How Is It Diagnosed And Treated
To determine whats causing your symptoms, a doctor will take a careful medical history and give you a physical examination. If the doctor suspects an acute coronary syndrome, the following tests will be performed:
- A blood test can show evidence that heart cells are dying.
- An electrocardiogram can diagnose an acute coronary syndrome by measuring the hearts electrical activity.
If tests confirm blood flow to the heart has been blocked, doctors will work quickly to reopen the artery. Minute by minute, the heart is accumulating irreversible damage. So time is myocardium myocardium being the heart muscle itself, Bolger said.
At San Francisco General Hospital, the goal is to have the artery reopened within an hour of the patient entering the hospital, Bolger said. Generally, patients do best when the artery is reopened within four hours of the first symptoms.
Treatment for acute coronary syndrome includes medicines and a procedure known as angioplasty, during which doctors inflate a small balloon to open the artery. View an illustration of coronary arteries.
A stent, a wire mesh tube, may be permanently placed in the artery to keep it open. For hospitals not equipped to do angioplasty quickly, drugs may be used to dissolve blood clots, but more hospitals are making the procedure available in a timely manner, Bolger said.
Cardio Exercise Heart Rate
Your cardio exercise heart rate has a big impact on the outcome of your workout. Keep it too low and you won’t induce the stress that helps your cardiovascular and respiratory system improve let it run too high and you’ll burn out before your workout is through.

The factors that determine your heart rate during cardiovascular exercise include age, sex, fitness level and exercise goals. It’s possible to increase your cardiovascular fitness by exercising at 50 to 70 percent of your maximum heart rate but a rate of 70 to 90 percent is considered ideal. Your maximum heart rate is influenced by your age, gender and genetics.
Vigorous: 77% To 95% Of Mhr
The vigorous heart rate zone is from 77% to 95% of your maximum heart rate. You are now in the vigorous-intensity zone. You will be breathing very hard and able only to speak in short phrases.
This is the zone to aim for when training for endurance. It spurs your body to improve your circulatory system by building new blood vessels and increases your heart and lung capacity. Aiming for 20 to 60 minutes in this zone is believed to give the best fitness training benefits.
With the increase in intensity, you burn more calories in the same amount of time, as you are covering more distance in that same time. The calories you burn depend most on distance and your weight. If you go farther in the same amount of time, you burn more calories per minute.
In the vigorous zone, you burn 50% of your calories from carbohydrates, less than 1% from protein, and 50% from fat.
You would typically be in this zone by running or cycling, but you could achieve it by racewalking or walking fast for an aerobic walking workout.
When you train at the high end of this range , this intense exercise will improve the amount of oxygen you can consumeyour VO2 max. This exertion level takes you to the limit where your body begins to produce lactic acid. Runners, cyclists, and racewalkers use this zone to build their ability to go even faster.
In the high end of the vigorous zone, the body burns 85% carbohydrates, less than 1% protein, and 15% fat.

Whats The Difference Between A Fat
Your different heart rate zones are determined by the percentage of your maximum heart rate. If you’re exercising too close to your maximum heart rate, this could place an unhealthy strain on you.
Knowing the difference between fat-burning heart rate and cardio heart rate can help you understand how much you should push yourself in different exercises. Reaching your target heart rate zones more efficiently then helps improve your cardiovascular health.
The different exercise heart rate zones are based on training levels connected to your maximum heart rate. Your heart rate can be broken down into three zones:
Lower-intensity zone. This zone is when you’re working at 50% to 60% of your maximum heart rate. In this zone, you’re burning fewer calories, but you can sustain this rate for longer.
Fat-burning zone. Also called the temperate zone, you’re using 60% to 70% of your maximum heart rate when exercising at this intensity. Typically, about 65% of the calories you burn in this zone are from fat.
Aerobic zone. This is the highest level of intensity. You’re using about 70% to 80% of your maximum heart rate. At this heart rate, only 45% of your burning calories are fat. However, you’re burning more calories than you are in the other two zones. While you’re not burning the maximum amount of fat calories, you’re improving your overall health. You’re likely not able to sustain the aerobic heart rate for long periods of time.
Are Jumping Jacks Cardio
Instead, cardio exercises help burn fat all over your body, including your belly. Certain exercises also help build and tone muscles. Vigorous types of cardio activity, such as jumping jacks, help you burn overall fat quicker because of their high intensity and the large number of calories that are burned.

