Being the strongest muscle in the body, the hearts purpose is to pump blood through our blood vessels through rhythmic contractions. To regulate blood pressure and volume, the heart secrets “ANF”, which is a very powerful peptide hormone. It affects the regulatory region of the brain, as well as the kidneys, blood vessels, and the adrenal glands. First off, i would like to clear up a worldwide rumor; the Heart is not located on the left side of your body! Its actual location is found in the center of your chest, just SLIGHTLY of to the left hand side, and underneath the sternum. For protection, the heart is enveloped in a sac called the pericardium, and is surrounded by the lungs. First thought is, “why does the strongest muscle in the body need so much protection?”. It’s fragile! Weighing in at about 300 grams, the heart consists of 4 chambers; 2 lower ventricles and 2 upper atria. Valves between the atrium and the ventricle control proper blood flow from one to the other.
The job of pumping blood everywhere in the body is a huge responsibilty. Each and every beat of the heart consists of a sequence of events called the cardiac cycle. “Cardiac” is greek, meaning “heart”. There is 3 major steps in the sequence: atrial systole, ventricular systole and complete cardiac diastole. After the blood has completely left the atria, the atrioventricular valves (located between atria and ventricular chambers), close to prevent backflow. This function is what you would recognize as your heartbeat. Next, there is a contraction of the ventricles and flow of blood into the circulatory system. This is known as the ventricular systole. Once again, valves called “pulmonary” and “aortic semilunar” close to prevent backflow. After these 2 steps, the heart takes a quick break called complete cardiac diastole. This allows the refilling of blood and to start the process over.

Heart disease is the #1 killer of women in America. Approximately 1 in 3 women die each year due to heart attack or stroke. Nearly twice as many women die of heart disease or stroke, than they do of any form of cancer, including breast cancer. Women are less likely than men to seek medical attention when having a heart attack. For this reason it is important to know the warning signs and symptoms and what to do in the event you feel you are having a heart attack.
Signs and symptoms of a heart attack:
Shortness of breath, often without any chest pain
Flu-like symptoms such as nausea, clamminess or cold sweats
Unexplained fatigue, weakness or dizziness
Pain in the chest, upper back, shoulders, neck, or jaw
Feelings of anxiety, loss of appetite, discomfort.
If you notice one or more of these warning signs, don’t wait more than a few minutes. Do not wait longer than 5 minutes. Call 911 right away!! If you are driving in your car at the time, it is imperative that you pull the car over as soon as possible. You could lose consciousness at any moment. If you have any available and you have no known allergies to aspirin, chew 1 regular tablet of aspirin while you wait for medical help to arrive.
Here are some tips on how you can avoid having a heart attack.
Quit smoking
Eat a healthy diet and cut back on foods high in saturated fats and sodium.
Control your blood sugar if you have diabetes.
Exercise regularly. This may sound difficult if you’re not one who exercises but start out slowly. A brisk walk 30 minutes a day can reduce your risk of a heart attack.
Lose weight if you are overweight.
Control your blood pressure if you have hypertension.
A healthy lifestyle that includes exercise and eating right could help decrease your risk of heart disease and heart attack and increase your longevity.
