dr. Santosh Kumar Dora says, “Naturally, both organs help take care of the other. Read below to find out how.”

How the heart gives clues about the kidneys: Echocardiography and cardiac magnetic resonance imaging (MRI) provide detailed insight into the structure and function of the heart and can identify subtle abnormalities that indicate underlying kidney dysfunction.

How the kidneys give clues about the heart: Biomarkers such as troponin and brain natriuretic peptide (BNP) provide valuable information regarding cardiovascular disease outcomes in patients with kidney disease.

conclusion

Both treatments overlap as well. Although there are numerous preclinical and clinical studies showing that targeted therapies in common pathways may alleviate cardiorenal syndrome, lifestyle modification and patient education remain essential elements in the management of cardiorenal syndrome. . Therefore, encouraging a heart-healthy diet, regular physical activity, smoking cessation, and medication compliance not only reduce cardiovascular risk but also preserve kidney function.
