Heart Facts

Most people don’t realize that heart disease is the number-one killer of women - taking more lives than stroke, lung cancer, chronic obstructive pulmonary disease, and breast cancer combined.

But there's good news, too — heart disease is preventable!  You can reduce your risk by taking just a few simple steps, and Sister to Sister is here to help.

First, it helps to understand the basics: Your heart pumps blood throughout your body, making it one of your most important organs. When you have heart disease, your blood has a hard time getting to your heart and your other organs, and your heart has to work even harder to supply your body with the blood it needs – putting you at risk for a heart attack or stroke.

While you can’t control some heart disease risk factors, like age and family history, most can be controlled. Let Sister to Sister show you how to make good choices about how you treat your heart, so you can guard against heart disease and live a longer, better life!

Heart Disease 101

Thinking about your risk of heart disease can be frightening, but watching out for your health now can pay off in a big way. Making simple changes – like what you eat and how active you are – can lower your heart disease risk by as much as 82 percent!

What is heart disease?

Source: NHLBI
Heart disease is most commonly caused by narrowing or blockage of the coronary arteries – the blood vessels that supply blood to the heart itself. This is called coronary heart (or artery) disease, and it’s the main cause of heart attacks in women.

Fat, cholesterol, and other substances collect in the walls of your coronary arteries, leading to a buildup of plaque and a condition called atherosclerosis. As the coronary artery narrows, blood flow slows or stops, which causes angina (severe chest pain), shortness of breath, or a heart attack.

Who gets heart disease?

Heart disease is the leading cause of death for all women.

Women of all ages should be concerned about heart disease. The more you understand how your choices impact your risk, the more you’ll be able to reduce your risk of heart disease now and throughout your life.

What factors affect your risk of heart disease?

There are several risk factors for heart disease – and you can control most of them!

Factors you can control:

Factors you cannot control:

If you have high numbers for three or more of the risk factors you can control – cholesterol, blood pressure, diabetes, obesity (particularly your waist circumference) – you may have metabolic syndrome. A person with metabolic syndrome is twice as likely to develop heart disease as someone without metabolic syndrome. Be sure to talk with your doctor or health care provider to learn more.

How can you reduce your risk?

Heart Attack Signs

Men and women may differ in their experience of heart attack symptoms. For men, the most common sign of a heart attack is pain or pressure in the chest. Women are more likely than men to have unusual or "atypical" signs of a heart attack. Some of these symptoms may come and go.

Symptoms that every woman should know and pay attention to include:

Every minute counts!

Call 911 when you begin to have any of these symptoms. Do not wait more than five minutes before calling for help. Don't worry about symptoms being a "false alarm." Don't be concerned about bothering others. When you get to the hospital, ask for tests that would diagnose a heart attack. Treatment of heart attacks is most effective when administered as quickly as possible.

Know Your Numbers

You know the old saying, "knowledge is power"? Well, when it comes to heart disease this does, indeed, hold true. That's because knowing your numbers -- that is, numbers that measure certain heart disease risk factors -- takes the idea of heart disease out of the abstract and details any risk factors that might be a concern for you.

A simple heart disease screening -- the kind Sister to Sister provides for free at the Women's Heart Health Fair we hold annually across the country -- is how you can find out your numbers. (Of course, you can also get screened by your doctor or by using our Screening Locator tool.)

The chart below is a guide you can use to determine what numbers are ideal, what numbers put you at borderline risk for heart disease, and what numbers place you squarely in the high risk category.

Cholesterol

High cholesterol is a signal that you are at risk for heart disease and unfortunately, almost half of all women have borderline-high total cholesterol levels. But there are simple steps that can control cholesterol levels and allow women to live a healthy life. Even if you don’t have high cholesterol, it’s important to understand what it is and how to protect yourself and your family. It’s not as complicated as you think!

What is cholesterol?

Plaque Attack!
Plaque blocks the flow of blood through your arteries.

Source: NHLBI.
Cholesterol is a lipid, or fatlike substance, that travels through your blood and helps to form cell membranes and some hormones. The cholesterol that you need is produced naturally by your body. The problem starts when there is too much cholesterol in your body. This may come from food you eat, like meat or dairy products, that is rich in cholesterol. Or it is also possible that your body produces excess amounts of cholesterol or is unable to control cholesterol naturally. If you have too much cholesterol, it can stick to the walls of your arteries, keeping your blood from flowing freely. When this happens, the buildup is called plaque, and it can be a dangerous problem.

All cholesterol isn’t created equal!

Your total cholesterol is made up of three types of cholesterol – some good and some bad.

