Antinuclear antibody detected on Cardiolipin AB (IGG) results, implication?

I am 39 and have just been diagnosed with 'connective tissue disease' by two doctors based on physical examinations alone. My physical symptoms include red swelling fingers and edema in feet. I have Raynaud's. I have developed a few small red marks on my face which the doctor says are broken blood vessels. I easily lose my breath and have heart palpitations at rest. I suffer from increased body stiffness, and asymetric joint deterioration in MCP joints in hands. Last blood tests normal except for very low Immunoglobulin IGG levels. This battery of blood tests is normal except for ANA detection on Cardiolipin AB test. Anyone out there familiar with these symptoms or lab results?
