5. Defendants have denied liability as to the heart attack during post-surgery and related subsequent surgery.
6. Plaintiff's average weekly wage in this claim is $1,008.31.
• Exhibit 1: Executed Pre-Trial Agreement
• Exhibit 2: Plaintiff's medical records
2. On September 9, 2008, Plaintiff sustained an injury to his low back while unloading washers in the course of his employment.
3. Defendants admitted liability for Plaintiff's September 9, 2008 injury on a Form 60 dated October 2, 2008.
4. Following the September 9, 2008 injury, Plaintiff came under the care of Dr. Voos, who on February 9, 2010 performed a lumbar interbody fusion at L4-5 and L5-S1 for treatment of the admittedly compensable back injury. Before the surgery, Plaintiff underwent testing to confirm that he was fit for surgery, including an EKG on January 6, 2010, the results of which were interpreted as normal.
5. Plaintiff did not have any physical symptoms of a heart attack, such as shortness of breath or chest pains, either before or after his back surgery.
6. On February 13, 2010, while Plaintiff was still hospitalized from the back surgery, he underwent a cardiac workup because of an episode of hypotension. An EKG done on February 13, 2010 showed evidence that Plaintiff was having an ischemic event. An EKG done on February 14, 2010 showed that Plaintiff had suffered a heart attack sometime within the previous few days.
7. Following his discharge from the hospital, Plaintiff came under the care of Dr. Verde, an internist and cardiologist in training who first saw Plaintiff on March 10, 2010. Further cardiac work-up revealed that Plaintiff had 70 to 80 percent blockages in three main arteries of his heart. Because the blockages put Plaintiff at a high risk of suffering a massive *Page 4 heart attack and sudden death, it was recommended that Plaintiff undergo a coronary artery bypass. Dr. Koutlas performed the bypass surgery on April 23, 2010.
8. Blockages in the arteries related to coronary artery disease develop gradually over many years. There is a genetic predisposition to develop coronary artery disease. Risk factors such as smoking, high blood pressure, and low levels of "good" cholesterol increase the likelihood that someone will develop coronary artery disease.
9. Plaintiff has a family history of coronary artery disease. In 1997 he suffered a heart attack. Plaintiff has an 18-year history of smoking more than a pack of cigarettes a day. He also has a history of high blood pressure and low "good" cholesterol.
10. Dr. Verde opined, based upon her review of the cardiac monitoring records from Plaintiff's February 2010 hospitalization, that the myocardial infarction that was diagnosed on February 14, 2010 happened sometime between noon on February 9, 2010 (after the back surgery was completed) and February 12, 2010.
11. Dr. Verde indicated, and the Full Commission so finds, that Plaintiff's need for the bypass surgery was unrelated to the myocardial infarction that he suffered sometime between noon on February 9, 2010 and February 12, 2010. Dr. Verde further opined, and the Commission so finds, that based upon the cardiac catheterization results, Plaintiff would have needed the bypass surgery regardless of whether he had had the myocardial infarction after the back surgery. There is no expert testimony of record to establish a causal link between Plaintiff's February 9, 2010 back surgery and his coronary artery disease or need for the bypass surgery.
12. There is likewise no expert medical evidence to support a finding that Plaintiff's back surgery caused the myocardial infarction he suffered sometime between noon on February 9, 2010 and February 12, 2010. Dr. Verde's testimony that surgery under anesthesia can cause *Page 5 stress on bodily organs is not sufficient to support a finding that Plaintiff's February 2010 heart attack was caused by his surgery, nor does it support a finding that the surgery aggravated Plaintiff's preexisting coronary artery disease to the point that he suffered the heart attack.
2. In cases involving complicated questions of medical causation, plaintiff must present competent expert medical evidence that the injury for which defendants admitted liability caused the condition complained of. Click v. Pilot Freight Carriers, Inc.,
2. Each side shall bear its own costs.
This the ___ day of November, 2011.