You can find out your cholesterol levels with a simple blood test. You should aim for a low total cholesterol number, a high LDL, a low LDL, and low triglycerides; our Know Your Numbers chart provides specific guidelines.

Lowering your levels

Once your cholesterol has been tested and you know your numbers, you’ll know how cholesterol is affecting your personal heart health. If cholesterol is negatively affecting your heart, don’t panic. These common-sense strategies can help:

Remember, you don’t have to take all these steps at once! Adopting even a few can make a big difference.

Blood Pressure

High blood pressure raises your risk of a heart attack or a stroke. High blood pressure creates space on the blood vessel walls where cholesterol deposits can build up, eventually blocking the blood flow.

If you have high blood pressure, you are not alone – a third of all women have it or takes medication to lower it. Fortunately, you can control your blood pressure and improve your heart health by making smart choices about food, exercise, and medication.

What is blood pressure?

Blood pressure is the push made as your heart pumps blood through your body. It’s recorded as two numbers: your systolic pressure (the pressure as your heart contracts to push blood out) "over" your diastolic pressure (the pressure as your heart fills with blood). Both numbers are important, and as we grow older, systolic pressure becomes especially important.

High blood pressure, also called hypertension, happens when the pressure in your heart rises and stays high over time. 140/90 mmHg is considered the threshold for high blood pressure, which is dangerous because it:

If your blood pressure is above normal (120/80 mmHg), but not considered high, then you may have prehypertension. This means that although you don't have high blood pressure now, you need to take action to prevent yourself from developing it later.

What can you do?

We often think of high blood pressure as a stress disease -- the result of overwork, lack of activity, and poor eating habits. The truth is, in most cases, experts don’t know what causes high blood pressure.

What they do know is that there is a lot you can do to keep your blood pressure under control and reduce your risk of heart disease. Taking these steps will also lower your risk of heart disease and lead you on the path to a healthier life. Remember, you don’t have to do them all at once. We will walk you through each step and break them down into smaller steps that are manageable for you.

A special note: If you are pregnant, or are taking oral contraceptives or hormone replacement therapy, you may experience a rise in your blood pressure so be sure to have it checked regularly. Pregnant women who have high blood pressure may be particularly at risk for certain problems.

Diabetes

People with diabetes are twice as likely as those without it to have a heart attack or stroke. In fact, heart disease is the leading cause of death for people with diabetes. Fortunately, by eating a healthy diet low in fat and sugar and staying active, you can control, delay, or even prevent diabetes.

What is diabetes?

Diabetes is a disease that prevents the body from properly using glucose, the sugar that gives our bodies their main source of energy. As we eat, most of our food is broken down into glucose. After we digest our food, this glucose enters our bloodstreams, and a hormone called insulin helps our bodies to put it to good use for growth and energy. However, the bodies of people with diabetes don’t have enough insulin or don’t use insulin properly. As a result, they have too much sugar in their blood and can develop serious health problems.

What’s the link between diabetes and heart disease?

Over time, high glucose levels, or high blood sugar, can cause a buildup of fatty materials on the blood vessel walls. This buildup may affect blood flow, leading to clogging, the hardening of blood vessels (atherosclerosis), and a greater possibility of a heart attack or stroke.

If you have diabetes, these problems in your blood vessel walls increase your chances of developing heart disease. A diagnosis of diabetes as an adult carries the same risk as already having one heart attack.

What types of diabetes are there?

There are three main types of diabetes.

When a person’s blood glucose levels are higher than normal but not high enough for a diagnosis of type 2 diabetes, they have prediabetes. If you’ve been diagnosed with prediabetes, you’ve been warned: it’s time to make safe choices to protect your health.

What are the signs and symptoms?

A blood glucose test can determine if you have, or are at risk, for diabetes. (Our Know Your Numbers chart provides specific guidelines.) People often don’t realize they have Type 2 diabetes because many of its symptoms can seem harmless. Recognizing the symptoms and getting early treatment can reduce complications down the road.

Some diabetes symptoms include:

If you have any of these symptoms, see your doctor right away.

What can you do?

You can do a lot to lower your chances of getting diabetes or to control it if you already have it. Taking these steps will also lower your risk of heart disease and give you a longer, healthier life!

Remember, you don’t have to take all these steps at once! Adopting even a few can make a big difference.

Physical Inactivity

Getting active doesn’t mean you have to take up running or join a gym. It starts with simply moving more during the day – by taking the stairs instead of the elevator, choosing a faraway parking spot, or walking to a coworker’s cubicle instead of picking up the phone to talk.

