Did you know that constant anxiety - whether it's about your job, your relationships or your finances could fatal - so doctors should take time to check patients for anxiety, just as they'd check for other diseases. Chronic stress from constant worry also triggers a flood of hormones that can cause your heart to beat faster and pump harder, which leads to higher blood pressure, more wear and tear on cardiac blood vessels, and raises your risk for heart attacks and strokes.To protect yourself from what can be an extremely scary and painful stress response, you need to take steps to reduce your anxiety before it gets out of hand. Dr. Ragno recommends trying a breathing technique the next time you feel panicky. Simply inhale through your nose for a few seconds, and then exhale through your mouth until you empty the air out of your lungs. Repeat that until you calm down. It sounds ridiculously simple, but controlled deep breathing can reduce your heart rate and the production of stress hormones drastically. More extreme cases may need medication, but if you have even the slightest suspicion that you're having a heart attack - call 911.
