Hypertension & Heart Failure

New guidelines link heart, kidney, and diabetes risks

According to the American Heart Association, American College of Cardiology, American Diabetes Association, and American Society of Nephrology guidelines, people with type 2 diabetes often face overlapping risks involving the heart, kidneys, and metabolism — and these guidelines are designed to help doctors manage all of those risks together rather than treating each one separately. This matters because heart disease and kidney disease are closely connected to diabetes, meaning addressing them as a group can lead to better overall care. These guidelines are intended to give doctors — including heart specialists, diabetes specialists, kidney specialists, and primary care providers — a shared, up-to-date approach to protecting their patients' health.

Plant-based eating may cut heart disease risk

This research combined data from 23 studies and found that people with type 2 diabetes — and adults generally — who closely followed the Planetary Health Diet (an eating pattern built around vegetables, fruits, whole grains, legumes like beans and lentils, and nuts, with little red meat or processed food) had about 17–18% lower chances of death or serious heart problems like heart attacks or strokes. The benefit wasn't all-or-nothing: meaningful risk reductions appeared once people reached a moderate-to-high level of the diet, suggesting that gradually eating more plants and less processed meat — even starting with one meal today — may matter. The researchers note these studies show a strong link but can't yet prove the diet directly causes these better outcomes, so this is promising but not the final word.

New procedure may help beyond just blood pressure

Researchers found that a procedure called renal denervation — where nerves near the kidneys are disrupted to help lower high blood pressure — may also have benefits beyond just blood pressure control. The study found it was linked to improvements in heart rhythm problems, sleep apnea (a condition where breathing repeatedly stops during sleep), fasting blood sugar levels, and how well the heart's lower chambers relax and fill with blood. This is early research and hasn't yet changed treatment guidelines.

Plant-Based Diet May Help Your Heart Health

A study found that eating more plant-based foods — like vegetables, beans, nuts, and whole grains — while cutting back on red meat and processed meat may help improve heart health in people with type 2 diabetes. Researchers found this shift in eating habits was linked to a lower chance of serious heart problems like heart attacks or strokes. The findings suggest that what people put on their plate regularly can make a meaningful difference for their heart over time.

Ultra-Processed Foods May Raise Heart Disease Risk

Researchers found that eating a lot of ultra-processed foods — things like packaged snacks, fast food, sugary drinks, and ready-made meals that are made in factories with added sugars, unhealthy fats, salt, and artificial ingredients — is consistently linked to higher risks of serious heart problems like heart attacks or strokes, obesity, and death in people with type 2 diabetes and in the general population. These foods tend to be low in fiber and nutrients, which may make blood sugar control harder for people with diabetes. The researchers note that scientists are still working to fully understand exactly how and why these foods affect heart health.

High Coffee Intake May Raise Heart Attack Risk

A large analysis combining data from over 2.8 million people found that drinking higher amounts of coffee was linked to a 48% greater chance of having a heart attack compared to drinking very little coffee — though it did not appear to raise the overall risk of other heart conditions like heart failure. For people with type 2 diabetes, who already face a higher risk of serious heart problems like heart attacks or strokes, this is worth noting, though the research doesn't tell us exactly how many cups cross the line. Your doctor can help weigh whether current coffee habits make sense alongside any other heart or blood sugar concerns.

Do routine health checks actually prevent heart disease?

Researchers looked at whether routine 'health check' programmes — where adults get screened for things like high blood pressure or risk of serious heart problems like heart attacks or strokes — actually help people stay healthier in countries where healthcare is free at the point of use. The idea is that catching these risks early, including in people with type 2 diabetes, might allow doctors to step in sooner and potentially prevent serious illness down the line. This is early research and hasn't yet changed treatment guidelines.

Water pills might not be needed as long as you think

Researchers found that diuretics — water pills commonly used to treat heart failure and high blood pressure — are sometimes kept going longer than needed, which can lead to problems like falls, low blood pressure, and kidney issues, especially in older adults taking multiple medications. After reviewing 41 international guidelines and tools, researchers found that clear, step-by-step guidance on how to safely reduce or stop these medications is largely missing. This is a new finding about a gap in existing guidance, not a new treatment or safety alert.

Check your BP regularly if you have diabetes

According to clinical guidelines, people with type 2 diabetes and high blood pressure should have their blood pressure checked at every routine visit, or at least every six months, and are encouraged to monitor it at home as well. Guidelines recommend that if it can be safely achieved, the target blood pressure for these patients should be below 130/80 mmHg — and even lower (below 120 on the top number) for those at higher risk for serious heart problems like heart attacks or strokes. These targets are meant to be decided together by patients and their doctor, taking into account each person's overall health, personal preferences, and how well they might tolerate blood pressure medications.

Exercise Plans That Work for Your Type 2 Diabetes

A study found that for people with type 2 diabetes, regular exercise — such as gradually increasing physical activity over time, tailored to what each person can safely handle — is a key part of managing the condition and improving overall health. Researchers found that factors like a person's social situation, mental well-being, and access to facilities all affect whether people stick with an exercise routine. The study also found that having trained professionals guide the process helps turn an exercise plan on paper into something that actually works in real life.

Ultra-processed foods may harm diabetes control

A study found that eating too many ultra-processed foods — things like packaged snacks, sugary drinks, fast food, and ready-made meals — is linked to poor health outcomes for people with type 2 diabetes, partly because these foods tend to be loaded with saturated fat (the kind of fat that can clog arteries) and added sugars while offering little real nutrition. Researchers found that this combination of excess calories and low nutritional value can make blood sugar control harder to manage. The study highlights that the more ultra-processed foods people eat on a regular basis, the greater the impact on their overall health.
