Item 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION

On February 28, 2005, CAS Medical Systems, Inc. (the "Company") issued the press
release attached hereto as Exhibit 99.1 announcing the results of operations and
financial condition for the fourth quarter and fiscal year ended December 31,
2004.


Item 4.02. NON-RELIANCE ON PREVIOUSLY ISSUED FINANCIAL STATEMENTS OR A RELATED
AUDIT REPORT OR COMPLETED INTERIM REVIEW

On February 24, 2005 the Company's Board and Audit Committee, after consultation
with the Company's management, concluded that the Company's financial statements
for periods ended from March 31, 2002 through September 30, 2004 should no
longer be relied upon because of an error in such financial statements. The
error relates to the failure to apply the accounting standards of FAS No. 106,
EMPLOYERS' ACCOUNTING FOR POST-RETIREMENT BENEFITS OTHER THAN PENSIONS to a
post-retirement benefit plan (the Plan). Under FAS No. 106, companies are
required to estimate the total future cost of providing postretirement benefits
and recognize that cost over the employees service period. Prior to the
Company's adoption of FAS No. 106, the Company was utilizing a cash basis method
of accounting for the expenses associated with the Plan.

The Plan was established in January 2002 for qualifying employees who reach age
sixty-five and have provided ten years of service to the Company. The Plan
provides certain prescription drug and supplemental health benefits for Medicare
qualified retirees of the Company.

The Company will correct and include restated financial statements in its Annual
Report on Form 10-KSB for 2004 and in its quarterly reports on Form 10-QSB for
2005. In connection therewith, the Company will decrease net income previously
reported for 2003 of $737,000 or $0.08 per share basic and $0.07 diluted to
$561,000 or $0.06 per share basic and $0.05 diluted and will increase the net
loss previously reported for 2002 of ($325,000) or ($0.03) per share to
($497,000) or ($0.05) per share.

The Company has discussed this matter with its current registered public
accountants, UHY LLP. That firm was appointed October 7, 2004. The Company has
initiated but has not concluded discussions with its predecessor auditors
PricewaterhouseCoopers LLP about this matter. That firm was dismissed October 7,
2004.
