Quitting smoking boosts health

When sustained over a period of time, angina can indicate that a person is having a heart attack. But even intermittent, brief episodes while taking a walk or climbing stairs can be alarming, reducing quality of life and affecting mental health. "Episodes of angina are scary, especially when patients have just had a heart attack. The symptoms are a signal that the heart is not getting enough oxygen, which affects the quality of people's daily lives," said Cresci. The study was published in the journal Circulation: Cardiovascular Quality and Outcomes.