Target Heart Rate For Exercise
Your target heart rate is 50 to 85 percent of your maximum heart rate. It is the level at which your heart is beating with moderate to high intensity. To determine your maximum heart rate, take 220 and subtract your age.
Sustaining a workout at this pace improves cardiorespiratory endurance. So knowing your target heart rate helps you pace your workouts. Exercising at the right level of intensity will help you avoid burning out or wasting time with a workout thats not vigorous enough to help you meet your goals.
What Should Your Heart Rate During Exercise Be
Heart rate increases during physical activity, meaning the heart performs more beats per minute to meet the demand of delivering oxygenated blood around the body and to the working muscles. According to the American Heart Association , there are many long-term health benefits associated with regular exercise that elevates the heart rate, including improved circulation, lower blood pressure, lower levels of ‘bad’ cholesterol, and a reduced risk of heart disease and stroke.
The heart is a muscle, and conditioning it to work more effectively with exercise also lowers your resting heart rate , which is a marker for good health. A normal RHR for adult men and women ranges between 60-100 beats per minute and a 2013 study published in Heart Journal found that an elevated RHR is not only an indicator of poor physical fitness, but a risk factor for mortality.
Using heart rate as a training metric is an effective method to improve health and fitness and it’s not a new concept. According to the American Council on Exercise , it’s an accurate way to gauge how hard the body is working during exercise in order to get the associated cardiovascular benefits, without putting a strain on your system.
You can achieve different levels of intensity by incorporating an exercise machine into your workings, and you can monitor your heart rate with most of the best fitness trackers.

What Are Exercise Heart Rate Zones
Heart rate zones are a percentage of your maximum heart rate . Exercise too close to your maximum HR and your heart and body will struggle to keep up with the demands.
The goal of heart rate zones is to make you the most efficient, but to allow you to challenge yourself to improve cardiovascular fitness, says Travers.
Exercise heart rate zones are the training levels based on your maximum heart rate. As you increase your pace, cadence and workload, you increase the demands on your heart. Travers breaks it down:
- Lower-intensity zone: Youre exercising at 50% to 60% of your max heart rate. At this point, 85% of the calories you burn are fat. The downside? Youre burning fewer calories overall than you would if you were exercising at a higher intensity. Youre generally able to sustain this zone the longest amount of time.
- Temperate zone: Youre exercising at 60% to 70% of your max heart rate. Roughly 65% of the calories you burn are fat.
- Aerobic zone: Working at 70% to 80% of your max heart rate puts you in the aerobic zone. About 45% of the calories you burn are fat. But youre burning a higher number of overall calories compared to the other heart rate zones. You generally sustain this zone the shortest amount of time.
How Long Do You Have To Do Cardio
The Basic Guidelines for Cardio Frequency. The frequency of your workouts will depend on your fitness level and your schedule. The general guidelines are: For health, try moderately intense cardio 30 minutes a day, five days a week, or vigorously intense cardio 20 minutes a day, 3 days a week You can also do a

Whether youre a professional athlete who trains for several hours or you have a low to moderate routine, keep your body hydrated with small, frequent sips of water.
Platt notes that you dont need to eat during a workout thats an hour or less. But, for longer, high-intensity vigorous workouts, she recommends eating 50-100 calories every half hour of carbohydrates such as low-fat yogurt, raisins, or banana.
How To Get Your Heart Rate Up
Its essential that some of your exercise make your heart beat fasterthan it does when youre resting.
Exercise is an important part of disease prevention and that includes cancer prevention, too. But not all exercise is created equal. Its essential that some of your exercise make your heart beat faster than it does when youre resting.
Getting your heart to beat faster trains your body to move oxygen and blood to your muscles more efficiently, helps you burn more calories and lowers your cholesterol. All of this can help you stay healthy and lower your cancer risk.
According to the American Institute for Cancer Research, 150 minutes of moderate physical activity or 75 minutes of vigorous exercise each week can help lower your cancer risk. Its the vigorous exercises that can help you get your heart rate up.
How to measure your heart rate
So, how do you determine your heart rate? One of the easiest ways to measure your heart rate is with a monitor, says Whittney Thoman, exercise physiologist at MD Andersons Cancer Prevention Center. This is typically a watch or a strap that goes around your arm or chest that syncs with a watch or another device. Many wearable fitness trackers now include heart rate monitors.
Understanding your heart rate
Now that you know how to measure your heart rate, you can determine:
Check your pulse or your heart rate monitor while youre resting and then again while youre exercising to compare your resting heart rate to your active heart rate.

Ways To Assess Fat Burning
When measuring exercise intensity, youâll consider how you feel and your actual heart rate.
How do you feel? The first way to measure the intensity of your workout is by taking note of your perceived exertion. This differs from person to person. What may seem like a difficult run to one person could feel like a simple jog to another. This is a subjective measure of how your workout is going.
Heart rate. Measuring the intensity of your workout with your heart rate is a more objective way to look at it. The higher your heart rate while working out, the higher your exercise intensity is. This also means youâre more like to achieve fat burning in your exercises.
An activity tracker can track your heart rate for fat burning and cardio. These wrist monitors will help you keep track of your perceived exertion and how that correlates with your heart rate. This will help you get a better idea of when youâre actually in a fat-burning state.
Q: What Is A Recovery Heart Rate
A: This is the heart rate your body will drop to after two minutes, after stopping an exercise session. For instance you exercised for 30 minutes and your heart rate was at 155. Two minutes after you stopped exercising, your heart rate then decreased to 95. This recovery heart rate measure helps to evaluate your overall heart fitness level. Use this measurement to compare between exercise sessions.

