  * Myocardial infarction within the past 6 months

    * Patients who have had a myocardial infarction 6-12 months ago are eligible provided they are asymptomatic and have a negative cardiac risk assessment (i.e., treadmill stress test, nuclear medicine stress test, or stress echocardiogram)
  * Angina upon ordinary physical activity

    * Angina only with strenuous, rapid, or prolonged exertion allowed
  * ECG with evidence of cardiac ischemia, as defined by the following:

    * ST depression of ≥ 2 mm, measured from isoelectric line to ST segment
    * T-wave inversion ≥ 4 mm, measured from isoelectric line to peak of T-wave
  * NYHA class II-IV congestive heart failure
  * Known left ventricular ejection fraction \< 40% by MUGA scan or \< 50% by echocardiogram or MRI

* No uncontrolled hypertension, defined as persistent blood pressure ≥ 160/95 mm Hg despite medical management
* No clinically significant active infection, including known HIV infection or hepatitis B or C
* No other malignancy within the past 3 years except completely resected basal cell carcinoma or squamous cell carcinoma of the skin, in situ malignancy, or curatively treated low-risk prostate cancer
* No concurrent medical condition that, in the investigator's opinion, would compromise study treatment or assessment of toxicity

PRIOR CONCURRENT THERAPY:

* See Disease Characteristics
* At least 3 weeks since prior chemotherapy, radiation therapy or investigational agents. If steroids for cancer control have been used, patients must be off theses agents for at least 1 week before starting treatment. (Maintenance therapy for non-malignant disease with prednisone or steroid equivalent dose less than 10 mg/day is permitted)
* Prior allogeneic stem cell transplantation allowed provided all of the following conditions are met:
* Greater than or equal to 6 months have elapsed since allogeneic transplant
* No Graft vs. Host Disease (GVHD) is present
* More than 4 weeks since prior bortezomib
* No concurrent oral hormonal contraceptives
* No concurrent potent or moderate CYP3A4 inhibitors
* No concurrent anti-arrhythmic agents
* No concurrent treatment with any drugs that are generally accepted to having a risk of causing torsades de pointes (class 1 drugs)

  * Class 2 or 3 drugs allowed at the discretion of the investigator
* No other concurrent systemic therapy for the malignancy
* Concurrent warfarin (coumadin) allowed
