The science of feeling emotions

By: | September 30, 2016 image03

When you receive good news, your heart soars! Conversely, when you hear terrible news, you might feel a sinking feeling or deal with what is known as heartache. Ever wondered how emotions can affect you physically? How exactly do intense emotions have a direct effect on specific feelings in our body?

This study in 2010 published in the Scientific American explains that this experience is linked to the anterior cingulate cortex, a region of the brain that is believed to regulate emotional reactions. Robert Emery and Jim Coan, professors of psychology at the University of Virginia, theorize that the anterior cingulate cortex becomes more active during high intensity and stressful situations.

Keep your arteries clean

Coronary artery disease, the most common type of cardiovascular disease, is the narrowing or blockage of the artery or arteries supplying blood to the heart muscle. This narrowing is caused by plaques, which are cholesterol deposits on the vessel wall, resulting in abnormal and gradual thickening of the lining of the heart arteries, a condition known as atherosclerosis.The narrowing usually develops slowly over many years.

If this sounds like a harrowing experience, that’s because it probably is. Patients who smoke, or have conditions such as diabetes mellitus, hypertension and high blood cholesterol or fat levels are much more prone to developing coronary artery disease.

Debunking the defibrillator myth

By: | September 23, 2016 image08

Watch enough detective or hospital television dramas and you’re bound to notice dramatic scenes where doctors attempt to bring patients back to life using a defibrillator! In reality, defibrillators are typically used on patients with cardiac dysrhythmias, also known as irregular heartbeat, and ventricular fibrillation.

As the name suggests, defibrillation stops fibrillation, the useless trembling that a person’s heart muscles can adopt during a cardiac arrest. Simply put, a defibrillator works by using a high-voltage to pass an electric current through the heart so it’s shocked into working normally again.

Tennis elbow: not just for tennis players!

By: | September 17, 2016 image05

Tennis elbow, known medically as lateral epicondylitis of the elbow, occurs due to a small tear in the tendon(s) on the outside of the elbow that attach the forearm muscles to the elbow joint. The micro tear and subsequent development of the damaged tissue is due to forceful and repetitive forearm use. Tennis elbow by definition is most commonly associated with tennis, hence its name, but it can occur in any sport or work that requires forceful and/or repetitive forearm usage.

Most tennis elbow diagnoses are not related to actually playing tennis! For example, painters, plumbers, landscapers, butchers, office or house cleaners, assembly-line workers, golfers and baseball players all can develop the condition. Read More

Are you having a heart attack?

By: | September 13, 2016 image02

If you’re able to read this coherently, you’re probably not! It’s a common misconception that heart attacks occur out of the blue, as there are several symptoms and warning signs that can help you detect an early onset of a heart attack. According to the Centers for Disease Control and Prevention, more than 70 percent of the 735,000 heart attacks reported each year are first-time heart attacks. This means that only a minority of reported heart attacks had no prior symptoms!

While there are a list of symptoms to look out for which can be indicators of a heart attack, these same symptoms are sometimes caused by problems other than an impending heart attack. But there is no way of knowing for sure without proper medical advice so remember, it’s always important to promptly contact a medical provider if you experience these symptoms. Read More

Tearing your ACL

By: | September 7, 2016 Torn Anterior Cruciate Ligament

If you watch football enough or keep a social circle with avid fans, you probably know what an ACL (also known as anterior cruciate ligament) tear is and what it means for football players. The anterior cruciate ligament (ACL) is in the middle of the knee and it prevents the shin bone from sliding out in front of the thigh bone. In turn, an anterior cruciate ligament injury is the excessive stretching or tearing of the anterior cruciate ligament in the knee. A tear may be partial or complete and for obvious reasons, the injury can be career ending for a football player. Read More
