There's nothing quite like the moment when your doctor says: "you have heart disease" (or diabetes). Sinners then repent with thoughts such as: "From this point on only healthy nutritious foods, daily exercise, and perhaps a bit of mindfulness." But do the sinners really repent or is that just something they tell themselves until the shock wears off, allowing their old ways to return?
It is becoming increasingly apparent that men and women have significant differences in their physiology, and subsequent manifestation of disease phenotypes. At the same time, scientists increasingly view physiology as it changes, rather than as static points in time. Those trends come together in a new paper in JAMA Cardiology, which looks at the most ubiquitous of cardiovascular diseases: high blood pressure.
Here's today's lineup: Why are there smell receptors in the kidney? ... Men and women see the world differently ... Spotify shows us how big data can inform and delight us ... and robots come for the village blacksmith.
The byproducts of dry-cured ham may be a source of anti-hypertensive bioactive peptides, which could help improve cardiovascular health.
The siren song of precision medicine is lost in the translation, from the laboratory to the bedside. Two studies suggest that precision medicine is more an aspirational term than reality.
The diagnostic criteria for high blood pressure are evolving. Should patients who are fine in the office, but hypertensive all the rest of the day, be considered as having high blood pressure? Should they be treated? Let's take a closer look.
High blood pressure is not a static event, it's dynamic, the result of multiple causes changing at different rates. Treating high blood pressure, or any disease, as a static process makes our models more inaccurate.
We cannot digest fiber, but some researchers believe fiber helps lower our blood pressure while maintaining cardiovascular health. It turns out that the fiber is being digested by the bacteria of our gut – and that process may play a role in controlling blood pressure.
There are probably few, if any, nutritional advisories that are as hotly debated as the appropriate level of sodium intake for healthy adults. Yes, the Dietary Guidelines and the American Heart Association recommend an upper limit of 2,300 mg sodium per day (about a teaspoon). But some new research is being added to the literature indicating that level of restriction may be too strict.
In most people's minds, high blood pressure is undoubtedly linked to salt intake. But there's another mineral that should also be considered — potassium. A recent review of several types of studies strongly indicates that it's not just a proper sodium level that helps one achieve, and maintain, normal blood pressure.
Vital signs matter. And they matter most when they're collected correctly and they provide accurate data. Dismiss them, or do them incorrectly, and the erroneous information will likely result in harmful medical decisions made on your behalf.