Even small increases in activity can lower your risk of heart disease enormously and help you feel better physically, emotionally, and mentally. You may experience less stress, be less likely to overeat, and feel calmer and happier. If that isn’t enough, think of the good example you’ll be setting for your family and friends!

How does physical activity help your heart?

Physical activity helps to control many of the risk factors for heart disease: cholesterol, diabetes, obesity, blood pressure and stress. So it isn’t surprising to find that 35 percent of deaths from heart disease could be avoided through increased activity. In fact, the cardiac risk of being inactive is comparable to the risk from smoking cigarettes.

How much is enough?

Ideally, women would engage in some physical activity for 30 minutes on most days of the week. Since that’s not always practical, it’s important to recognize that every incremental increase in physical activity yields some health benefit. Plus, small steps can easily lead to bigger ones!

What can you do to increase your level of physical activity?

Obesity

Nearly 65 million women age 20 and older in the United States are overweight or obese – but in many cases overweight and obesity can be controlled with a few simple lifestyle changes. By knowing the weight that is healthiest for you and taking small steps to reach it, you can lead a heart healthy life.

What do overweight and obesity mean?

Your healthy weight is based on your height, age, and other factors. Excess weight may come from muscle, bone, fat, or body water. Overweight means you weigh more than you should to be healthy. Obesity refers specifically to having too much body fat.

A higher weight or too much body fat increases your chances of developing high blood pressure, diabetes, and high cholesterol—all of which are risk factors for heart disease. In addition, excess body fat—especially abdominal fat—may produce substances that cause inflammation, which may raise heart disease risk. Obesity can also lead to congestive heart failure, a condition in which the heart can’t pump enough blood to meet your body’s needs.

What causes overweight and obesity?

Many factors can affect your weight, including:

How healthy is your weight?

The most commonly used method of determining if your weight is considered healthy is the body mass index (BMI), which is an index of weight adjusted for your height.

A BMI of 25.0 to 29.9 is considered overweight. A BMI of 30.0 or greater is considered obese. If your BMI is above 25, follow up with your doctor to evaluate your weight status and associated health risks.

Another factor in determining a healthy weight is your waist circumference. Fat deposits, especially around the abdomen, are an important independent risk factor for developing coronary artery disease. The ideal waist circumference for women is 35 inches or less.

You can measure your waist easily by wrapping a non-elastic measuring tape around your waist (above your belly button). Make sure that the tape is snug, does not squeeze your skin, and is parallel to the floor.

How can weight be controlled?

Many factors can cause you to be overweight or obese. Fortunately, you can do a lot to get your weight under control. Taking these steps will also lower your risk of heart disease and lead you on the path to a healthier life.

Remember, you don’t have to do everything at once! Even small changes can make a big difference to your heart.

Waist Circumference

When it comes to assessing whether your weight puts you at risk for heart disease, experts have found that it's not just total body fat that affects your health; it's also where fat is deposited around your body. In particular, fat deposits around the waist and abdomen are associated with greater health risks, including type 2 diabetes, high cholesterol, high blood pressure and heart disease.

This risk factor is very easy to check — no appointments necessary! You can measure your waist circumference yourself with any non-elastic measuring tape.

  • Before you measure, make sure that you have just breathed out normally; don't "suck in," because this will give you inaccurate results.
  • Wrap the measuring tape around your waist from one hip bone to the other. Make sure that the tape is snug but does not squeeze your skin, and that you are holding it parallel to the floor in a straight line across your waist.
  • Make a note of the measuring tape length.

As you measure your waist, keep in mind that 35 inches or less is considered a healthy waist circumference for women.

If you have a larger waist circumference, don't panic! You can improve your health by taking action. You can also pledge to get screened for heart disease and invite your friends to do the same.

BMI Calculator

The most commonly used method of determining if your weight is considered healthy is the body mass index (BMI), which is an index of weight adjusted for your height. Want to find out your BMI? Just type your height and weight into our BMI calculator, at right.

A BMI of 25.0 to 29.9 is considered overweight. A BMI of 30.0 or greater is considered obese. If your BMI is above 25, follow up with your doctor to evaluate your weight status and associated health risks.

Being overweight or having too much body fat (the definition of obesity) increases your chances of developing high blood pressure, diabetes, and high cholesterol—all of which are risk factors for heart disease. In addition, excess body fat—especially abdominal fat—may produce substances that cause inflammation, which may raise heart disease risk.

