Dialogue with a Doctor: 4 Things You Should Know About Heart Health

Why is heart health so important? Granted, everyone knows it’s important to eat “heart healthy” and exercise for the health of your heart, but what is it about this particular organ that requires such time and attention? What should you know to keep your heart operating at optimum levels? Dr. Barbara Joy Jones, one of the lead physicians for Gwinnett Medical Center’s Corporate Health program, breaks it all down – one step at a time.

Your heart is the biggest organ of the cardiovascular system. When the heart is cared for, the rest of our veins, arteries and capillaries are cared for.

The heart’s main job is to pump oxygen- and nutrient-rich blood throughout the body (and it does this about 115,000 times a day and 42 million times in year). “Your heart pumps blood to the entire body, and a strong, resilient heart supports the body during rest and physical activities. While the heart is the biggest organ in the cardiovascular system, veins, arteries and capillaries are also critical components,” said Dr. Jones. “They are one big working system,” she added, “and thus their health is vital.”

Biometric screenings can provide insight into the health of your heart.

A biometric screening can help identify any significant cardiovascular or nervous system problems through several measurements including: cholesterol levels and glucose; blood pressure; and a measurement of height, weight and body mass index (BMI). “Having a biometric screening gives you a baseline,” said Dr. Jones. Elevated numbers can indicate a number of issues that include:
  • High cholesterol
  • A risk for prediabetes
  • Elevated blood pressure can reflect lack of sleep, high unmitigated stress or a high sodium diet
But, here’s the good news: improved nutrition and diet, exercise and sleep can be all helpful in addressing these issues. “Furthermore,” adds Dr. Jones, “if you do have an elevated reading like blood pressure at a screening, you can be directed to your primary care physician for further workup.”

Prevention is key.

“The body does a great job of compensating," says Dr. Jones. “So, by the time you actually have symptoms of disease, there is damage already done.” She emphasizes paying particular attention to symptoms like headaches, shortness of breath, dizziness, leg swelling and chest pain, and seeing your Primary Care physician as soon as possible.

There is a surprising link between emotions—both positive and negative—and heart heath.

Several studies strongly suggest that certain psychosocial factors such as grief, depression, and job loss contribute to heart attack and cardiac arrest. Stress may affect risk factors for heart disease such as high blood pressure. It may also spur on risky coping behaviors that impact heart health, such as smoking, overeating, drinking too much alcohol and physical inactivity.

But, overall, emotional stress causes a negative chain reaction within your body by releasing stress hormones—cortisol and adrenaline. They prepare your body to deal with stress by increasing heart rate and blood pressure, as well as narrowing blood vessels to help push blood to the center of the body.

After your stress subsides, your blood pressure and heart rate should return to normal. If you're continually stressed, your body doesn't have a chance to recover which may lead to damage of your artery walls.

It isn’t just stress and frustration that impact heart health; the opposite is true, too. In a recent research review, studies showed that people with a positive outlook tended to have lower blood pressure levels and healthier cholesterol and blood sugar levels.

Although it’s not entirely clear how optimism and heart health are connected, researchers believe optimistic people may have greater buffers against stress, a factor in heart disease risk. Dr. Jones reminds us to try mindfulness training, such as yoga, tai chi, or meditation. Another healthy technique is the adoption of habits to increase optimism by making a list of what you’re grateful for, or identifying and building on your personal strengths.

A Risk Assessment Checklist – 3 Things to Remember

According to the National Safety Council, a worker is injured on the job every seven seconds. That equals 510 accidents per hour and 12,600 a day! However, what’s most startling is that each accident could be prevented. In an effort to combat these statistics, Gwinnett Medical Center (GMC) implemented a culture of safety to not only protect their employees, but the patients whom they care for. GMC’s Occupational Health experts rely heavily on a risk assessment that encompasses three major elements when caring for their employees.  While there are a number of safe guards already in place, these three key approaches are utilized most frequently, according to  Roger Burnett , GMC occupational health manager:   Risk Identification: Find, recognize and record hazards Risk Analysis: Understanding consequences, probabilities and existing controls Risk Evaluation: Comparing levels of risk and considering additional controls Risk Identification Through extensive resear

The 3 B's to a More Relaxing Work Day

Life comes at you hard and fast, and there are some days when the pace only seems to increase. In addition to the typical stressors of life, modern technology ensures fewer opportunities to escape. There is always a blue light, a buzz or a beep that’s not too far away. So, what’s the most effective and efficiency way to recover? It turns out that it’s easier than you think, and involves the three B’s: body, breathing and breaks.

Stop The Cycle: A Diabetes Expert Gives 4 Tips For Diabetes Prevention

Today’s technology provides us with a number of warning signs. Examples include signs of car trouble like a fuel warning light or low tire pressure, and text message alerts about severe weather. These indicators call for action and in many cases help to avoid larger issues. Our bodies function very similarly. Our bodies let us know that something more serious might be on the horizon and deserves prompt medical attention. The more familiar and attuned we are with our bodies, the more quickly warning signs become apparent and thus the call for action. It’s no different with pre-diabetes. According to the CDC, approximately 84 million American adults—more than 1 out of 3—have prediabetes. Of those with prediabetes, 90 percent don’t know they have it. The following are signs and symptoms of prediabetes: Being overweight Being 45 years or older Having a parent, brother or sister with type 2 diabetes Being physically active less than three times a week A history of gestational diabet
