Sometimes my heart beats really fast and other times it feels like my heart skips a beat. Am I having a heart attack?

Most people have changes in their heartbeat from time to time. These changes in heartbeat are, for most people, harmless. As you get older, you're more likely to have heartbeats that feel different. Don't panic if you have a few flutters or if your heart races once in a while. If you have flutters AND other symptoms such as dizziness or shortness of breath (feeling like you can't get enough air), call 911.

Should I take a daily aspirin to prevent heart attack?

Aspirin may be helpful for women at high risk, such as women who have already had a heart attack. Aspirin can have serious side effects and may be harmful when mixed with certain medicines. If you're thinking about taking aspirin, talk to your doctor first. If your doctor thinks aspirin is a good choice for you, be sure to take it exactly as your doctor tells you to.

Does taking birth control pills increase my risk for heart disease?

Taking birth control pills is generally safe for young, healthy women if they do not smoke. But birth control pills can pose heart disease risks for some women, especially women older than 35; women with high blood pressure, diabetes, or high cholesterol; and women who smoke. Talk with your doctor if you have questions about the pill.

If you're taking birth control pills, watch for signs of trouble, including:

• Eye problems such as blurred or double vision
• Pain in the upper body or arm
• Bad headaches
• Problems breathing
• Spitting up blood
• Swelling or pain in the leg
• Yellowing of the skin or eyes
• Breast lumps
• Unusual (not normal) heavy bleeding from your vagina

If you have any of these symptoms, call 911.

Does using the birth control patch increase my risk for heart disease?

The patch is generally safe for young, healthy women. The patch can pose heart disease risks for some women, especially women older than 35; women with high blood pressure, diabetes, or high cholesterol; and women who smoke.

Recent studies show that women who use the patch may be exposed to more estrogen (the female hormone in birth control pills and the patch that keeps users from becoming pregnant) than women who use the birth control pill. Research is underway to see if the risk for blood clots (which can lead to heart attack or stroke) is higher in patch users. Talk with your doctor if you have questions about the patch.

If you're using the patch, watch for signs of trouble, including:

• Eye problems such as blurred or double vision
• Pain in the upper body or arm
• Bad headaches
• Problems breathing
• Spitting up blood
• Swelling or pain in the leg
• Yellowing of the skin or eyes
• Breast lumps
• Unusual (not normal) heavy bleeding from your vagina

If you have any of these symptoms, call 911.

Does hormone replacement therapy (HRT) increase a woman's risk for heart disease?

Hormone replacement therapy (HRT) can help with some symptoms of menopause, including hot flashes, vaginal dryness, mood swings, and bone loss, but there are risks, too. For some women, taking hormones can increase their chances of having a heart attack or stroke. If you decide to use hormones, use them at the lowest dose that helps for the shortest time needed. Talk with your doctor if you have questions about HRT.