Significance Of Heart Rate
To determine where your intensity lies, you must first figure out your maximal heart rate. The maximal heart rate is age dependent, for as we grow older, the heart beats a little more slowly. To find maximal heart rate, subtract your age from 220. The fat burning and cardio zones are defined as a percentage of this maximal heart rate.
Cardio And Heart Rate
A heart-rate zone that improves cardiovascular fitness is defined as between 55 and 80 percent of maximum heart rate, according to the American Council on Exercise. A less-conditioned individual may see benefits to her heart health at the lower levels of this recommended zone while an athlete needs to work at a higher intensity to improve fitness.
The fat-burning zone occurs at the lower end of the cardio zone â between 55 and 70 percent of maximum heart rate. When working at this intensity, a greater percentage of calories burned comes from stored fat.

After: Refuel Your Tank
After your workout, Ms. Platt recommends refueling with:
- Fluids. Drink water, of course. Blend your water with 100% juice such as orange juice which provides fluids, carbohydrates.
- Carbohydrates. You burn a lot of carbohydrates the main fuel for your muscles when you exercise. In the 20-60 minutes after your workout, your muscles can store carbohydrates and protein as energy and help in recovery.
- Protein. Eat things with protein to help repair and grow your muscles.
Its important to realize that these are general guidelines. We have different digestive systems and a lot depends on what kind of workout youre doing, Platt said.So do what works best for you. Know that what you put in your body is as important as you what you do with your body . Both are crucial to keeping your engine performing at its best.
A Tale Of Two Workouts
Researchers compared two workout strategies in healthy adults ages 70 to 77 during a five-year study in Norway .
The moderate-intensity continuous training workout involved exercising for 50 minutes. Participants aimed for a target heart rate of 70% of their estimated maximum heart rate.
The “4×4” HIIT workout, which lasted 43 minutes, followed this pattern:
1. 10-minute warm-up at 60% of maximum heart rate
2. Four minutes of high-intensity exercise at 85% to 95% of maximum heart rate
3. Three minutes of lower-intensity exercise at 60% of maximum heart rate
4. Repeat steps 2 and 3 three times, for a total of 4 cycles
5. Five-minute cool-down.
Note: To get a rough idea of your maximum heart rate, subtract your age from 220. For 60%, multiply by 0.6 for 85%, multiply by 0.85, and so forth. As an example, the estimated maximum heart rate for a 75-year-old would be 220 75 = 145 60% of that would be 145 × 0.6 = 87.

What Are Cardio Heart Rate Zones
Find out how heart rate training can maximize your workouts, by understanding cardio heart rate zones.
Cardio heart rate zones are a feature of many exercise programs, but what are they and how can they help you get fitter? Whether you’re going for a steady run or increasing your stroke rate on a rowing machine , exercise that gets your heart pumping improves cardiorespiratory fitness, builds stamina and burns calories.
Some of the best fitness trackers will track your heart rate for you but there’s some debate how how accurate these tools are.
In this article, we look at the role of heart rate during exercise and explain how training within cardio heart rate zones can improve fitness levels along with ways to include them in your cardio workouts. Find out about heart rate variability , or read on for key information on cardio heart rate zones, and the science behind it, so you can get in the zone.
How To Check Your Pulse And Heart Rate
Exercise is an important part of cancer prevention. You need 150minutes of moderate physical activity or 75 minutes of vigorousexercise each week to help lower your cancer risk. Your heart rate canhelp you determine if the exercise youre doing is moderate orvigorous.
If youre working at 50 to 70% of your maximum heart rate, then thatexercise is considered moderate. If youre working at 70 to 85% ofyour heart rate then its vigorous exercise.

What Works Best
study , however, researchers discovered that wrist monitors may be just as accurate.
As a result, the monitor you choose may come down to personal preferences, your exercise of choice, budget, and any features the specific device has.
The best workouts to get you into your fat-burning zone vary from person to person. The key is to monitor your heart rate during different activities to see where you land and go from there.
For fat-burning, stick with moderate activity. Try the talk test if youre unsure how hard youre working. If you cant talk during your exercise, youre likely working at vigorous levels. If youre slightly out of breath, but can maintain a conversation, youre likely working at moderate levels and may be in your fat-burning zone.
Another way to determine your exercise intensity is by your individual capacity. Moderate, fat-burning activities may feel like an of your capacity on a scale from 1 to 20. If you start feeling like youre more at 17 to 19, slow down this is more vigorous activity.
Here are some exercises that may help you reach your fat-burning zone:
- ballroom dancing
While you may be focused on fat, its still important to elevate your heart rate into the vigorous zone from time to time. Working harder strengthens your cardiovascular system and burns more calories than moderate activity.
Besides exercise, there are other healthy habits you can start that may help you lose fat and reduce your overall weight.
