In Breitbart's case it would be heart enlargement, which causes the heart to pump less efficiently. It also causes rhythm problems. As the heart becomes less efficient, it works harder which causes more enlargement, and the cycle continues. Many times there are no symptoms because of this compensation. And the first symptom is sudden death.
Any unknown, little known drugs that can induce that (like muscle relaxers, etc)?
Long term cocaine use can cause a lot of heart problems, but I guess you're asking if this could be murder. I doubt it. High blood pressure is the most common cause, and I believe Breitbart's family said they knew he had heart problems.
Actually, his father-in-law told reporters initially that he didn’t know of any heart problems that Andrew had. In the same article, the spokesman for the coroner’s office said he hadn’t seen a doctor for over a year. Then when people started wondering if he had been a victim of a heart attack dart - which leaves no signs in toxicology reports and the only sign it DOES leave is the small prick-hole where the dart went in (looks like a bug bite) - his friends started claiming that he had been suffering heart problems. First off it was a claim that he had moved his office closer to home because he was having heart problems, then it was that he had been taking medication, then it was that he had been hospitalized for 2 weeks after a heart attack.
But this toxicology report makes all of those sound suspicious - especially when taken with the 2 conflicting claims from the coroner’s office - that he hadn’t seen a doctor in over a year and that he had no prescription medicines in his system.
A person who’d had a heart attack within the last year and wanted to be around to take care of his little kids - AND to come out with damaging information on Obama before the next election - would take heart meds to keep from having another heart attack.
Add to that what we know now: that the technician in the coroner’s office who apparently did photography for special cases died of arsenic poisoning the day before this report came out.
Nothing in this report contradicts a heart attack dart. It does contradict chronic heart problems or a heart attack within the last year. And the person who may have photographed the body - one of the only people who would definitely know whether the photos of the dart entry hole were subsequently manipulated or deleted - was killed by arsenic poisoning the day before this report came out.
Also keep in mind that Breitbart fell to the ground dead less than 5 hours after telling Joe Arpaio that Joe’s evidence regarding Obama’s fraud and forgeries was good and that he was glad Joe would be reporting it to the public the next day. The day Breitbart died was the day that Joe’s posse reported probable cause for fraud and forgery on Obama’s BC and draft registration, and the same day that Rush Limbaugh received a bomb scare. For some strange reason, the press refused to report the evidence that was shown at that presser... They were too busy reporting on Breitbart’s death. (And they haven’t reported on the evidence TO THIS DAY).
