Save a Man’s Heart!

Obesity-waist circumference by Victovoi via Wikimedia Commons Copyright Public DomainHaving seen enough episodes of Grey’s Anatomy (or ER or any of a dozen other TV shows about medical practitioners) you may well know the amount of work a doctor can put in to save a man’s heart. OK, that is television and not real life.  As doctors, we love to save lives! We prefer to do it preventatively and proactively.

 

So… what does it take to save a man’s heart? It is easy; exercise, limited alcohol consumption, no cigarettes and a healthy BMI are the keys. The more items a man follows from this list, the better protection for the heart.

 

Here’s what blew our collective mind:

 

80% = the number of heart attacks in men that are preventable with a healthy lifestyle. Eighty!

36% = the risk reduction of heart attack by not smoking

12% = the risk reduction of heart attack by keep a waist measurement below 37”

3% = the risk reduction of heart attack by exercising on a regular basis

 

These numbers come from a recent study in The Journal of the American College of Cardiology. And also from the land of amazingly great news.

 

Get yourself or your man on the road to your best possible health by engaging in a healthier lifestyle and make those numbers work in your favor!

Shoulders, Knees and Toes, Knees and Toes

Over the next few posts we’re going to highlight some common injuries affecting familiar joints. As the title suggests, we’re starting near the top.

 

But before we get ahead of ourselves and start talking about these individual parts, let’s talk about how we image them…

 

There are many techniques for imaging the body, and the ones we use depend upon the type of injury and the most likely tissues injured. Here’s a gimme: broken bones? We’ll start with an x-ray – perhaps a CT if it’s complex. Here’s a not-so-gimme: soft tissue injury like torn ligament? Options here include MRI, ultrasound and arthrograms.

 

First off, not every injury is imaged. Why? Sometimes a careful exam by your doctor can answer the question – imaging in these cases is not done, unless symptoms do not improve in the expected manner. There are carefully developed rules helping your doctors determine who will benefit the most from imaging in the case of many of the common injuries, for instance ankle sprains.

 

After your doctor’s initial evaluation, you may be sent for imaging. In many cases this will start with conventional films (x-rays) to exclude fractures or other bony changes. Beyond that, a patient will be directed based on the clinical concern.

 

Imaging of patients who have multiple sites of injury from a fall or motor vehicle accident for instance may be done with CT. This allows quick evaluation of bones as well as some types of soft tissue injuries. Multiple structures can be evaluated at the same time with CT, such as looking for fractures in the lower back, while also assessing the abdomen for signs of damage to internal organs.

 

Soft tissue damage, such as torn cartilage or ligaments, will often not be apparent on a conventional film. Visualizing soft tissues can be done with ultrasound, MRI or an arthrogram (where contrast material or dye is introduced into the joint space). We may follow the arthrogram with imaging with MRI or CT.

 

So… we will start our journey of the joints with your shoulders! (See you Thursday!)

Heart Health: CT Coronary Angio

Here is an image from a CT coronary angiogram showing the aorta (the main blood vessel coming out of the heart and bringing blood to the body) with the coronary arteries coming off the aorta and going around/to the heart – the heart has been removed from the image so we can see the vessel, much like is seen on a heart catheterization. These arteries show no significant narrowings.

Here is an image from a CT coronary angiogram showing the aorta (the main blood vessel coming out of the heart and bringing blood to the body) with the coronary arteries coming off the aorta and going around/to the heart – the heart has been removed from the image so we can see the vessel, much like is seen on a heart catheterization. These arteries show no significant narrowings.

Now that we’ve covered CT coronary calcium scores, we’d like to talk more about noninvasive heart imaging.

There are several ways of studying artery narrowing or blockages of the coronary arteries of the heart. Two common exams are the CT angiogram of coronary arteries and the coronary angiogram, also known as a heart catheterization or “heart cath.”

For a CT angiogram, radiologists use CT technology and intravenous contrast to noninvasively image the arteries. A heart catheterization, usually performed by a cardiologist, uses a small catheter threaded through the blood vessels to the heart to inject contrast into the arteries.  The exam may require light sedation, and the use of catheters in the heart has risks including but not limited to blood vessel damage, arrhythmias, bleeding and stroke.

It has been shown that 40% of heart catheterization procedures in women and a smaller percentage in men are normal.  In those cases, nothing is wrong with the arteries and nothing requires treatment like angioplasty or stenting.  Having a less invasive, safer exam to evaluate people at risk for heart disease or symptoms of heart disease is a bonus – particularly for those patients with lower risk and potentially normal coronary arteries.

CT angiography of the coronary arteries uses CT, EKG, intravenous contrast and sophisticated 3D post processing techniques to create 3D images of the heart and heart arteries for analysis. Both soft plaques and calcified arterial plaques can be imaged and analyzed for severity. The determination for noninvasive or invasive treatments can be made from this study. The  procedure takes approximately 30 – 60 minutes, requires little preparation and the results are shared with the ordering physician for further review.

For patients at high risk for coronary artery disease, or those likely needing intervention such as angioplasty (treating narrowed arteries with a balloon) or stenting, a traditional heart catheterization is recommended. This allows diagnosis to be followed by immediate treatment.

CT coronary angiography can be considered for the following patients among others:

  • Patients with a strong family history of heart disease.
  • Patients with multiple risk factors for heart disease such as hypercholesterolemia, hypertension, diabetes.
  • Patients with atypical chest pain.

Talk to your medical provider if you have questions regarding this examination or questions regarding your personal risk for heart disease.
