Journalist and "Today" show co-anchor David Bloom was covering the war in Iraq when he collapsed and died from a blood clot in 2003 at just age 39, according to USA Today. Bloom had been traveling extensively in close quarters for long periods of time. He had complained of pain and cramping in his leg behind the knee just three days before his death. But he kept going, skipping out on recommended medical treatment, and the deep vein thrombosis progressed to a fatal pulmonary embolism. Today, his wife, Melanie Bloom, works to promote DVT awareness with the Coalition to Prevent DVT.
Actress Zsa Zsa Gabor
Glamorous red carpet-siren Zsa Zsa Gabor from Hollywood's golden era was rushed to the hospital in 2010, at age 93, because of severe swelling in her leg. She was diagnosed with a massive blood clot, reported CNN. Confined to a wheelchair after a car accident in 2002 and a survivor of several strokes, Gabor had many of the risk factors for deep vein thrombosis.