Obesity can also lead to congestive heart failure, a condition in which the heart can’t pump enough blood to meet your body’s needs. That's why it's important to know your BMI and talk with your doctor if it could be putting you at increased risk for heart disease.

Smoking

Smoking is a woman’s single biggest risk factor for a heart attack. It also puts you at risk for lung cancer, increases your chance of a stroke, and leads to coughing and shortness of breath. Furthermore, smoking affects the health of those around you – including your family.

The good news is that it’s never too late to quit. If you stop smoking, you’ll improve your health and reduce your long-term risks – and you’ll see immediate benefits, some within just a few hours!

How does smoking affect your heart?

The more cigarettes you smoke, the higher your risk of a heart attack. When you smoke:

Smoking can also aggravate other heart disease risk factors by:

Smoking can have additional negative effects on women who use oral contraceptives, giving them a higher risk of heart disease and strokes.

What about secondhand smoke?

Smoking isn’t just bad for you; it’s bad for the people around you. There is a clear link between secondhand smoke and heart disease. Smoking around your children can have especially severe health consequences. Children of smokers tend to have more lung illnesses, including pneumonia and bronchitis; may develop asthma; and are more likely to develop chest illnesses.

Could it be too late to stop smoking?

It’s never too late to stop smoking! Your health risks start decreasing quickly after you stop smoking, and they continue dropping over time. You’ll see big benefits after you quit, no matter how long you’ve been smoking – even if you’ve already developed some smoking-related problems.

Need more reasons to be a quitter?

Look at the health improvements you can expect within the first year:

And the benefits don’t stop there! Within several years your stroke and heart disease risk can equal that of a non-smoker’s and your risk of cancer will be dramatically reduced as well.

You’ll also see immediate benefits in your everyday life:

There’s one more important benefit to stopping smoking: You’ll save money! Smoking is expensive. When you stop buying cigarettes, the payoff is big.

What else can you do to protect your heart?

Stress

Researchers believe that there may be a relationship between the risk of a heart disease and environmental factors, such as stress. We don’t know if stress is an independent risk factor or if it contributes to other problems, such as overeating, smoking, physical inactivity, or high blood pressure and cholesterol levels. However, we do know that people who have a lot of daily mental stress have twice as high a risk of a heart attack.

Even if you’re under a lot of day-to-day pressure, there are ways to reduce your stress and put less strain on your heart. After you get the facts on stress, you can learn how to use them to get heart healthy.

What is stress?

Stress is the mental tension and physical condition caused by the way we react to physical, chemical, emotional or environmental factors. Everyone feels stress, but in different ways and in different amounts.

Women report experiencing higher levels of stress than men and are less likely to think they manage stress well enough. Stress can lead women to overeat, become inactive, drink alcohol, or smoke. All these behaviors are directly related to risk factors for heart disease.

What are the benefits of managing stress?

You will find that as you manage your stress, you will

Family History

It’s no secret that heart disease can run in families. In fact, your family’s health history may be one of the strongest influences on your risk of developing heart disease.

You have a higher risk of heart disease if you have a family history of “early heart disease.” That is, a father or brother who had heart disease before age 55 or a mother or sister who had heart disease before age 65.

While you can’t change your genes, you can change many behaviors that affect them. Therefore, you need to understand the risk factors that impacted your family. Did your father have high cholesterol? Did you mother have high blood pressure? Knowing this information can help you take action to protect your body against its genetic tendencies.

That’s why it’s important to record your family’s health history. To make sure you’re fully aware of any health risks that run in your family, it’s wise to gather a written family health history.

Start by interviewing your parents and siblings. The health histories of other close blood relatives can also hold important clues, so be sure to include your children, aunts, uncles, and grandparents, too. Just follow these simple steps:

What else can you do to keep history from repeating itself?

Having a family history of heart disease doesn’t mean you will get it. Your lifestyle and health habits give you a lot of control. These are smart steps to follow:

Age

Until age 55, a man and woman have the same risk of heart disease. But at 55, a woman’s body changes in ways that put her at increased risk.

What roles do hormones play?

As women reach menopause, their bodies begin to make less of the estrogen and progesterone hormones, ending menstruation and fertility.

What about Menopausal Hormone Therapy?

Once thought to be a preventive measure for heart disease, researchers have learned that long-term use of hormone replacement therapy (HRT) in menopausal women poses serious risks and may increase the risk of heart attack or stroke. Research now shows that:

If you are undergoing HRT, talk to your doctor about the pros and cons.

What else can you do to protect your heart?

Celebrate your age and remember that you’re never too old to get heart healthy. By embracing changes now, you can ensure a longer, better future. You can do it!
