What You Should Know About Kidney Stones and Heart Health

As a general rule, kidney stones have been a mans disorder. But this correlation may soon become a misnomer as the risk of women developing kidney stones is rising. Nationally, the number of emergency department visits for the treatment of upper urinary tract stones has grown to more than 3.6 million, and women are responsible for the greatest increase in visits. …

A Heart-Healthy Lifestyle Now May Prevent Events Later On

Cardiovascular disease doesnt happen overnight. Its a slow process that starts as early as age 5. From the moment fatty plaques appear in the arteries, the chance they will eventually block blood flow to the heart, brain or kidneys steadily grows.

Controlling Two Key Risk Factors May Double Heart Protection

If you have high blood pressure-a reading of 140/90 mm Hg or higher-your heart risk is double that of someone with normal blood pressure. But did you know that lowering your blood pressure with medications reduces your risk only 20 to 25 percent? That means youre still vulnerable to heart disease.

Making Sense of the Salt Debate

High blood pressure (hypertension) is a risk factor that contributes to heart attack, stroke and kidney disease. A diet low in sodium (the main ingredient in salt) can help prevent hypertension. The question is, how little sodium should you consume?For decades, it has been known that blood pressure starts to rise when sodium consumption exceeds 2,300 mg/day. This has led most U.S. and European societies to set the upper limit of sodium consumption at 2,300 mg/day.

Treating Arteries in the Kidneys Helps Overcome Resistant Hypertension

One way to a healthier heart may just be through the kidneys. Specifically, at least one effective solution to resistant hypertension appears to be a procedure called renal denervation. Recent research suggests that injuring the nerves inside the arteries of the kidneys with catheter ablation can diminish the response of the brains sympathetic nervous system, which activates what is commonly referred to as the fight or flight response in the body. The concern is that part of that response includes a faster heart rate and elevated blood pressure.

Heart Surgery May be Best to Treat CHD in Dialysis Patients

An estimated 30 to 60 percent of kidney failure patients on dialysis have coronary heart disease, a narrowing of the small arteries that supply blood to the heart. Arteries blocked with plaque can be opened with angiography and stenting or with coronary artery bypass grafting (CABG), which requires open surgery.

Chronic Kidney Disease May Pose Greater Heart Risk than Diabetes

The risk type 2 diabetes poses to heart health is well established, but individuals with chronic kidney disease (CKD) may face even higher risks of having a heart attack than those with diabetes. Thats among the findings of a large population-based study published online June 18 in the Lancet. But CKD did not rise to the level of a coronary heart disease (CHD) risk equivalent, meaning that it does not put a person at the same risk of having a heart attack, also known as a myocardial infarction or MI, as does a history of heart disease. The study notes that the data show that diabetes alone and chronic kidney disease alone… do not increase the rate of myocardial infarction to the same extent as does a history of coronary disease, and therefore do not support the use of the term coronary heart disease risk equivalent for either disorder.

Research Shows Risky Weight Loss Efforts May Hurt Kidneys

With one in five overweight Americans suffering from kidney disease, the role of weight loss in managing the condition is crucial. But certain lifestyle choices can further damage kidney function, according to a Cleveland Clinic study published online in the February issue of the International Journal of Obesity. Led by Cleveland Clinic nephrologist Sankar Navaneethan, MD, researchers examined the food choices and lifestyle habits of nearly 11,000 overweight Americans. They found that the typical American diet includes 1.2g of protein per kilogram of body weight each day.

I have diabetes and am on an ACE-inhibitor, because my doctor says it also helps protect the kidneys. Ive developed a cough. My doctor said something about trying an ARB instead, but Im doing well on this drug, except for the cough. Any thoughts?

Ask The Doctors: January 2012 Women’s Edition

The connection between calcium supplements and heart disease is unclear. Some studies have shown risk, while other studies have shown benefit. The most recent meta-analysis of clinical trials in the British Medical Journal found a mildly increased risk of heart attack and other major adverse cardiac event in women taking calcium supplement. Therefore, the current recommendation is that you talk with your primary care physician, who will balance your risk of heart disease with your risk of osteoporosis.

Encouraging Developments in Maintaining Heart and Kidney Health

Your heart relies on your kidneys to help filter waste materials from your blood and maintain fluid and chemical levels for optimal blood pressure. And like all organs, your kidneys need a strong heart to keep pumping oxygenated and nutrient-filled blood to them to remain healthy and functional. Even though your renal and cardiovascular systems are so inter-dependent, patients with chronic kidney disease (CKD), the slow loss of kidney function over time, have historically not been represented in cardiovascular clinical trials.

I was diagnosed with coronary artery disease about a year ago and have since had one stent put in. I take my medications and try to live a healthy lifestyle with regular exercise and a good diet, but I frequently find myself worrying about my heart and my life expectancy. Any advice?
