After extreme poverty and associated infectious diseases,
eradication of heart attack can be the most rewarding
opportunity in the 21st century for saving productive life years
worldwide.

Global Atherosclerosis; A Bigger Threat than

•Heart attack is not equal to heart disease, and is not equal to atherosclerosis either.
It is the attack part of coronary heart disease that is most devastating, and the first focal point of the AEHA movement.
Heart attack is the tip of atherosclerosis problem.

From Vulnerable Plaque to Vulnerable Patient
What have we learned in the past 5 years.• More than one vulnerable plaque exists and rupture prone plaques are
not the only type of vulnerable plaques. Besides plaque, blood and myocardial vulnerability must be considered.
• Coronary calcification is a marker subclinical disease and can identify the vulnerable patient. The level of calcification directly correlates with the level of risk.
• The need for measuring disease activity through inflammatory markers or else remains high and currently unanswered. CRP does not seem to be the one.
• Noninvasive CT imaging has taken the lead in the race among diagnostic technologies. Molecular imaging holds the future.
• The hot race among emerging intra-coronary vulnerable plaque detection technologies slowed. IVUS made a come back.
• Aggressive lipid lowering reduces adverse events, nonetheless CHD patients experience over ~10% MACE every year.
• Drug eluting stent has become the final contender in the fight against restenosis. Its role in pre-emptive therapy of non-culprit non-flow-limiting plaques remains to be defined.
![Page 20: From Vulnerable Plaque to Vulnerable Patient ; Our Mission Is Eradication of Heart Attack](https://reader036.fdocuments.net/reader036/viewer/2022062520/56815747550346895dc4e968/html5/thumbnails/20.jpg)
From V Plaque to V PatientWhat to expect in the next 5 years.
• Noninvasive screening of the vulnerable patient with CT and IMT will be improved and widely practiced.
• Molecular imaging for the detection of vulnerable plaques with different target molecules will rise, nonetheless, its use for clinical practice remains far from 5years.
• Combined LDL-HDL therapy will be the mode of treatment. Emerging anti-inflammatory drugs may find a role but limited.
• The new coming of IVUS will expand its use in cath labs, however, the magnitude of success in systemic drug therapy will define the future of vulnerable plaque detection.
• Rapid acting systemic drugs for plaque stabilization may obviate the need for the detection of vulnerable plaques, unless they are extremely expensive.
• The outcome of pre-emptive DES clinical trials versus the outcome of emerging drug trials will define the direction of preventive cardiology to 2010 and after. The direction may go to more non-invasive or may open the floodgate to preventive interventional cardiology.

In this meeting you will learn how screening for the detection and treatment of the vulnerable patient presents as a “low-hanging” fruit of preventive cardiology.
