February is American Heart Month, and a good time to think about how you can improve your heart health and live a heart healthy lifestyle.

High levels of an amino acid in the blood may slow down the mind. Vitamin B, however, has been shown to decrease this amino acid and improve brain function.

Implantable cardioverter defibrillators (ICDs) treat irregular heartbeats. While the devices have benefits, they also pose risks that doctors may not explain to patients.

Antioxidants - which are found in foods like soy products, coffee and fruits - have been shown to be healthy substances for the body. Researchers wanted to see if they could also lower risk of dementia and stroke.

Strokes caused by clots in blood vessels leading to the brain are typically treated with medications. Medical devices can also be used on clots, but they may offer no advantage over medication.

High blood pressure is the most important risk factor for stroke that you can change, according to the American Heart Association. A lower pressure may also ward off having additional strokes.

The blood thinners clopidogrel (Plavix) and aspirin both help save lives of heart patients by preventing clots. When used together, however, results have been mixed.
