This thread is pretty sad...
It's been known for some time that clenbuterol at high doses causes cardiac necrosis. This study in animals shows that doses of 1 mcg/kg BW induce apoptosis (programmed cell death) in heart tissue. Humans not uncommonly ingest this much clen. For instance, in a 220 lb (100 kg) bodybuilder this translates to 100 mcg.

{beta}2-Adrenergic receptor stimulation in vivo induces apoptosis in the rat heart and soleus muscle.

High doses of the beta2-adrenergic receptor (AR) agonist, clenbuterol, can induce necrotic myocyte death in the heart and slow-twitch skeletal muscle of the rat. However, it is not known if this agent can also induce myocyte apoptosis and whether this would occur at a lower dose than previously reported for myocyte necrosis. Male Wistar rats were given single subcutaneous injections of clenbuterol. Immunohistochemistry was used to detect myocyte specific apoptosis (detected on cryosections using a caspase 3 antibody and confirmed using annexin V, single-strand DNA labelling and TUNEL). Myocyte apoptosis was first detected at 2 h, and peaked 4 h after clenbuterol administration. The lowest dose of clenbuterol to induce cardiomyocyte apoptosis was 1 microg kg(-1), with peak apoptosis (0.35 +/- 0.005 %; P<0.05) occurring in response to 5 mg kg(-1) . In the soleus, peak apoptosis (5.8 +/- 2 %; P<0.05) was induced by the lower dose of 10 microg kg(-1). Cardiomyocyte apoptosis occurred throughout the ventricles, atria and papillary muscles. However, this damage was most abundant in the left ventricular subendocardium at a point 1.6 mm, that is, approximately one-quarter of the way from the apex towards the base. beta-AR antagonism (involving propranolol, bisoprolol or ICI 118,551) or reserpine was used to show that clenbuterol-induced myocardial apoptosis was mediated through neuromodulation of the sympathetic system and the cardiomyocyte beta1-AR, whereas in the soleus direct stimulation of the myocyte beta2-AR was involved. These data show that when administered in vivo, beta2-AR stimulation by clenbuterol is detrimental to cardiac and skeletal muscles even at low doses, by inducing apoptosis through beta1- and beta2-AR, respectively.
T3 for your girlfriend is ok. Replace the Clen with albuterol if you MUST use some kind of stimulant. Anyone dumb enough to still use clen, AT LEAST bump your taurine intake up. If you can read, I dont see how you can continue to keep your gf on clen in good conscience. There are some other effective OTC supplements that can be added to help and they are actually good for you (sesamin, green tea (50% EGCG), TTA...)
I would even favor generic meridia over Clen. The only downside of meridia is increased blood pressure. In fat people w/ poor heart health it can be dangerous. Ironically, this is exactly who gets an RX. This is why there have been some deaths due to tubbies with already poor heart health keeling over with increased BP and palpitations. For people in good shape its pretty safe (much safer than Clen or DNP). All it does is effect serotonin levels and kill your appetite. It is not a stimulant and doesnt effect the thyroid or anything. You can get a month worth for ~$45-50 (generic) pretty easily.
This knowledge is not new. There is no excuse to remain ignorant...
